Tungsten Heavy Alloy Fishing Weight

Product Description

Introduction of Tungsten Alloy Balls (sphere)
Tungsten heavy alloys are usually consisted of W-Ni- Fe or W-Ni- Cu or even W-Ni-Cu-Fe, some tungsten alloy is added Co, Mo, Cr, etc. It could be made as many shapes. Tungsten alloy ball is in small volume with high density, which means it could be used in some fields need the little but heavy parts
