CUBERYLLIUM® maintains an inventory of beryllium copper alloys, including
beryllium copper strips, beryllium copper rods/bars, beryllium
copper wires and so on.
The normal grades of beryllium copper alloy are C17200 and C17300,
with high strength and moderate conductivity. C17200 & C17300 can
be purchased in the solution annealed or cold worked tempers and
can be easily formed or machined. A low-temperature heat treatment
(600 degrees for 2-3 hours ) produces additional maximum strenght
and hardness.
The Features of Beryllium Copper Alloy M25, C17300, Cube2Pb:
1, Free-Machining Beryllium
2, Used when formation of small chips during machining is desirable
3, Same mechanical & physical properties of alloy 172 (C17200)
Chemical Composition of C17300(CuBe2Pb) Beryllium Copper Alloys:

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.
We could provide rods/bars according to your specifications.
