Carbide since the beginning of the 1920s , with its "widia" ( like diamond ) the name of the market by the German scientists since the invention and production of tungsten tensile modulus get first industrial applications , replacing the expensive diamond then stretched mode .

Our Carbide started late , but rapid development . Currently, carbide die basically serialization and standardization. In recent years the development of the situation, the theoretical study of carbide tooling and design has a deeper and more science, applied more widely .

In the development of new alloy materials on behalf of a few years ago to drill for the hot iron and nickel . Metallurgical materials such as Hunan province developed the equivalent of YG, YG20, YG25 the strength and toughness of cemented carbide, received good results in for cold heading die , cold extrusion die and so on. Tianjin Institute on behalf of the iron-nickel carbide drill also developed a considerable YG (15-20) of carbide tooling materials, standard parts in the roll forging , cold heading steel ball YG20 quite effective with respect .

In recent years, new research is popular fine grain , ultra-fine grain , and even gradient nanocrystalline carbide and carbide . There are gradient cemented carbide composition gradient , gradient structure , in addition to the molten metal is also useful to produce osmotic gradient cemented carbide processing methods , such as the top of the gradient cemented carbide hammer .

Fine grain and ultrafine grain carbide also available, such as fine-grained YGS drawing dies while drawing <φlmm wire , is three times the normal drawing mode .

In addition, cast- inlaid carbide hot die , and achieved good results in terms of rolling and wire rod rolling .

Today, tungsten City mainstream stabilized, but the lack of demand for support , some products fell slightly empty spot transactions scarce , businesses are waiting for tungsten ore , tungsten Association guidance issued, the operation is not positive sentiment is very strong . Tungsten concentrate prices being weak stability maintenance, thinly traded , buyers continued to lower prices , but the market is still hovering between 1.4-1.45 mainstream yuan / kWh .

Despite the recent war in Ukraine , the domestic tungsten market to stimulate domestic demand and so good , but these effects are indirect, slow , changeable , tungsten market is still a lack of effective demand for direct support is expected in May if there is no external force , such as purchasing and storage , tungsten City or difficult to have a big breakthrough , May or low consolidation mainly forthcoming guidance or continue to decline, but the magnitude is small.

Tungsten market : demand continues to slump tungsten , tungsten market was weak , mainstream tungsten scrap prices continue steady run , the market is not trading volume and turnover are mostly small batches , lack of business confidence in the market outlook more confused . Not more than the overall quantity of cash resources . Scheelite agency guidance to be announced this month , the market waiting to see thicker atmosphere , tungsten scrap market is expected to more than short-term maintenance of stability will be temporary . Tungsten concentrate prices being weak stability maintenance, thinly traded , buyers continued to lower prices , but the market is still hovering between 1.4-1.45 mainstream yuan / kWh .

During the May Day holiday, the mainstream tungsten scrap prices continue steady run , the market is not trading volume and turnover are mostly small batches , the overall amount of the cash resources were not many . Scheelite agency guidance to be announced this month , the market waiting to see thicker atmosphere , tungsten scrap market is expected to more than short-term maintenance of stability will be temporary .

Tungsten scrap prices steady. Currently scrap tungsten drill focused on the purchase price excluding tax mainstream 185-188 yuan / kg, imported scrap tungsten blade 176-180 yuan / kg, domestic waste tungsten blade 167-170 yuan / kg, scrap wire drawing dies 178-181 yuan / kg waste pure tungsten 213-221 yuan / kg. W ≥ 70% concentrated in the purchase price of the grinding material mainstream 1.75-1.8 yuan / kWh ; 50%
Overseas tungsten City remained stable. 2 evening MB Rotterdam ferrotungsten offer $ 43-43.5 / kg tungsten , ammonium paratungstate Europe quoted 358-365 U.S. dollars / metric ton , quoted in Hong Kong dollars 362-370 / metric ton , steady . Expected short-term overseas tungsten Costco will continue steady run .
