Following report dated on Feb. 21, 2013, to the application of tungsten heavy alloy rods for balance shafts of aero engine, China North Industries Group announced recently, with the roar of 36,000 tons of ferrous metals vertical extrusion machine of Inner Mongolia North Heavy Industries Group Company, a high-temperature powder alloy rod came out, which marked a tremendous breakthrough in the extrusion technology applied to powder turbine disk material for aero engine.
Known as the crown of the engine, turbine disk is the most critical core component in aero engine. The high-temperature powder alloy materials are the essential material for manufacturing high-performance, high reliability and long-life advanced aero engine turbine disk. So far, the extrusion technology of aero engine powder turbine disk material had been only mastered by Wyman Gordon Company in U.S. and Abu Dua in France and served for their own aviation industries.
The turbine disk powder material system of aero engine and the powder disk processing technology for engine in China is close to that in Europe and in U.S.. However, due to the equipment limitation, the extruding and cogging technology of large amount of deformation, one of the key technologies in manufacturing the powder disk hasn’t been implemented. North Heavy Industries Group’s construction of 36,000 tons of ferrous metal vertical extrusion machine offered the basic measure to solve this problem effectively, and realized a leapfrog development in this technology. Wang Wuxiang, the expert and researcher of Chinese well-known aerospace materials said, excitedly in the scene of extrusion trial:“North Heavy Industries Group has just realized another decades-long dream of Chinese aviation during the past several years.”
The success of the trial allows North Heavy Industries Group to give full play to the production capacity of 36,000 tons of ferrous metals vertical extrusion machine and consolidated the technical foundation of improving the competition ability of specialty materials and products.

Tungsten mine prices are in transient stability, the actual delivery price of 65 degrees wolframite is 115,000 yuan.Sodium tungstate market shows chilly and price changes fatigue. In ferro-tungsten market some manufacturers began to cut down offes, the range of market price widened and the proposed price of scrap tungsten market remained in the vicinity of 175,000yuan. They keeps the attitude of wait-and-see on the whole.
Downstream demand is sluggish, businesses lack of confidence and expected that tungsten market turnover is difficult to have a big breakthrough for short term.
Macro perspective, the exchange rate of the RMB against the U.S. dollar is 6.21yuan, creats the first breakthrough among 19 years; price adjustment of refined oil starts and may be return to the time of 7 yuan. Euro zone and the IMF is determined to provide 10 billion euros to aid Cyprus.

The tungsten mine market runs steady, the mainstream prices of 65 degrees wolframite are concertrated in 11.5-11.7 yuan / ton, the mainstream prices of scheelite are concertrated in 11.3-11.6 yuan / ton.According to the response from others, recent tungsten mine prices tend to weak, the actual transactions are general and the contract prices are concentrated in 115,000 yuan / ton.
Although, some merchants’ prices are too high, the space for bargaining is relatively large. The weak market leads to many businesses loss confidence in the market. And the volume of the backlog of funds tight, the shipment transaction price had to move closer to the lower one. Right now, the basic tungsten mine market consolidation is completed and tends to equilibrium price. Manufacturers around temporarily to promote the deal, the will of price adjustment ist not strong. Expected that tungsten mine market will run stabily in short term.

With ferro-tungsten prices weak downstream, the trading atmosphere is reduce step by step. In addition, businesses operating enthusiasm is affected by the variable climate and raining day, prices continued running weak. It is expected that ferr-tungsten market is hard to change the weak pattern for short-term.
Scrap tungsten market keeps stable temporarily. The mainstream transaction prices of domestic ferr-tungsten blade that are not taxed are concentrated in 170-173 yuan / kg, imported blades 179-182 yuan / kg, scrap tungsten drill 189-191 yuan / kg, scrap pure tungsten blocks 210-213 yuan / kg. Mainstream transaction price scrap tungsten grinding material W content of more than 70 degrees of 1.72 yuan / kWh; 50-70 degrees, 1.62 yuan / kWh; 30-50 degrees 1.46 yuan / kWh.
