CUBERYLLIUM®-172 is the most commonly specified copper beryllium ,In its age
hardened condition, CUBERYLLIUM®-172 attains the highest strength
and hardness of any commercial copper base alloy. The ultimate
tensile strength can exceed 1360Mpa(200 ksi), while the hardness
approaches Rockwell C45. Also, in the fully aged condition, the
electrical conductivity is a minimum of 22% IACS (International
Annealed Copper Standard). Alloy 172 also exhibits exceptional
resistance to stress relaxation at elevated temperatures.
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.
