Bronze Hollowbar 863 offers high strength and high corrosion resistance. Unlike oil-impregnated SAE 863, this alloy doesn't have any oil and must be well-lubricated to operate smoothly. It is also not heat treatable. 863 is typically used for gears, valves, fasteners, load bearings, and hydraulics.
