Nickel Aluminum C63000 (CDA 630)

C63000 Nickel Aluminum Bronze is an excellent choice for applications that involve heavy loads, friction and abrasive wear. Adding nickel to the alloy's composition makes the resulting metal stronger without sacrificing its ductility or resistance to corrosion.

Also known as: CDA 630, ASTM B-150 Alloy C63000, SAE J461, J463, QQC-465B Alloy C63000
