AMPCO METAL AMPCO® 674 Manganese Bronze
Subcategory: Copper Alloy; Nonferrous Metal; Bronze
Key Words: UNS C-67400
Material Notes: Ampco 673 and 674 are wrought zinc-manganese-siliconlead-copper alloys. Both alloys have excellent capacity for hot forming, with hot forgeability ratings of 100. Ampco 674 exhibits a machinability rating of 25%, while Ampco 673 has a considerably higher rating of 80%. This significant difference in the two materials is in the higher lead content of Ampco 673 which increases that alloy`s machinability but decreases its tensile and yield values.Applications: Widely specified for a variety of bearing and/or corrosive applications: bushings; gears; cams; nuts and bolts; connector rods; idler shafts and other shafting; worm gears; feed fingers; lead nut screws, etc.
