Ampco Metal AMPCO® 863 Manganese Bronze, Continuous Cast
Categories: Metal; Nonferrous Metal; Copper Alloy; Bronze

Material Notes: Ampco 863 has high strength and corrosion resistance. The consistent superiority of Ampco 863 alloy over commercial bronze is due, in large part, to the unique distribution of alloy microstructure, often referred to as the Ampco-Phase. Only Ampco alloys offer this metallurgical advantage.

Applications: Ampco 863 gives high strength and corrosion resistance which makes this alloy ideal for heavy duty construction markets. It will outperform and outlast ordinary bronzes and should be used also for bearings, worm gears, cams, connector rods, lead screw nuts, etc. Superior corrosion resistance and high strength lends this alloy to many construction and agricultural equipment applications. Segmented bushings and sleeve bearings are the main applications of Ampco 863.
