17~18.5 G/Cm3 Tungsten Heavy Alloy Tungsten Nickel Copper Alloy

Tungsten Nickel Copper Alloy Tungsten Heavy Alloy

Tungsten Nickel Copper Alloy is made of tungsten, nickel, copper and other chemical elements in appropriate proportions. The alloy mainly contains more than 85% tungsten and a small amount of nickel and copper. The ratio of nickel to copper added is usually 3:2. WNiCu alloy is produced by processes such as liquid phase sintering and additive element alloying. Due to the different characteristics and uses of the alloy, the main components can be divided into W-Ni-Fe, W-Ni-Cu, W-Co, W-WC-Cu, W-Ag, etc. series

Tungsten Nickel Copper Alloy Features:

Tungsten nickel copper (W-Ni-Cu) high density alloy

High density (17-18.75 g/cm3)

High melting point

Good corrosion and oxidation resistance

High tensile strength (700-1000Mpa), good elongation

Good plasticity and workability

Good thermal and electrical conductivity

Low vapor pressure, good thermal stability, small thermal expansion coefficient

Good workability and solderability

Strong radiation absorption capacity (30-40% higher than lead), strong absorption capacity for γ-rays or x-rays

Because their specific gravity is greater than 17 or higher, they are often referred to as tungsten-based high specific gravity alloys.
