WNiFe / WNiCu Tungsten Heavy Alloy Plate With Good Electrical Conductivity

• 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 brittletungsten 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 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.
