Heavy Tungsten Alloy Shots plays an important role in weapon manufacturing because of its high density, high strength, high hardness (abbreviation 3H alloy), good ductility, electrical conductivity, thermal conductivity and other comprehensive properties.Subsequently, it has been widely used in the defense industry, aerospace industry and civil industry (such as electrical industry, drilling industry, etc.), and the high-proportion tungsten alloy material has become a military and civilian alloy material.

Tungsten alloy has a series of excellent properties, significant proportion: general specific gravity 16.5-18.75g/cm3, high strength: tensile strength 700-1000mpa, strong light absorption capacity: 30-40% higher than that of lead, large thermal conductivity: 5 times that of mold steel; low thermal expansion coefficient: only 1 / 2-1 / 3 of steel, good electrical conductivity; good soldering and machining.
Tungsten heavy alloys contain 90% to 98% of tungsten, which is responsible for its high density (16.5 to 19.00 g / cc).Nickel, iron, and / or copper are used as a metal adhesive substrate to hold fragile tungsten particles together to make the tungsten alloy firm and easy to use.Ferric nickel is the most commonly used additive with a ratio of 7Ni: 3Fe or 8Ni: 2Fe (by weight).
In order to improve the kinetic energy of the bomb core and improve the armor-piercing ability, the high proportion tungsten alloy is a successful technical measure for the design and development of foreign armor-piercing shells.At present, except for the United States, many countries in Western Europe have used tungsten alloy elastic core material.
