Blog Manganese Bronze Material Profile

By: Dave Olsen

Bronze castings


  • HIGH TENSILE (C86300) Manganese Bronze


  • Family of bronzes primarily known for its extremely high strength and ability to resist the corrosive effects of seawater and brine. Often referred to as Yellow Brass.

Properties – Why select this material

  • Tensile strengths range from 60,000 psi to 110,000 psi and are readily obtainable depending on the composition of the alloy chosen.
  • Great care must be taken when using these alloys as bearings because manganese bronze and steel do not wear well together. Wear is rapid, and under high loads and speed, a seizure can occur. Alignment must be precise and positive lubrication is essential.

Applications – Frequent uses

  • Trunnion bearings
  • Heavily stressed gears, worm gears, and worms
  • Gearshift forks
  • Impellers
  • Highly stressed machine parts.
