Different Opinions of Tungsten Manufacturers, Tungsten Quoted Price Tends to Stable at Short Term

Tungsten market : at the present, many tungsten manufacturers have different opinions, although some big tungsten companies stick to hold the high quoted price of tungsten series products. However, some small tungsten factories indicated that tungsten afternoon market will not too bright to continue. Besides, they thought that after tungsten afternoon market upward trend there may turn down and to fall. So at the present market about tungsten series products quotation is in chaos condition and there is little transaction as well. The solicited quote of tungsten series products is tend to stable at the short term.
The average price of mainly tungsten series products: wolframite concentrate (content ≥65%): 66,000.00 RMB/ton; scheelite concentrate (content ≥65%): 64,000.00 RMB/ton; ammonium paretungstate (content ≥88.5%): 100,000.00 RMB/ton, export price:220.00 $/ton; tungsten powder (content ≥99.95%): 162.00 RMB/kg, export price: 24.00 $/kg; tungsten carbide powder (content ≥99.7%): 160.00 RMB/kg, export price:23.00 $/kg; tungsten bar (content ≥99.95%): 215.00 RMB/kg, export price: 34.22 $/kg.
As follow are our company series molybdenum and tungsten products’ price: copper plating (W72): specification: 175×35×4, price:108 RMB for one; cemented carbide rod (YG10X): specification: φ3×330, price: 15.6 RMB for one; molybdenum sheet (content 99.95%): specification: 400×250×0.5, price: 218.5 RMB for piece; tungsten electrode (content 99.95%): specification: φ2.4×175, price: 6.957 RMB for one; tungsten alloy rod (content 90%): φ18×90, price: 150.00 RMB for one; tungsten billet (content 90%): φ7.15×54.6, price:31.00 RMB for one.

 

Tungsten alloy could be used for small diameter bomb

The attack of small diameter bomb (50KG) has been completely showed on Dec. 18 with its perfect and precise aggressive ability, especially, having tungsten alloy core for armor-piercing to get a better deadly high-explosive to the armored targets on the ground more accurate.

Also tungsten alloy prefabricated fragments are widely used for military defense as its high hardness, good impact force, excellent ultimate tensile strength, etc. The current high chamber pressure prefabricated artillery fragments, are used in canister form, such as Switzerland, L70-type 40 mm grenade where overhead is filled with tungsten alloy spheres. Tungsten prefabricated fragments technology has been widely used on all types of warheads nowadays.

Many Enterprises Continue to Restrict Sales, Tungsten Concentrate Market Price Goes up

tungstentungsten

Tungsten market : many big enterprises continue to restrict the sales of tungsten raw materials. Besides, many tungsten smelting factory even buy tungsten concentrate from foreign which make tungsten concentrate spot market has shortage of supply and the market price of tungsten concentrate is going up with small range. What’s more it will continue to going up with small increase.

China APT Export Analysis

According to research data, in 1981 China export ammounium paratungstate (APT) to oversea only 264 ton. From 1985 to now, the export volume of APT have soared. In 1985, APT export volume up to 4,114 ton and the volume increased every year. In 1993 the export volume increased to 9,886t and in 1988 the export volume arrived to 17,731 ton. The reason that export volume of APT have soared up was due to China government operated financial support policy for APT export. In the ‘90th the APT export volume accounted for more than 50% on total tungsten products export volume. Form 1995 to 1997, the tungstate which gave priority with APT (include tungstic acid, tungsten trioxide, sodium tungstate, other tungsten oxide and tungsten hydroxide) export volume accounted for 83%, 87%, 79% of total tungsten series products’ export volume. On the other hand, the volume of foreign exchange earned by export of tungstate account for 85.7%, 81.1%, and 77.4% of total tungsten series products export volume. 
On the international market, China’s APT mainly sales to Japan, USA, Korea, Netherlands and followed sales to Germany, Sweden, Belgium, Argentina, Canada, India and other countries.
In the’ 80th, Japan has 10 mines for production so the self-sufficient rate of tungsten arrived at 30%. However, these mines also shut up after 1993 and to import the raw material of tungsten is the only choice for Japan tungsten industry development. China has produced a large amount of APT and the export price of it also inexpensive so China’s APT has became the main source for Japan tungsten industry. In 1983, Japan imported 18 ton APT from China. In 1991, imported 299 ton and the import volume of APT accounted for 77.7% of total tungsten products import volume. In 1995, Japan imported 4,651 ton APT and other chemical products which was the highest level in history and 97% import volume was form China. In 1997, Japan imported China’s APT 4,132 ton accounted for 28.3% of Chian tungsten products total export volume. Japan every year will consume more than 6,000 ton’s tungsten and every year the import volume of APT, tungsten trioxide and other intermediate products account for 61% of total tungsten series products. Besides, more than 60% raw material imported from China. Japan imports APT instead of tungsten concentrate not only can reduce production cost and pollution for purity and highly processed products production, but also can improve product’s additional value.
