Why choose ABRAFIL CuAl8?

  • Excellent corrosion resistance, even in seawater:
    ABRAFIL CuAl8 forms a protective alumina layer that makes it highly resistant to oxidation, salt water and aggressive industrial atmospheres. It is the alloy of choice for marine and chemical applications.

  • Excellent mechanical and erosion resistance:
    Thanks to its dense, tough structure, the deposited metal is highly resistant to impact, abrasion and erosion, prolonging the life of parts, even under severe conditions.

  • Excellent weldability of aluminum bronzes:
    ABRAFIL CuAl8 is the standard wire for welding or hardfacing aluminum bronzes (CuAl8Fe, CuAl9Mn2, etc.), with a stable bath, low spatter and good melting quality.

  • Marine, hydraulic and mechanical applications:
    Used for welding propellers, valves, pumps, valve bodies, bushings, bearings, fittings or piping components subject to chemical and mechanical stress.

  • Good compromise between ductility and strength:
    The deposit remains relatively ductile despite its strength, enabling it to absorb vibrations and mechanical stresses without premature cracking.
