CUBERYLLIUM® is one of the beryllium copper alloys suppliers in China. We could provide all types of copper alloys, like beryllium copper rods, beryllium copper wires, beryllium copper tube, beryllium copper stirp and so on. The grades includes C17200, C17300, C17510, C17500, C17000 and C17410.

The principle characteristics of alloy 172 are an excellent response to precipitation-hardening treatments, excellent thermal conductivity, and resistance to stress relaxation. The high strength beryllium coppers C172 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 maximum strength and hardness. 

C17200 also commonly known as Alloy 25, is available in round rod, bar, tube, and strip.

Key Technology of Beryllium Copper(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.

Solution Annealing

For the typical alloy CuBe2Pb) 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.

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.
