As a common copper alloy product in our daily life, tungsten-copper alloy is widely used in various industries. The tungsten-copper and tungsten-copper alloy products produced by Hongma Copper are not only of high quality, but also recognized by the majority of demanders. .

Properties of tungsten copper alloy

Tungsten copper alloy is an alloy composed of tungsten and copper. Commonly used alloys contain 10% to 50% copper. The alloy is prepared by powder metallurgy, which has good electrical and thermal conductivity, good high temperature strength and certain plasticity. At very high temperatures, such as above 3000°C, the copper in the alloy is liquefied and evaporated, absorbing a large amount of heat and reducing the surface temperature of the material. So this kind of material is also called metal sweating material.

Tungsten Copper Alloy Process Introduction

Tungsten copper is formed by isostatic pressing-high temperature sintered tungsten skeleton-copper infiltration process. It is an alloy of tungsten and copper.

The process of preparing tungsten-copper alloy by powder metallurgy is powder-making-batching mixing-pressing forming-sintering infiltration-cold working.

Tungsten Copper Application:

1. Electrode material: used in high-hardness materials and pu-chip electrode electric discharge machining, the surface of the electro-processed product has high surface finish, high precision, low loss and effective saving.

2. Contact materials: arc contacts and vacuum contacts of high and medium voltage switches or circuit breakers, circuit board welding and electrical contact points.

3. Welding materials: submerged arc welding machine, gas shielded welding machine nozzle, radio resistance factory (production of carbon film resistance, metal coating resistance) resistance butt welding machine butt welding material (copper-tungsten alloy welding disc)

4. Guiding and guarding materials: all kinds of wire rolled steel, used for guiding and protecting materials.

Uses of tungsten copper alloy

Tungsten-copper alloy has a wide range of uses, mainly used to manufacture high-temperature components such as the contacts of high-voltage electrical switches that resist arc ablation, rocket nozzle throat linings, and tail rudders, as well as electrodes for electrical machining, high-temperature molds and other Applications requiring electrical and thermal conductivity and high temperature use.

Using high-quality tungsten powder and oxygen-free copper powder, applying isostatic pressing (high temperature sintering-copper infiltration) to ensure product purity and accurate proportioning, fine structure, and excellent performance. Good arc breaking performance, good electrical conductivity, and good thermal conductivity , Thermal expansion is small.
