Application of Tungsten Alloy in Military Industry

New materials, also called advanced materials, refer to a kind of new materials which have excellent features and functions, and can satisfy the need of high technology. Military new material is used in the field of military, and is the key to make weapons and equipment better. While the military new materials technology is used in the military field of new materials technology, is the key to the modern weapon equipment. Tungsten has the highest melting point in the metal, and its outstanding advantage is high melting point with good high temperature strength and corrosion resistance, the military industry especially show the characteristics of the excellent weapons manufacturing. In the ordnance industry it is used mainly for a variety of penetrator warhead, main battle tank penetrator with large length to diameter ratio, small and medium caliber anti-aircraft penetrator and hypervelocity kinetic energy penetrator with elastic core material.

Tungsten alloy powder through pretreatment technology and large deformation strengthening technology, refining grain materials, elongated grain orientation, improving the strong toughness of the material and the penetration power. Developed by our country main battle tank type 125 Ⅱ penetrator tungsten core materials for W - Ni - Fe, the variable density compact sintering process, the average performance of tensile strength of 1.2 billion mpa, the elongation of 15% above, vowing index is 2000 m distance breakdown 2000 mm thick homogeneous steel armor.
