Product Description

Product Description

Introduction

Tungsten heavy alloy  is 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. For instance, it could be used as fishing weight, ballast, decorative balls, automatic oil seal valves and shotgun shells. As the same time, it can also be applied to the military field as prefabricated fragments and other purposes. As a professional manufacturer with years of experience, we can offer tungsten alloy balls of various grades and sizes. Each process is strictly required to ensure that the products strictly comply with your requirements.
