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.
