HIGH STRENGTH, MILL HARDENED STRIP ALLOYS FOR AUTOMOTIVE AND ELECTRONICS APPLICATIONS
Components used in automotive and consumer electronics applications need to be made from high strength materials that can withstand the harsh operating environment. Materion’s high strength, mill hardened copper beryllium (UNS C17200) strip materials, Alloy 190 and Alloy 290, provide the highest strength of any mill hardened copper alloy, combined with electrical conductivity considerably greater than other high strength copper alloys.
ALLOY 190 FOR PRECISION STRIP APPLICATIONS
Alloy 190 is an outstanding strip material for making automotive terminals, components for medical connectors, battery contacts and contacts for switches and relays. When compared with Alloy 290, Alloy 190 is flatter and better for precision strip applications and operations like photochemical machining that are sensitive to shape. Alloy 190 does not require heat treatment and offers tensile strength up to 190 ksi (1310 MPa).
Our copper beryllium alloys adhere to international specifications so that you can easily integrate them into existing designs or meet required standards. Cube Alloy 190 strip is specified to the following standards:
- ASTM B194, ASTM B888
- EN 1652, EN 1654, EN 14436
- JIS H3130

ALLOY 290 FOR HIGH STRENGTH, HIGH RELIABILITY COMPONENTS
Alloy 290 has greater formability than Alloy 190, making it an ideal material for board-to-board contacts, spring contacts for batteries and audio jack contacts. It is most often used to fabricate high reliability components that require complicated connections without losing strength. Alloy 290 also has 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 a cost-effective alternative to conventional mill hardened products.
CuBe Alloy 290 strip is specified in ASTM B194 and ASTM B888 standards.
