Tungsten Bar-rod

W90nife W92.5 W93 W95 W97 Tungsten Heavy Alloy Rod Bar

More Info

Tungsten alloy generally has two-phase composites consisting of W-Ni-Fe or W-Ni- Cu or even W-Ni-Cu-Fe, some tungsten alloy is added Co、Mo、Cr, etc. Tungsten content in conventional heavy alloys varies from 90% to 97% and is the reason for their high density (between 16.5g/cc and 18.75 g/cc). 
It could be made as various shapes,such as rod,ball,cylinder,brick,ring,etc.
