Materion Alloy 390E Copper Beryllium Strip
Categories:	Metal; Nonferrous Metal; Beryllium Alloy; Copper Alloy
Material Notes:	Alloy 390E is a copper beryllium alloy that provides a unique combination of high strength, high electrical conductivity, and excellent formability. Copper beryllium alloys are well known for their superior stress relaxation resistance and fatigue strength. This allows engineers the flexibility to design small form factor signal and power interconnects that can be used in harsh environments. Information supplied by Materion.
