Manganese optimizes technological properties. Nickel provides increasing of strength, heat resistance, corrosion resistance, recrystallization temperature. It also increases antifriction properties, resistance to low temperatures. In order to improve strength characteristics, aluminium-iron bronze is exposed to age-hardening at a temperature of 250−300°С for 2−3 hours on completing thermohardening (t° 950 °C).
