Introduction of Beryllium Copper Alloy No. 3:
C17510 Beryllium copper alloy, also known as alloy 3, gets its
strength from precipitation heat treating. The grade of the C17510
material has a very high yield-strength-to- conductivity ratio and
is good for moderate stress applications where galling is a
concern. C17510(Alloy 3) is used mainly in aerospace and plastic
mold tooling industries, this product is ideal for small electronic
connector and mold tooling applications including pylon bushings
for large turbine engines, conductors, relay parts, and roll pins.

Weldability
Soldering, brazing, gas shielded arc welding, coated metal arc
welding, spot welding, seam welding and butt welding are all
recommended
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.
