Material Performance: Copper’s Unique Advantages

Copper is the material of choice for high-performance industrial components, and our parts maximize its benefits:

1. Superior Electrical Conductivity: With conductivity exceeding 100% IACS, our copper parts minimize electrical resistance, reducing power loss in busbars, connectors, and RF waveguides. This makes them ideal for high-frequency and high-current applications where signal integrity is paramount.

​

2. Exceptional Thermal Conductivity: Copper’s high thermal conductivity allows for rapid heat dissipation, making these parts perfect for heat sinks, cooling plates, and thermal management systems in servers, power supplies, and industrial machinery.

​

3. Ductility & Formability: Pure copper is highly ductile, allowing us to machine intricate, thin-walled structures without cracking or warping, even in complex 5-axis geometries.

​

4. Corrosion Resistance: Copper naturally resists corrosion in most industrial environments, and with optional plating, parts can withstand harsh chemical and outdoor conditions for extended periods.
