Aluminum Bronze Hollow Bar
C95400
Overview
C95400 is a heat-treatable aluminum bronze offering high strength, excellent wear resistance, and superior corrosion resistance — especially in marine and chemical environments. It provides approximately twice the strength of SAE 660 bearing bronze while maintaining good machinability. C954 is widely used for heavy-duty bearings, gears, valve components, and marine hardware where strength and corrosion resistance are critical.
