CUBERYLLIUM® is specialized in producing beryllium copper alloys, including
beryllium copper strips/ tapes, beryllium copper rods/bars,
beryllium copper tubes, beryllium copper wires, beryllium copper
plates, beryllium copper billets, with high quality performance
metals for electrical industry fasteners and industrial.
The grades could be C17200. C17300, C17500, C17510.
C17200(CU-BE Alloy 25) is manufactured to provide a combination of high strength and
hardness properties coupled with superior thermal properties. This
range of properties makes C17200 the premier material for copper
alloy molds and a wide range of other applications from oil and gas
to aerospace.
