Comprehensive Applications of Tungsten-Copper Alloy in Aerospace and New Energy Vehicles

Tungsten-Copper Alloy (CuW80): A Core Material for Aerospace and New Energy

In the new materials sector, one alloy, tungsten-copper alloy (CuW80), is attracting increasing attention from companies due to its advantages such as high-temperature resistance, strong conductivity, and corrosion resistance.

With the rapid development of the aerospace, new energy vehicle, and high-end electronics industries, this material is taking center stage in the market.

What is Tungsten-Copper Alloy (CuW80)?

Tungsten-copper alloy is a composite material created through powder metallurgy by combining high-melting-point tungsten with highly conductive copper.

CuW80 indicates a tungsten content of approximately 80% and a copper content of 20%.

This ratio combines the high melting point, high hardness, and ablation resistance of tungsten with the high thermal and electrical conductivity of copper.

This combination of rigidity and flexibility allows it to perform stably in a variety of extreme operating conditions.

CuW80’s Core Performance Advantages:

High-Temperature Stability: It maintains structural strength above 2000°C and is widely used in high-temperature environments.

Excellent electrical and thermal conductivity: Ensures outstanding performance in EDM, electrical contacts, and heat dissipation components.

Oxidation and corrosion resistance: Enables long-term stable service under complex operating conditions.

High strength and wear resistance: Suitable for manufacturing key components such as electrode blocks and switch contacts.

These properties make CuW80 not just a material but also a strategic pillar of advanced manufacturing.

Applications of CuW80 tungsten-copper alloy

Aerospace: Rocket nozzle linings and ablation-resistant components for spacecraft, ensuring stable operation under extreme temperatures.

New Energy Industry: Heat dissipation substrates for IGBT modules in new energy vehicles, improving the safety of electronic control systems.

Electrical and electronic equipment: Significantly extends the life of arc contacts in high-voltage switches and vacuum switch contacts.

Molds and precision manufacturing: EDM electrodes and mold heat dissipation structures improve processing efficiency and product quality.

It can be said that CuW80 will be present in almost all of the highly prosperous industrial chains of the next decade, from aerospace to new energy to electronics and electrical.

Why is CuW80 so promising?

The world is ushering in a new era of new energy and aerospace:

New energy vehicle sales have been climbing year after year, spurring a surge in demand for high-temperature heat-dissipating alloys;

Frequent domestic large aircraft and rocket launches require a large amount of ablation-resistant materials;

The electronics and chip industries are experiencing rapid iteration, and their reliance on high-performance heat-dissipating materials continues to grow.

Tungsten-copper alloy (CuW80) addresses these pain points. It not only meets the demands for stability in extreme environments but also helps companies improve product lifespan and safety. Therefore, it is considered a strategic material with great potential for the next decade.

Procurement and Market Value

Currently, CuW80 is primarily available in the form of sheets, bars, and electrode blocks. When selecting CuW80, buyers often prioritize the following:

Density (close to theoretical density, ensuring stable performance);

Hardness (≥HB200, meeting wear resistance requirements);

Conductivity (≥30% IACS, ensuring electrical performance);

Ablation resistance life (several times better than ordinary copper alloys).

With the expansion of downstream industries, market demand for CuW80 is expected to continue to grow, making it an indispensable material for high-end manufacturing.
