BrB2 alloys belong to the tinless type bronze material, which is processed by high pressure. They are produced in accordance with GOST 18175-78 standards and can also be called beryllium bronze. The alloys contain at least 96.9% pure copper and about 2% beryllium. Nickel and other impurities are also present.
Rolled bronze based on alloy c17200/din 2.1447/brb2 differs in excellent operational parameters and physical characteristics. It is wear resistant and virtually immune to any known type of corrosion.
The alloy has pronounced anti-friction and spring properties, thermal conductivity and electrical conductivity is not very high. It is possible to improve individual mechanical parameters – for this, a special technology of hardening and forced aging is used
Range and application
BrB2 brand alloys are used in the production of such rolled metal products as:
bronze pipe ,
bronze ribbon and stripe,
bronze rod,
bronze wire,
bronze circle,
bronze bushings and more.
Mainly used for the production of springs and spring elements in various mechanisms. The most wear-resistant parts and non-sparking tools are made from the alloy.
