C67400 High Tensile Manganese Bronze Rods
C67400 High Tensile Manganese Bronze Rods is a high tensile brass which is alloyed with aluminum, manganese and silicon etc. which makes this alloy almost as hard as aluminum bronze, but considerably easier to process. CW713R also has good corrosion, wear resistance and machinability.
Typically this alloy is used in the automotive and hydraulic industries in forms of products such as Bearings for high load, slide-& wear-plates, valve guides, piston parts etc.
