Description:
C61900 Copper-based alloys with aluminium as the main alloying element are aluminium bronzes with iron and manganese elements, which are high-strength heat-resistant bronzes.Aluminium content is generally not more than 11.5%, and sometimes add appropriate amounts of iron, nickel, manganese and other elements to further improve performance. Aluminium bronze can be strengthened by heat treatment, its strength is higher than tin bronze, resistance to high temperature oxidation is also better.
Higher strength, good wear resistance for high strength screws, nuts, copper bushings, sealing rings, etc., and wear-resistant parts, the most prominent feature is its good wear resistance.
Aluminium bronze containing iron and manganese elements has high strength and wear resistance, quenched and tempered to improve hardness, good high temperature corrosion resistance and oxidation resistance in the atmosphere, freshwater and seawater corrosion resistance is very good, machinability is still available, can be welded is not easy to braze, the hot state of the pressure processing is good.
Applications:
C61900 Aluminum bronze has good corrosion resistance, so it can be used to manufacture corrosion-resistant parts, such as propellers, valves, etc.
