Copper beryllium (CuBe) alloys offer a unique combination of strength, conductivity, hardness and corrosion resistance and are non-magnetic and spark resistant. 

CuBe materials are successfully used in: Aerospace and Defense Automotive  | Consumer Electronics | Industrial | Oil and Gas | Telecom and Server

Copper beryllium offers many benefits, including the greatest strength of all copper-based alloys (up to 1,400 MPa / 200,000 psi), conductivity that maintains the flow of electrical and thermal energy, improved miniaturization that allows smaller parts and connectors that have high a repetitive cycle life and can be formed into complex shapes. It has excellent stress relaxation to retain contact force at elevated temperatures and durability that resists wear, corrosion and galling.

Materion manufactures copper beryllium rod, bar, wire, tube, plate, strip, forgings, and extrusions in several distinct compositions to meet specific property requirements. See below how each of our copper beryllium alloys can enable and enhance your end-use applications.
