Description

Bronze БрА9Мц2 used: for the manufacture of hot rolled and cold rolled strip; pipe; tube plates of condensers; wear-resistant parts, propellers and shafts; parts of hydraulic installations; wear-resistant parts with high anti-corrosion properties; round welding wire and welding rods round drawn and extruded with a diameter of from 2.0 to 8.0 mm, designed for manual welding in shielding gases aluminum-manganese bronze, ARSENICAL brass, copper and copper-Nickel alloy and aluminum-manganese bronze, as well as for manual and mechanized welding for steel.

Note

Bronze has a high resistance to alternating loads.
Analogue of bronze Bramc9−2 at the CMEA 377−76 is bronze CuAl9Mn2.

According to GOST 18175-78, the total mass fraction of standardized impurities is ≤ 1.50%. As agreed by the manufacturer with the consumer, the content of impurities of arsenic and antimony can be normalized. The mass fraction of nickel is allowed up to 0.50% without taking it into account in the total amount of impurities.
