Bronze БрК3Мц1 (Brkmc3-1)
Designation
Description
Bronze БрК3Мц1 used: for the manufacture of semi-finished products (strips, bands, bars and wire); parts of all kinds for chemical apparatus; springs and spring parts; parts for shipbuilding; welded structures; round welding wire and welding rods round drawn and extruded with a diameter of from 1.2 to 8.0 mm, designed for manual welding in shielding gases, non-rigid structures made of copper and automatic copper welding under flux.
Note
Corrosion resistant silicon-manganese heat resisting bronze, is suitable for welding and has high resistance to compression.
Analogue of bronze Brkmc3−1 (БрК3Мц1) at CMEA 377−76 is bronze CuSi3Mn1.
Standards
Chemical composition
Cu is the basis.
According to GOST 18175-78, the total mass fraction of normalized impurities is ≤ 1.0%. According to the manufacturer's agreement with the consumer, up to 2.0% of iron is allowed without taking it into account in the total amount of impurities, and also the content of impurities of arsenic, antimony and phosphorus can be normalized.
