CuAl8Ni2 Thermal Spray Wire - Wear Resistant & Corrosion Resistant Aluminum Bronze Spray Wire with 8% Al + 2% Ni Alloy
Product Description
CuAl8Ni2 thermal spray wire is an aluminum bronze alloy containing approximately 8% aluminum and 2% nickel. It is designed for arc spray and flame spray processes, producing dense, wear-resistant, corrosion-resistant coatings with strong adhesion and long service life.
Compared with CuAl7 or CuAl8, this alloy provides higher hardness, better load-bearing capacity, excellent sliding performance, and superior corrosion resistance, making it ideal for marine equipment, heavy-duty shafts, bearings, valves, and industrial machinery.
