What Is Iron Copper Alloy (Fe-Cu Alloy)?

High Performance Iron Copper Composite Materials for Powder Metallurgy, Automotive and Industrial Applications

Iron Copper Alloy (Fe-Cu Alloy) is a composite metallic material combining iron and copper to achieve improved mechanical strength, thermal conductivity and electrical performance.

Unlike traditional copper alloys, Fe-Cu alloys are commonly produced through powder metallurgy, sintering or copper infiltration processes. The addition of copper improves dimensional stability, conductivity and wear resistance of iron-based materials.

Sunny Steel supplies iron copper alloy materials and customized components for automotive, electrical, mechanical and industrial applications requiring a balance between strength and conductivity.
