Special feature of bronze CuAl9Mn2 is a significant optimization of mechanical properties. By grinding grain, iron provides a delay of recrystallization. In order to improve strength properties, aluminium-iron bronze is aged at a temperature of 250−300 ° C for 2−3 hours after completion of thermohardening at temperature of 950 ° C. It is used in a manufacture of valve seats, bushings, worms, gears, screw boxes in mechanical engineering. Nickel provides increasing of mechanical properties, heat resistance, corrosion resistance, recrystallization temperature. It also increases antifriction properties, resistance to low temperatures. Aluminium-iron bronzes are used for pin bushes, gears, valves, essential parts in aircraft industry, etc. Manganese provides increasing of corrosion and technological properties. Aluminium-iron bronzes can be perfectly pressure-treated in cold condition. They are used in a manufacture of worm screws, bushings, gears, which are operated at a temperature of up to 250 ° C in marine shipbuilding.
