C67300

Dynalloy Bronze Alloy

Previously known as Dynalloy, this alloy is corrosion-resistant and has high strength. It is known to be an excellent bearing against hardened surfaces. Dynalloy is typically used where greater ductility is required. This alloy is used against soft or hard mating members and it can be soldered. MUELLER Alloy 6730 is a medium-leaded copper-base alloy with good machinability. It can be used with hard or soft mating members where moderate strength is sufficient.
