bedra 63000
Aluminum Bronze
Characteristics:
This alloy is a copper-aluminum-iron-nickel quaternary alloy, hardened by aluminum solid solution strengthening. It exhibits high strength and wear resistance. Additionally, due to the formation of a dense aluminum oxide protective layer on its surface, the alloy demonstrates excellent high-temperature corrosion and oxidation resistance, as well as corrosion resistance in atmospheric, freshwater, and seawater environments. It can be welded and performs well in hot pressure processing.
Typical applications:
It is commonly used in high-strength screws, nuts, copper sleeves, sealing rings, and related hardware components.
