C61000 Details & Applications:
C61000 Aluminum Bronze

CuAl8 – UNS.C61000 Aluminum Bronze Alloys, Nominally composed of 92% copper and 8% aluminum, which is known for its hardness, high strength, wear and corrosion resistance. Although it is an engineering alloy, its rich gold color also allows its use in decorative applications, and it has good hot and cold workability. So its applications including welding wire, bolts, tie rods, shafts, and pump parts.

Typical Application for C61000 Aluminum Bronze Alloys:

Architecture: Decorative Applications
