Product Informance of CUBERYLLIUM® Company:

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.

CUBERYLLIUM ®-170 also named Cube1.7-C17000 (CDA 170) Beryllium Copper is a lightly alloyed grade of copper, formulated for primary forming into wrought products. CW100C is the EN numeric designation for this material. Alloy170 is the UNS number. Additionally, the EN chemical designation is CuBe1,7. And the British Standard (BS) designation is CB101. Older literature may refer to this material as ASTM Alloy 165, 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 a moderately low thermal conductivity.

The properties of Alloy170 copper include fourteen common variations. This page shows summary ranges across all of them. For more specific values, follow the links immediately below. The graph bars on the material properties cards further below compare Alloy 170 copper to: wrought coppers (top), all copper alloys (middle), and the entire database (bottom). A full bar means this is the highest value in the relevant set. A half-full bar means it's 50% of the highest, and so on.

Welding methods such as soldering, brazing, gas shielded arc welding, coated metal arc welding, spot welding, seam welding and butt welding are preferred for C17000 copper alloys. Oxyacetylene welding is not recommended for this type of alloys.

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 CuBe1.7 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 Cuberyllium.

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.
