Tungsten, cobalt, molybdenum as the representative of the small metal ushered in "spring"
In the copper, nickel prices soaring agitation futures market, "a pool of spring water", the cobalt, tungsten, molybdenum as the representative of the small metal also ushered in the spring.
February 23 opening, due to the market reported that the three major cobalt suppliers Huayou Cobalt, Greenpeace, Jinchuan International suspended offer reluctant to sell, cobalt concept stocks rose. As of the close, A shares of the market Grammy, Huayou Cobalt, Luoyang Molybdenum, Shengtun Mining are reported daily limit.
Securities Times e company reporter learned that since February, cobalt spot quotes have skyrocketed nearly three percent, tungsten prices also increased by more than 20% year on year. And in the fundamentals, driven by the recent listing of listed companies is also steadily higher. The industry believes that small metal price fluctuations are mainly affected by market supply and demand situation, the market outlook is expected to remain the main shock upstream.
Cobalt rose nearly 30% in January
"22 days of the market price of cobalt from 39 million / ton to 420,000 yuan / ton, but the current price is uncertain, some manufacturers have stopped the offer, the market is chaotic." Long-term concern Cobashi business analyst Ye Jianjun told Reporter, February 22, cobalt reference price of 377,000 yuan / ton, and February 1 294,000 yuan / ton price, or up to 28.16%.
It is reported that the current rise in cobalt prices began in October 2016. When the spot cobalt offer about 210,000 yuan / ton, 4 months the cumulative price increase of nearly 80%.
Today's hot metal cobalt, in October last year before the price has been low. Observed nearly a year of cobalt price chart is not difficult to find, in February last year to October, the price of cobalt has been entrenched in the 210,000 yuan / ton price range, until the current round of market was sharply pulled up.
Driven by the current round of rising prices of cobalt on the one hand is the external disk prices continue to pull, on the other hand is the pressure on domestic environmental protection caused by limited. He said that the pre-domestic cobalt prices by overseas guidance of strong, but the current domestic cobalt prices have covered foreign media Cobalt prices. Yesterday part of the manufacturers and dealers to suspend foreign offer, bullish expectations are strong, is expected to focus on the recent quake market stability. Late should pay special attention to the downstream demand side of the growth and price tolerance.
"The highest price of cobalt sold to 800,000 yuan / ton, but after the beginning of 2008 all the way down, many companies have burst losses or collapse." A brokerage analyst said the current round of cobalt prices soared, but also on After the long-term downturn in the retaliatory rebound. It is expected that the relevant enterprises within the industry will benefit.
Accompanied by rising cobalt prices, the domestic listed companies have recently been favorable.
Huayou Cobalt shares since the opening on February 16 41.25 yuan / share, rose to 23 days on the 23.57 yuan / share, or up to 37%. Over the same period, Green shares from 6.5 yuan / share rose to 7.87 yuan / share, or 21%. While the Luoyang Molybdenum also rose from 4.35 yuan / share to 5.5 yuan / share, or more than 26%.
China Merchants Securities, the latest research report that the price of cobalt downstream ternary material rose more than the rise in cobalt prices, which will inevitably produce the downstream chain of goods and the stock market reluctant to worry about the stock. Cobalt is a positive cycle mode to start, will accelerate up. Cobalt 2017 is expected to shortage of about 3,000 tons, with oil prices and new energy vehicles to accelerate sales, the gap may continue to grow. At the same time, cobalt prices rose coincides with the start of the colored cycle, the cobalt industry valuation will continue to improve. Recommended Luoyang Molybdenum, Huayou Cobalt, Green.
Tungsten prices are also optimistic about the market outlook
The current round of non-ferrous metals rally, or more obvious there are small metal tungsten.
"Tungsten City out of the door in 2017. Since the beginning of February, metal tungsten quotation has risen about 6,000 yuan / ton, and now the mainstream offer in the 78,000 yuan / ton, up 20.9% year on year.
causing the current round of tungsten prices up the main reason is the environmental pressure. At present, domestic tungsten resources are mainly concentrated in Hunan and Jiangxi provinces. As the mining will cause dust pollution, so the local raw material mining enterprises are mostly in the maintenance shutdown. At the same time, after the tungsten ore operating rate is still low, coupled with environmental protection pressure, the current mining enterprises reluctant to sell the mentality of the obvious, the downstream business procurement more and more difficult.
tungsten is a national strategic reserve resources, in order to protect the rare metals from speculation in the market crash, affecting the normal market sales. Domestic large-scale tungsten products listed companies will sign a long bargaining agreement to ensure price stability. Tungsten market has a guide price, the market also has a stable effect.
Raw material tungsten prices, the downstream carbide prices also formed an impact. It is reported that tungsten is the main raw material for the production of cemented carbide, the current production of tungsten carbide from the beginning of February 17.1 million / ton has risen to 180,000 / ton.
In the A-share market, tungsten-related listed companies also performed well. Xiamen tungsten industry on January 17 opening offer 19.7 yuan / share, 23 close at 25.09, or 27%. At the same time, Zhang source tungsten rose 20%.
the future tungsten market prices or showing a steady rise in the market, with the downstream industry chain manufacturers continue to increase production costs, sales prices followed by shocks is expected in the first quarter tungsten product market prices will show a comprehensive recovery trend.
