ASTM B249, QQ-C-465, AMS 4631, AMS 4634, EU
Designation: CuAl7Si2, CW302G The C64200 silicone aluminum alloy is an engineering alloy which is resistant to corrosion as copper and is much stronger. Is is manufactured in round, hexagonal and octagonal rods for hot forming and free machining. It is considered as best valve stem alloy and its other applications include gears, marine hardware, nuts, pole line hardware, and valve bodies and components.

Typical Applications:

  • Automotive : Valve Guides, Automobile Engine
  • Electrical: Pole Line Hardware
  • Fasteners: Bolts, Nuts
  • Industrial: Valve Components, Valve Bodies, Gears, Valve Stems, Cams
  • Industrial: Marine: Hardware
