We saw a lot of sophisticated weapons and a number of top military equipments in the parade of Chinese People's War against Japanese Aggression and the World Anti-Fascist victory 70th anniversary in the Tiananmen Square from TV. But in the past China, or any other countries during the war, the weapons could have ability to be used in war are all very simple, but people can always create "surprise" under a difficult circumstance. Grenade is such a surprise. It is one of the common military weapons, which has excellent blasting and lethality, and was firstly used and invented by the Chinese people. It is one of the main weapons of the infantry troops for close combat. Grenade has small size so that can be easily carried. It can be well used for attack and defense, and plays an important role in the last period of relatively simple weapons.

 

Then what aspect can tungsten alloy apply in such “the palm of death"? Actually, the main application of tungsten alloy in grenade is to act as prefabricated fragment for lifting explosion lethality of grenade. Tungsten alloy prefabricated fragment has been widely used in the warhead of various types of weapons, grenade is one of them. Tungsten alloy prefabricated fragment is commonly existed in the form of ball and small blocks, then being attached to the inner surface or the outer surface of a variety of grenades. It would form a more centralized fragment lethality area with the exploration power, so as to hit the enemy and their weapons and equipments. Compared to iron prefabricated fragment, tungsten alloy prefabricated fragment would be more advantage, because tungsten alloy is with high corrosion resistance, wear resistance, and it’s very heavy, so that would be more lethal, which can also greatly prevent the drops of serviceability of grenade caused by iron rusting.
