China has almost 70% of the global tungsten mineral resources, greater reserves, while more than 80% of annual output of tungsten is supplied by China. Overall, the five major groups in China have controlled more than 51% of tungsten resources in domestic and nearly 35% around the world. We expect the five major groups will have a wave of regulation on tungsten industry in our country in 2014 from monopoly of the global supply of tungsten. And tungsten is the irreplaceable foundation and strategic resource national for economy and modern defence. The future of tungsten demand will continue to maintain a rapid and stable growth rate.
Since the 1960 s, after scientists discovered electrochromic during oxidation of interim metal, more than 50 years of research have constantly lead to surprising results. Tungsten oxide not only has excellent electrochromic effect, also plays an important role in many other relevant field. The unique properties of tungsten oxide have the significant value and wide application foreground on photochemical water splitting into hydrogen, chemistry, biosensor, Photoelectron catalytic, high-temperature superconducting and other aspects. In recent years, the emergence of Nanostructured tungsten oxide will have a great influence on the science and technology.

Tungsten Oxide Price will Rise in The Second Half in 2014

In the first half of 2014, the price of tungsten oxide was to go down gradually. But most of the tungsten smelters are optimistic about the future market. Tungsten oxide is expected to rise in price. The sources in Xiamen tungsten industry said the second half of the export market will be more active and trading orders will increase significantly.
Supply of tungsten ore and APT has run short this year, while the price also has been slowly. At the same time, the price of tungsten oxide submitted by companies is too high. At present, most manufacturers enterprises have offered an average price in 153000 yuan/ton, and export markets of tungsten oxide has raised in recent months. The domestic where most tungsten smelters are optimistic about the future market and expect that the price will increases over the next few weeks.
Meanwhile, some analysts said, tungsten ore for declining production in overseas may promopt price substantially. Judging from the current situation, tungsten market will be well of the prospects.

Tungsten market: agency guidance unchanged, following last month, has guided two consecutive months to stabilize, which also laid the tungsten market is the recent trend broadly stable based. Tungsten ore miners continue to market the sidelines, thinly traded. APT and other smelter home quotes are flat, despite continued weakness in market demand, market volume was light, but manufacturers offer relatively strong, the actual turnover fell slightly compared to six weeks ago, the high acceptance of high-priced reduced. Sodium tungstate weak downstream demand, large smelter home delivery difficult, capacity utilization is very low. Tungsten has also come to difficult market volatility continues to remain stable business offer. Expected short-term price of tungsten products or continue to hold steady on the sidelines.

July agency quoted stabilize, and Minmetals no major action, APT and other smelters home quotes are flat, despite continued weakness in market demand, market volume was light, but manufacturers offer relatively strong, the actual turnover dropped slightly compared to six weeks ago, high acceptance high price decrease. It is understood, APT acceptance transaction price is typically 16.6-16.7 yuan / ton, cash transactions at 164,000 yuan / ton.
Sodium tungstate weak downstream demand, large smelter home delivery difficult, capacity utilization is very low. It is understood that 96% of current market quotations 12.7-13 sodium tungstate mainstream yuan / ton, or even 125,000 yuan / ton low.

The Principle of Armour-piercing Bullet

- Published on Wednesday, 09 July 2014 14:43
Armor-piercing bullet has a reputation for strong drill, as the saying goes, diamond cut diamond.
It mainly by the projectile hit targets in a large kinetic energy and high breakdown strength steel armor itself.To breakdown armor of the target without the great self-conditions is not enough. The projectile of armor piercing bullet is made by high-density tungsten alloy, which is harder than the armor of tank.
Every single bullet have hard warhead. It’s the sworn enemies for attack the tank and armored vehicles, also for concrete work.
When launched, the bullet under the action of high temperature and high pressure gas in the chamber, hit a target, it will make a pit. Meanwhile, the bullet will replace the surface of steel armor pit bottom. Although the warhead has burst, but the Projectile under the impact of the strong inertial force, it will continue to forward. When the impact force reaches a certain value, the fuse is triggered, and it caused the explosion of the projectile charge. This would produce dozens of tons to hundreds of tons of high pressure on each square centimeter. Thus, it get the Purpose of destruction.
Now we know, the Penetrator penetrating power mainly comes from the kinetic energy projectile motion.
Tungsten alloy has many excellent characteristics, its high density, good thermal stability, non-toxic, non-polluting, and many other advantages, has been widely used in military category, and gradually replace other military metal.

Tungsten alloy is a kind of free from contamination, abrasion resistant, high hardness of the material. It has good high temperature strength hardness, electrical conductivity and corrosion resistance. So that Tungsten alloy military products are widely used in military field. It is used for the bullet, armor-piercing and warhead, grenades, cannon, tank guns, etcTungsten alloy is a kind of free from contamination, abrasion resistant, high hardness of the material. It has good high temperature strength hardness, electrical conductivity and corrosion resistance. So that Tungsten alloy military products are widely used in military field. It is used for the bullet, armor-piercing and warhead, grenades, cannon, tank guns, etc.
Penetrator is a typical high density tungsten alloy products. Armor-piercing application in the military, is based on the hardness and shape of the shell material, plus a charge transfer of kinetic energy during the shooting, when in contact with the rigid target penetrates the surface and to achieve the effect of damage. Armor-piercing except for anti-tank, can also be used to deal with other solid targets, or use on bomb, the attack warship protective armor.
Early, the shapes of penetrator warhead is simple pointed cone flow line. With the increase of firing distance, simple the firing accuracy of streamlined does not ensure that the warhead. To stabilize the ballistic warheads, began to appear on the warheads hood front end, this kind of penetrator is called cap penetrator. And in World War II began to application.
At present, in order to avoid military material produce pollution to the environment, tungsten alloy military products are gradually replacing lead and depleted uranium for bullets and penetrator.
