1.Tin bronze :
Ingredients: Mainly contains tin, and small amounts of other elements such as copper, zinc, lead, etc.
Performance characteristics: good wear resistance, corrosion resistance and high strength. Tin bronze has a large solidification range and severe dendrite segregation, but it is not easy to form concentrated shrinkage holes during solidification, and the volume shrinkage is very small; in the liquid alloy, tin is easy to form hard and brittle inclusions SnO₂, and it must be fully deoxidized during smelting to prevent the mechanical properties of the alloy from being reduced due to inclusions; it is very sensitive to overheating and gas, and can be well welded and brazed; no sparks occur during impact, it is non-magnetic, cold-resistant, and has extremely high wear resistance.
2. Aluminum bronze:
Composition: Aluminum is the main alloy element, and it also contains a certain amount of copper and a small amount of other elements such as iron, manganese, nickel, etc.
Performance characteristics: Aluminum bronze has high strength, hardness and good corrosion resistance. It has good corrosion resistance in the atmosphere, fresh water, sea water and certain acids. It can be welded by electric welding and gas welding, but is not easy to braze. It can withstand pressure processing in cold or hot states, but cannot be quenched and tempered to strengthen.
3. Lead Bronze:
Ingredients: The main ingredients are copper and lead, and it also contains small amounts of tin, zinc and other elements.
Performance characteristics: The load-bearing capacity of lead bronze is higher than that of bearing alloys, and it has better wear resistance and self-lubricating properties, but its adaptability is poor, so it is used in situations where the shaft has good rigidity and good concentricity.
In addition, in some special occasions, other types of bronze alloys may be used or special elements or compounds may be added to bronze to improve its performance to meet different working conditions and use requirements .
