Material properties
Tough construction material with good sliding properties; insensitive to impact and shock; high corrosion resistance to neutral, basic and aqueous acidic media as well as seawater, high resistance to cavitation; low permeability (close to 1 H)
Application examples
Drive parts, impellers, gear wheels, thrust pieces, plain bearings with high static or dynamic loads, worm gears, valve guides, screws and nuts for corrosion applications, fittings; components in the chemical industry or in use with seawater (marine)
Processing
Easy to machine, use of carbide tools recommended, good weldability (filler materials based on CuAl or NiAl), brazing possible, good polishability
