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(БрБ2;БрБНТ1.9) for Russia Market. Also Supply Master alloy: CuBeryllium-200; CuBeryllium-275);CuBeryllium-350 and Cuberyllium-400 to global factory.


CUBERYLLIUM ®-Qbe2 also named CuBe2 Beryllium Copper, is the most commonly utilized copper beryllium alloy and is notable for its highest strength and hardness compared to commercial copper alloys. Qbe2 beryllium bronze contains a small amount of nickel, which is a high-performance copper alloy with good mechanical, physical and chemical comprehensive properties; after solid solution and time hardening treatment(quenching and tempering), it has high strength, hardness, corrosion resistance, elasticity and wear resistance, explosion resistance, heat resistance, yield and fatigue limit; at the same time, it also has high electrical conductivity, thermal conductivity and cold resistance, non-magnetic, no sparks when hit, easy to process, easy to weld and braze, excellent cooling effect, excellent corrosion resistance in air, fresh water and sea water.

Qbe2 alloy contains appr. 2% of beryllium and achieves its ultimate tensile strength can exceed 1360Mpa, while the hardness approaches Rockwell C45. Meanwhile, the electrical conductivity is a minimum of 22% IACS in the fully aged condition.

  • "A' represents the state of solution annealing (annealed, the alloy is in the softest state, easy to be stamped and formed, and needs to be cold worked or strengthened during the direct failure period);
  • "H" stands for cold processing state (Hard);
  • "T" means that the meterial has been aging hardened by standard heat treatment (heat treatment means the state of aging strengthening heat treatment).


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.
