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. Tungsten alloy ring could be used for weight such as aircraft weight, automobile weight, clock weight, mobile phone vibrator weight. In the miliary field used as kinetic energy armor piercing material, prefabricated fragment material, etc.
