Tungsten Heavy Alloy Plate

Tungsten Heavy Alloys

Description

Tungsten heavy alloys are generally refractory metal, which have two-phase composites consisting of W-Ni- Fe or W-Ni- Cu or even W-Ni-Cu-Fe, some tungsten alloy is added with Co、Mo、Cr, etc. They have very high melting point and have a density twice that of steel and are more than 50% heavier than lead. Tungsten content in conventional heavy alloys varies from 90 to 98 weight percent and is the reason for their high density (between 16.5 and 18.75 g/cc). Nickel, iron and copper serve as a binder matrix, which holds the brittle tungsten grains together and makes the alloys ductile and easy to machine.

Advantages

●High density (16.5~18.75 g/ cm3)

●High tensile strength (700-1000Mpa)

●Good electrical conductivity

●Low thermal expansion

●Good corrosion resistance

●Good weldablity

●Good machinability

●High absorption capacity against X-rays and γ rays, 30-40% higher than lead

●Harmless to health and environment

●Non-magnetic, if specifically required

The above advantages have made this alloy a candidate for defense and civilian applications. They are widely used in many fields such as aerospace, military, oil logging, electrical appliance, medical, etc.
