CUBERYLLIUM® manufactures copper beryllium in several distinct compositions. These fall into two categories: alloys selected for high strength (Alloys 172,173,170) and alloys selected for high conductivity (Alloys 751,750,741). And Gost standard QBe2,QBe1.9Ti for Russia Market. Also Supply Master alloy : CuBeryllium-200; CuBeryllium-275);CuBeryllium-350 and Cuberyllium-400 to global factory.


Introduction of C17500 Alloy:

Alloy c17500 bars has a Chemical Formula of BeCu. Beryllium copper goes by various names and these are beryllium bronze, copper beryllium (CuBe) and spring copper. C17500 has moderate strength and its conductivity is around 50% IACS. Copper that is of the c17500 beryllium variety, is used in a wide variety of industrial processes in resistance welding equipment, switch parts, spring connectors, fasteners, fuse clips, die–casting plunger tips, springs, resistance and spot welding tips, connectors, seam welding dies, relay parts, tooling for plastic moulds, washers, etc. It is available in sheets, round tubes, rectangular bars, flat bars, round wires, coils, square bars, plates, round bars, hexagon bars and various custom made shapes.

Hot & Cold Workability

Good hot working properties. Excellent cold working properties.


Key Technology of Beryllium Copper(Heat treatment)

Age Hardening

Age hardening significantly enhances the material’s strength. This reaction is generally carried out at temperatures between 260°C and 540°C depending on alloy and desired characteristics. This cycle causes the dissolved beryllium to precipitate as a beryllium rich (gamma) phase in the matrix and at the grain boundaries. It is the formation of this precipitate which causes the large increase in material strength. The level of mechanical properties attained is determined by the temperature and time at temperature. It should be recognized that beryllium copper has no room temperature aging characteristics.
