High Density WNiFe Heavy Heavy Tungsten Alloy Balls For Shotgun
Shots
Heavy Tungsten Alloy Balls play an important role in weapon
manufacturing because of its high density, high strength, high
hardness (3H alloy for short), good ductility, conductivity,
thermal conductivity and other comprehensive properties. Then it is
widely used in national defense industry, aerospace and civil
industry (such as electrical industry, drilling industry, etc.),
and high specific gravity tungsten alloy material has become a kind
of military and civil alloy material.

Heavy Tungsten Alloy Balls Picture:
What is the Heavy Tungsten Alloy Balls?
Tungsten alloy has a series of excellent properties, the specific
gravity is significant: general specific gravity of
16.5-18.75g/cm3, high strength: tensile strength of 700-1000mpa,
strong light absorption capacity: 30-40% higher than the specific
capacity of lead, large thermal conductivity: 5 times of die steel;
Low thermal expansion coefficient: only 1/2-1/3 of steel, good
electrical conductivity; Good weldability and machinability.
Tungsten heavy alloys contain 90% to 98% tungsten, which is
responsible for their high density (16.5 to 19.00 g/cc). Nickel,
iron and/or copper are used as metal binder bases to hold fragile
tungsten particles together, making tungsten alloys strong and easy
to work with. Ferric nickel Nickel is the most commonly used
additive with a ratio of 7Ni:3Fe or 8Ni:2Fe (by weight).
Application of Heavy Tungsten Alloy Balls
In view of the above excellent functions of high specific gravity
alloy, it is widely used in aerospace, aviation, military, oil
drilling, electrical instruments, medicine and other industries.
- Application in aerospace, missile and aviation industry
