The difference between nickel bronze and tin bronze is that aluminum bronze can be strengthened by heat treatment, its strength is higher than that of tin bronze, and its high temperature oxidation resistance is better. Nickel-aluminum bronze is relatively poor and has different elements. Tin bronze: bronze with tin as the main alloying element. Aluminum bronze: It is a copper-based alloy with aluminum as the main alloying element. There are also different tin contents.
