Product Description

Technical details, material information and manufacturing notes for this product.

Tungsten copper rods are precision-engineered composite materials designed for high-performance industrial applications.

They combine tungsten’s high melting point with copper’s superior conductivity and thermal stability.

Manufactured using powder metallurgy and infiltration technology, they offer uniform density and low porosity.

These rods are widely used in EDM machining, electrical contact systems, and aerospace thermal components.

They provide excellent arc resistance, wear resistance, and dimensional stability under extreme conditions.

Available in multiple grades, tungsten copper rods ensure reliable performance in high-voltage and high-temperature environments.

Buyers choose the grade based on conductivity vs heat resistance requirements.
