Manganese Bronze Sand Castings
Leitelt Brothers designs and manufactures manganese bronze sand castings known for their high quality and superior workmanship. We offer a full range of Value-Added Services and Additional Capabilities that can be added to any project.
Manganese bronze and white manganese bronze alloys are comprised of:
- 55 to 65% Copper (Cu)
- 20 to 25% Zinc (Zn)
- 1 to 5% Manganese (Mn)
- 1 to 5% Iron (Fe)
These alloys have good corrosion resistance, high strength, high wear, and good mechanical properties.
Leitelt Brothers manufactures three common grades of manganese bronze alloys:
- CA86300 (424) (ASTM B5854-863) High Strength - 110, 000 Tensile
- CA86500 (421) (ASTM B5854-865) High Strength - 65,000 Tensile
- CA99700 (Tombasil) White Manganese Bronze
CA86300 Typically used for screw down nuts, slow-speed, heavy load bearings, gears, and cams.
CA86500 Typically used for propellers, machinery parts substituting for steel or malleable iron
CA99700 Typically used for ornamental castings, marine hardware, and excellent corrosion resistance.