The ceramic tool has been implemented to replace some of the carbide cutting tools
With the combination of tool technology and machine tool technology, workpiece materials and tool materials to promote each other, aerospace manufacturing industry continues to develop. It can be said that the continuous development of tool materials is the driving force for the continuous development of aerospace manufacturing. At present, aerospace manufacturing industry widely used tooling grades up to thousands of models, according to the tool material to divide, nothing more than the following categories: tool steel (carbon tool steel, alloy tool steel, high speed steel), carbide , Ceramic and superhard tool material. Carbon tool steel is suitable for manufacturing hand tools, carbon tool steel T10A and T12A applications are more extensive.
In the aviation manufacturing industry, the proportion of carbide cutting tools is the largest. Carbide tool in the aviation manufacturing is the leading tool, the scope of application is quite wide, in the NC tool material dominated. Carbide has become the main tool material, so that the cutting process to achieve the transition to the carbide age, due to different grades of carbide characteristics of different characteristics, and therefore its scope of application is also different. Carbide can be used not only to manufacture a variety of machine can be translatable tool, and can create a whole type of end mills, reamers, taps and drill bits. Carbide tools are divided into ordinary hard alloy, coated carbide, ultrafine particles of cemented carbide, carbon (nitrogen) titanium-based cemented carbide.
YT-type cemented carbide with YG class and YW class most of the excellent performance in the aerospace manufacturing industry is more widely used. Coated carbide has a higher hardness than the matrix, wear resistance, heat resistance, widely used. Ultrafine particles Carbide can be used in a wide range of intermittent cutting. Carbon (nitrogen) titanium-based cemented carbide is mainly used for the continuous surface finishing and semi-finishing of steel parts.
At present, China's ceramic tool application is still in its infancy, the actual application of the development of slower. Ceramic cutting tools are mainly used for hard alloy cutting tools(or carbide tools) difficult to cut the workpiece roughing. Aerospace manufacturing industry to promote the use of ceramic tools for a long time, in the ceramic tool geometric parameters, cutting the amount of use and technology need to accumulate experience. Ceramic materials Compared with cemented carbide, ceramic materials have higher hardness, thermal and abrasion resistance. Ceramic tool chemical stability, antioxidant capacity are better than carbide, very suitable for dry continuous high-speed cutting high-temperature alloys, hardened just, bearing steel, high strength steel and other difficult to process materials. Aero engines in the application of many high-temperature alloys, shaft parts more, it is the ceramic tool to play its advantages. To achieve efficient processing, to replace some of the ceramic cutting tool carbide tool is completely feasible. Ceramic tool is not a universal tool, only the correct use in order to give full play to its superiority.
China's carbide industry patent work from scratch to develop very quickly
Carbide industry chain from a relatively long, from the initial tungsten ore to the final carbide and its products in all aspects of the industry chain can achieve greater value-added space. Preliminary estimate, from the initial raw material concentrate powder made of metal powder, the product value of about 3 times; from the concentrate to the ordinary carbide, can enhance the product value of about 6 times; from the concentrate to the CNC lathe rotary blade, Product value of more than 20 times.
China's carbide industry from the 1950s started, through the introduction of technology, digestion and absorption, independent innovation in the past 60 years of development. Domestic carbide companies gradually grow and develop, whether from the number, size, or from the technology have made great progress. As the market through the early extensive development, carbide companies began to gradually attach importance to research and innovation capabilities, intellectual property protection awareness continues to strengthen, the cemented industry patent work from scratch, the development of change quickly. At present, the domestic engaged in carbide research universities and research institutes more than 30, the proportion of technical staff accounted for about 10%.
From the cemented carbide industry patent application data, before and after 2006, cemented industry, new patent growth began to grow rapidly, and reached its peak in 2014. In 2006, the number of new domestic patents for cemented carbide was only 169, and the number of new patents reached 661 by 2014.
China's carbide production accounts for about 40% of the world, but sales of nearly 20%
China's carbide production accounts for about 40% of the world, but sales of nearly 20%, high-performance high-end products less development of such products is the top priority of carbide development. More likely:
1, cermet tool carbide
Metal ceramic tool components generally contain 20% of the WC, tool materials are Al2O3, Si3N4, Sialon and so on. Cermets can be made into indexable inserts or the overall tool (reamers and cutters) are mainly used for applications where the finishing surface is required. Ceramic cutting tools in the processing of hardened steel, Incol718 and other difficult to process materials, the coated carbide Tool with a higher processing efficiency.
2, sub-fine carbide
Submicron carbide accounts for nearly 25% of the world's cemented carbide market and continues to increase. As the computer, mobile phones and other products to the miniaturization of development, at the same time due to update the better PVD coating technology support. PVD coated blades are usually in fine cutting and are therefore consistent with the trend of industrial near net forming.
3, gradient cemented carbide
Gradient Carbide (which does not contain off-beta-based cemented carbide) is a hot topic in recent years and can be divided into C gradient, Co gradient and grain size gradient, or both. Can be applied to cutting tools, mining tools and wear parts. In addition, the gradient cemented carbide may also be used as the matrix of the super-hard material composite sheet to improve the bonding strength between the cemented carbide and the diamond / boron nitride interface.
4, cutting tool carbide
In addition, the cutting tool is the largest value of carbide products in a piece, the domestic coating can be transferred to 70% of the blade market to rely on imports, this part of the carbide material should focus on the development.
But also includes ultra-coarse crystalline cemented carbide, can be used as a mining alloy for fracture toughness is the main reason for the failure of the occasion; mesh (biphase) carbide alloy alloy ball teeth; unbonded phase carbide for optical Lens molds, water jet nozzles, etc .; rare earth cemented carbide, such as in the Co bonding phase to add Re and Cr elements, improve the carbide die die processing performance.
