Bronze
DESCRIPTION
Manganese bronze contains small additions of manganese, iron, and aluminium, plus lead for lubricity, anti-seizing, and bonding. Like the aluminium bronzes, they combine high strength with excellent corrosion resistance. Manganese bronze bearings can operate at high speeds under heavy loads, but require high shaft hardness and nonabrasive operating conditions. The various types of manganese bronze are a popular choice for the aerospace, fastener, marine, and oil and gas Industries. Typical applications in these industries include landing gear parts, strut bushings, screw machine parts, bearings, bushings, gears, and lead screw nuts.
