Because Minmetals and Jiangxi Tungsten guided down this month, tungsten concentrate market pessimism spread powder market price confusion, some hold stocks for the return of funds to start cheap Paohuo, however, the downstream demand continues to slump, the overall volume is still biased low. Expected short-term tungsten products market continues steady weakening trend.

Tungsten powder and tungsten carbide temporarily stable prices low, currently concentrated in price between 234-236 yuan / kg, renewable WC non-tax price 209-212 yuan / kg, tungsten offer 380-410 yuan / kg, steel tungsten 255-260 yuan / kg, black tungsten rod 340-360 yuan / kg, transient stability sidelines.

Overseas tungsten City stabilized temporarily stable. The 7th night MB ferrotungsten Rotterdam offer 36.9-37.5 US dollars / kg tungsten, paratungstate Europe offer 325-345 US dollars / metric ton, the Hong Kong offer $ 339-360 / ton degrees, are stable. Expected short-term overseas tungsten City or maintain steady trend.

Tungsten market: guided collective decline, bearish market sentiment strong, 60 scheelite 88,000 yuan / ton immune to take the goods, market purchases of low willingness to late tungsten prices still slipped risk. Waste tungsten market confidence slump, businesses will significantly enhance Paohuo, low-cost emerging, some have been losing money shipping, the downstream demand still sluggish, low overall volume. Sodium tungstate tablet market unsalable serious, factory orders scarce, sodium tungstate smelter is a small multi-family starts, strict control of raw material procurement and product inventory.

Tungsten scrap prices continue to fall, low-cost emerging

After this month, guided tungsten ore bodies down, tungsten City pessimism spread, waste tungsten market confidence slump, businesses will significantly enhance Paohuo, low-cost emerging, some shipments have been at a loss, the downstream demand still in the doldrums, the overall volume of partial low. Short-term market is expected to more than scrap tungsten will continue to run downwards.

Tungsten scrap prices continue to fall. Currently scrap tungsten drill price excluding tax concentrated in 162-165 yuan / kg, down 4 yuan. Imported scrap tungsten blades and drawing dies 157-161 yuan / kg, down 2-3 yuan, 155 yuan a small amount of the transaction. Domestic scrap tungsten blade 150-153 yuan / kg, transient stability. 70 degrees above the grinding tungsten scrap material 1.5-1.55 yuan / kWh, 50-70 degrees 1.45-1.5 yuan / kWh, 30-40 degrees 1.3-1.35 yuan / kWh, transient stability.

Tungsten difficult to take the goods, price continues to fall

Details: Category: Tungsten's News; Published on Friday, 07 November 2014 13:56; Written by HJF; Hits: 922

This month Ganzhou tungsten APT Association released the latest forecast average price of 152,000 yuan / ton, compared with October down 8000 yuan / ton, with larger decreases, it is still far higher than the actual market price. It is understood, APT manufacturers offer concentrated in the 14.9-15 yuan / ton, then the actual trading 145,000 yuan / ton immune to take the goods. APT smelter home runs difficulties increase, the lack of effective support for the market late, late mainstream market quotations or fell to 145,000 yuan / ton in the vicinity, and more ground gas.

Sodium tungstate tablet market unsalable serious, factory orders scarce, sodium tungstate smelter is a small multi-family starts, strict control of raw material procurement and product inventory. Individual businesses eager to sell stock to ease the financial pressure, and lower pricing, resulting in 96% sodium tungstate market price is slightly confusing, within 11.4-12 yuan / ton price range have appeared.

Further Studies on Tungsten Carbide Cutting Tool Fatigue Are Needed

Details: Category: Tungsten's News; Published on Thursday, 06 November 2014 18:27; Written by xjq; Hits: 948

Tungsten carbide cutting tool, with high intensity, abrasion resistance and hardness, is widely used in the cutting machining. However, the tungsten carbide cutting tool fatigue problem is one of the primary reasons that are restraining its growth.

Tungsten carbide cutting tool is normally used in bad working condition and has to suffer from cyclic loading, thermal cycling and corrosion. Tungsten carbide cutting tool fatigue is one main factor contributing to tool damage. The types of tool fatigue include mechanical fatigue, thermal fatigue, corrosion fatigue, etc. In mechanical fatigue, tools suffer from alternating tension and compression as well as impact under cyclic loading and finally produce fatigue crack even if the mechanical stress has not yet reached the limit of tungsten carbide’s intensity. In thermal fatigue, the tungsten carbide cutting tool, interacting with its environment, surfers from thermal cycling, which results in its Internal energy changing and finally the tool material will produce crack source which can expand to microcracks. In corrosion fatigue, the components interact with the corrosion medium in the environment when used and caused crack or break. However, in is in fact that these types of fatigues are interacting at the same time during the actual applications of tungsten carbide cutting tools.

Currently, the reports about tungsten carbide cutting tools intensity account for a great majority, while researches about its toughness and fatigue property are few. In order to improve the core competitiveness in the international market especially the high-end product area, China should carry out further researches on the tungsten carbide cutting tool fatigue problem.
