Manganese Bronze Description

Manganese bronze is an important metal that is very strong and can resist corrosion. C86300, the standard bearer of this alloy, is a perfect blend of copper, zinc, manganese, aluminum, iron, and tin. This metal has great strength and can resist corrosion, which makes it useful for many different things.

Manganese bronze is very strong and and can handle slow speeds and heavy loads. This makes it good for tough jobs.

Outstanding Wear Characteristics: This alloy is very strong and can handle abrasion and friction well.

Manganese bronze is a non-heat treatable alloy, simplifying fabrication processes while maintaining exceptional mechanical integrity.

Manganese bronze is good for things that need to be strong and wear resistant. Examples are as follows:

  • Bearings and Bushings: Good for bearings that have to handle heavy loads and slow speeds. They make the bearing work well and last a long time.

  • Gears and Cams: Manganese bronze is a good choice for gears and cams in machines and equipment because it is strong and doesn't break easily.

  • Marine Components: Manganese bronze is good for marine parts because it doesn't get corroded in the water. It can be used for things like boat hardware and propeller shafts.

  • Valve Components: Manganese bronze is a good choice for valve components that need to be durable and reliable.

  • Agricultural Equipment: Manganese bronze parts for agricultural machinery can handle the toughness of farming and work well.

Manganese bronze is made by mixing copper with certain amounts of zinc, manganese and tin. The alloy is then cast or forged into the shapes and sizes you want, so it's uniform and safe across the product range.

Manganese bronze is generally safe to handle, but you should take care not to get too close to fumes or dust during machining and fabrication processes.

As a company that makes manganese bronze, we make sure our products are good and reliable. We make sure our manganese bronze alloys meet the highest standards in the industry, so our customers can have the performance and durability they want.
