The Advantages of Tungsten Nickel-iron Alloy Military Blasting Ring

Tungsten nickel alloy gravity is generally 17.0 to 18.5, a tungsten-based (about 90 to 98 percent), and add nickel, iron, copper or other elements of the alloy composition. This alloy has good plasticity, machinability, thermal conductivity and electrical conductivity, while the X-rays or γ-rays with excellent absorption capacity. Because of this characteristic tungsten nickel-iron alloy, and it is often used in the manufacture of military blasting ring.

Advantages tungsten nickel-iron alloy military blasting ring are: a large proportion: General accounting for 16.5-18.75g / cm3; 2 high strength: tensile strength of 700-1000Mpa; 3 ray absorption ability: than lead high 30 -40%; 4 thermal coefficient: thermal conductivity of tungsten alloy tool steel is 5 times; five thermal expansion coefficient is small: only 1 / 2-1 / 3 iron or steel.
