CDA642 (C64200)	Silicon aluminium bronze			CDA642 standards and properties

CDA642 (C64200) Silicon aluminium bronze is an engineering alloy at least as resistant to corrosion as copper itself, but much stronger.
CDA642 (C64200) is manufactured mostly in the form of round rods and bars for hot forming and free machining.
CDA642 (C64200) is considered to be of the best valve stem alloys. Other applications include gears, marine hardware, nuts, pole line
hardware, and valve bodies and components.
