CUBERYLLIUM® manufactures copper beryllium in several distinct compositions. These fall into two categories: alloys selected for high strength (Alloys 172,173,170) and alloys selected for high conductivity (Alloys 751,750,741). And Gost standard QBe2,QBe1.9Ti for Russia Market. Also Supply Master alloy : CuBeryllium-200; CuBeryllium-275);CuBeryllium-350 and Cuberyllium-400 to global factory.

Features and Application of C17300 (CDA 173) Beryllium Copper Alloy:

CUBERYLLIUM ®-173 also named -C17300 (CDA 173). C17300 rod and wire contain a small amount of lead to provide an alloy tailored for automatic machining operations.

C17300 free-cutting beryllium bronze has good processing performance, high thermal conductivity, weldability, corrosion resistance, polishability, wear resistance, adhesion resistance, and can be forged into various shapes of parts, and its strength and wear resistance ratio Chromium-zirconium copper alloy has better physical properties and is used in medium-strength and high-conductivity parts, such as: fuse fasteners, springs, connectors, resistance spot welding heads, seam welding rollers, die-casting machine die heads, plastic molding dies, Probes, coaxial connectors, photomultiplier tubes, high-precision instruments, military aerospace, etc.

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.
