Application of High-density Tungsten Alloy in the Electrical Processing Industry

Due to the high density tungsten alloy with good electrical properties and are widely used in the electrical processing industry

An electric riveting machine riveting head material

In electric riveting process, rivets temperatures up to 1000 ℃, but also to withstand the impact of the role of the arc ablation, high-density tungsten alloy of various metal rivets riveting has the following advantages:

1. The life of common materials than in the past rivet head up a few dozen to more than a hundred times;

2. Good quality, smooth and can not afford the rivet head pitting,

3. Convenient punch processing, high-speed steel to be heat treated alloy must EDM, high-density tungsten alloy can be used as long as the vehicle processing

High-density tungsten alloy is a class of tungsten-based (tungsten quality score is usually 80% to 97%), and added alloy Ni, Fe, Co, Cu, Mo, Cr and other elements, and its density as high as 16.5 to 19.0 g / cm3, and been known as high-density tungsten alloy, heavy alloy, heavy alloy. Not only high-density tungsten alloy density, but also has a series of excellent performance: high strength, high hardness, ductility, good machining properties, thermal expansion coefficient, thermal conductivity, anti-oxidation and good corrosion resistance, weldability good and so on. The excellent performance has been widely applied in the field of cutting-edge science, military, industrial and civilian industry. So far, W-Ni-Fe, W-Ni-Cu alloy has become a high-density tungsten alloy two major series.
