Home Products High Performance Alloys Copper Beryllium Alloys Alloy 190, 290 HIGH STRENGTH, MILL HARDENED STRIP ALLOYS Alloy 190 / Alloy 290 Materion’s Alloy 190 and Alloy 290 (UNS C17200) offer many advantages when building components that require high strength. These copper beryllium (CuBe) strip alloys provide the highest strength of any mill hardened copper alloy, and they offer electrical conductivity considerably greater than other high strength copper alloys. Alloy 190 is flatter and better for precision strip applications that cannot have deviations in the materials. Alloy 190 does not require heat treatment and offers tensile strength up to 190 ksi. Alloy 290 has all the strength of Alloy 190, but offers improved formability, allowing it to be bent and reformed into specially shaped electrical connectors and contact points. Alloy 290 is used to fabricate high reliability components that require complicated connections without losing strength. The unique combination of strength and formability of Alloy 290 makes it a cost- effective alternative to conventional mill hardened products. APPLICATIONS FOR ALLOY 190 & ALLOY 290 Alloy 190 is an outstanding material for making automotive terminals, battery contacts and contacts for switches and relays. Alloy 290 has greater formability, making it an ideal material for board-to-board contacts, spring contacts for batteries and audio jack contacts.
