High Density WNiFe Heavy Tungsten Alloy Shots For Shotgun ShellHeavy 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. Heavy Tungsten Alloy Shots SPECIFICATION :| Chemical Composition | 90%W | 93%W | 95%W | 97%W | | | | | | | | State | Sinter | Vacuum | Forge | Sinter | Vacuum | Forge | Sinter | Vacuum | Sinter | Vacuum | Density

Heavy Tungsten Alloy Shots Picture:
What is the Heavy Tungsten Alloy Shots?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).
Application of Heavy Tungsten Alloy ShotsIn 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.
