C69300 – BRONZE ROD
Your Lead-Free High-Performance Bronze
ECO BRONZE® C69300 is a versatile lead-free alloy that can be used in many wear applications including bushings, bearings, gears, worm gears, etc. ECO BRONZE® bearings have been independently tested through multiple independent laboratories and has proven to be as good or better than the traditional wear alloys. ECO BRONZE® continuous cast and centrifugal cast product offers excellent machinability, resistance to galling, and has good wear characteristics versus C932 and C954. It has high tensile strength equivalent to 303 annealed stainless and excellent compressive strength. Its static and dynamic coefficient of friction is similar to C93200 (SAE660). Best of all, it is lead-free and 100% recyclable as well as RoHS compliant.
Adding to ECO BRONZE® versatility, it is also ideal for use in water and potable water applications. It is often used in water carrying devices including valves bodies, valve stems, valve balls, water meter body, agriculture pipe, fire protection devices, shower valves, etc. because of its superior dezincification and stress corrosion resistance. It easily welds, solders, and brazes, and accepts plating.
