Product Informance of CUBERYLLIUM® Company:

CUBERYLLIUM® manufactures copper beryllium in several distinct compositions.

These fall into two categories: high strength beryllium copper alloys 172(UNS. C17200),173(UNS. C17300),170(UNS. C17000), and copper alloys selected for high conductivity 751(UNS. 17510),750(UNS. 17500),741(UNS. 17410).

We also Supply Master alloy : CuBeryllium-200, CuBeryllium-275, CuBeryllium-350 and Cuberyllium-400 to global factory.

Introduction Of C17200(CDA 172) Beryllium Bronze Alloy:

C17200 copper is a lightly alloyed grade of copper, formulated for primary forming into wrought products. CW101C is the EN numeric designation for this material. C17200 is the UNS number. Additionally, the EN chemical designation is CuBe2. Older literature may refer to this material as ASTM Alloy 25, but this is now discouraged.

It has a moderately low electrical conductivity among wrought coppers. In addition, it has a moderately low melting temperature and can have a moderately high tensile strength.

The most important Technology of CUBERYLLIUM ®

A: Heat treatment

Heat treatment is the most important process for this alloy system. While all copper alloys are hardenable by cold working, beryllium copper is unique in being hardenable by a simple low temperature thermal treatment. It involves two basic steps. The first is called solution annealing and the second, precipitation or age hardening.

B: Solution Annealing

For the typical alloy CuBe1.9 (1.8- 2%) the alloy is heated between 720°C and 860°C. At this point the contained beryllium is essentially “dissolved” in the copper matrix (alpha phase). By rapidly quenching to room temperature this solid solution structure is retained. The material at this stage is very soft and ductile and can be readily cold worked by drawing, forming rolling, or cold heading. The solution annealing operation is part of the process at the mill and is not typically used by the customer. Temperature, time at temperature, quench rate, grain size, and hardness are all very critical parameters and are tightly controlled by ohmalloy.

C: 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.
