- Excellent capacity for hot forming.
- Hot forgeability ratings of 100.
- Machinability rating of 80%.
AMPCO® 673 and AMPCO® 674 share many base characteristics as two wrought zinc-manganese-silicon-lead-copper alloys, specially developed for unique conditions. AMPCO® 673’s higher lead content increases its machinability but decreases its tensile and yield values.
Bushings, gears, cams, nuts and bolts, connector rods, idler shafts and other shafting, worm gears, feed fingers, lead nut screws.
Ideally suited for
