Manganese Bronze

Manganese bronze alloys encompass minor alloying elements such as manganese, iron, and aluminum, in addition to lead for enhancing lubricity, preventing seizing, and promoting bonding. Similar to aluminum bronze alloys, they offer a combination of impressive strength and exceptional resistance to corrosion. Manganese bronze bearings are well-suited for high-speed operations under substantial loads, yet necessitate stringent requirements for shaft hardness and the absence of abrasive environmental conditions. These various forms of manganese bronze alloys are widely favored within the aerospace, fastener, marine, and oil and gas sectors. Common applications in these industries encompass components like landing gear parts, strut bushings, screw machine parts, various types of bearings, bushings, gears, and lead screw nuts.
