In order to improve the strength characteristics of such bronze is subjected to aging at a temperature of 250−300°C for 2−3 hours after hardening at a temperature of 950 °C. It is used in the production of valve seats, bushings, worms, gears, nuts adjusting screws in mashinostroenii. The Nickel in the alloy composition contributes to the improvement of mechanical properties, heat resistance, corrosion resistance increases, the recrystallization temperature, improves anti-friction properties, stability at low temperatures. Bronze aluminum-iron-Nickel is used for the guide bushings, gears, valves and other critical parts to purpose in the aircraft industry. Manganese in the alloy composition contributes to corrosion, technological properties. Bronze aluminum-iron-manganese processed well in cold, hot conditions under pressure. They are used in manufacturing, worm screws, bushings, gears, which are operated at temperatures up to 250 °C in marine shipbuilding.
