High Performance Polishing Heavy Tungsten Alloy Sheet WNiCu

Product Description

High Performance Polishing Heavy Tungsten Alloy Sheet WNiCu

Heavy tungsten alloy sheet is based on tungsten (tungsten content is generally 80% ~ 98%) with a small amount of nickel, iron, copper, cobalt, molybdenum, chromium and other elements of the alloy material. The density of high specific gravity tungsten alloy is 15.20~18.70g/cm3, also known as high specific gravity tungsten alloy or high density alloy material. Because tungsten alloys weigh more than twice as much as iron or steel.

Introduction and characteristics of Heavy Tungsten Alloy Sheet

The high specific gravity tungsten alloys are mainly divided into two series: W-Ni-Fe and W-Ni-Cu, and even W-Ni-Fe-Cu. In contrast, W-Ni-Fe alloy has better mechanical properties. The defense industry and all areas of the national economy play a huge role. It is a very important new military material in the national defense industry and is gradually being popularized in various civil industries.

Tungsten heavy alloy has a series of excellent characteristics, high specific gravity: general specific gravity of 16.5-18.75g/cm3, high strength: tensile strength of 700-1000mpa, strong ray absorption capacity: its capacity is 30-40% higher than lead, large thermal conductivity: 5 times of die steel; Low thermal expansion coefficient: only 1/2-1/3 of steel, good electrical conductivity; Good weldability and machinability.

Application of Heavy Tungsten Alloy Sheet

• Die casting is a kind of precision casting process with less chips and no chips, which can directly manufacture components with complex shapes. Process sheet, high yield, no holes and saving raw materials. Especially in ferrous metal die casting, the working conditions of phase I die are very harsh. It must withstand the scouring of high temperature, high pressure and metal flow, and can resist corrosion, oxidation and thermal shock. High specific gravity tungsten alloy is a good die casting die material because of its good thermal conductivity and corrosion resistance. Compared with copper die, it can improve the service life by tens of times.
