AMPCO® 18.23 High‑Strength Centrifugal Castings – Superior Wear Resistance & Bearing Performance
This heat-treated alloy is the ultimate in high-strength bronzes requiring good bearing characteristics and exceptional wear resistance. It has greater toughness than grade AMPCO® 18.22 and better physical properties than grades AMPCO® 18 or AMPCO® 18.136. Its exceptional proportional limit gives it a maximum resistance to distortion, enabling the designer to take full advantage of its high physical properties.
