Product Description

Tungsten-copper alloy
The tungsten-copper alloy is a composite material containing tungsten and copper, combining tungsten's high melting point and hardness with copper's excellent electrical and thermal conductivity. Its main features and applications are as follows:

High melting point: Tungsten's melting point of 3,422°C makes the tungsten-copper alloy suitable for high-temperature environments.

High density: the high density of tungsten makes tungsten-copper alloys suitable for applications requiring a high mass per unit volume.

Excellent electrical conductivity: copper's superior conductivity makes it widely used in electronics and electrical engineering.

Superior thermal conductivity: copper's excellent thermal conductivity makes it ideal for applications that require high heat dissipation.

Wear resistance: the high hardness of tungsten gives the alloy excellent wear resistance.

Applications
Electronics industry: they are used in electrodes, contacts, heat sinks, and more.

Aerospace: they are used in high-temperature components and thermal management systems.

Defense industry: they are used in materials requiring high density and strength, such as armor-piercing projectiles.

Manufacturing machinery: they are used in wear-resistant components and high-temperature molds.

Medical equipment: used in X-ray tubes, among other applications.

Manufacturing processes
Powder metallurgy: Mixing tungsten powder with copper powder, followed by pressing to shape and sintering.

Infusion process: Preparation of a porous tungsten skeleton into which copper is infused.

A 70% tungsten-copper bar refers to a tungsten-copper alloy material containing 70% tungsten and 30% copper. This alloy combines tungsten's high melting point and hardness with copper's excellent electrical and thermal conductivity, enabling it to be widely used across multiple industries.
