Features of aluminum bronzes
Feature of aluminum bronzes is that iron significantly increases their mechanical characteristics, grain crushing, which provides a delay recrystallization. To improve the strength properties of the aluminum-iron bronze subjected to aging at a temperature of 250−300°C two to three hours after quenching at t° 950 °C. It is used in the production of worms, gears, bushings, nuts, adjusting screws, valve seats, usually in the aviation industry.
Nickel contributes to increasing the mechanical characteristics, heat resistance, improves corrosion resistance and recrystallization temperature of aluminum bronzes, stability at low temperatures and low friction characteristics. Aluminum-iron-Nickel bronze used for valve guides, bushings, gears and other parts for critical applications, typically in the aircraft industry.
Manganese contributes to the enhancement of technological and corrosion properties of bronze. Aluminum-iron-Nickel bronze are perfectly processed under pressure in cold and hot condition. They are used for the production of gears, worm screws, bushings, and in marine shipbuilding for parts operating at temperatures up to 250 °C.
