What are the main varieties and characteristics of aluminum alloy?

The main varieties of aluminum alloy are aluminum-copper alloy, aluminum-zinc alloy, aluminum-silicon alloy, aluminum-magnesium alloy, aluminum-manganese alloy, aluminum-lithium alloy and aluminum-titanium alloy.

• Aluminum-copper alloy: high strength and corrosion resistance, good thermal conductivity and electrical conductivity.

• Aluminum-zinc alloy: good mechanical properties and corrosion resistance, but also has good plasticity and welding performance.

• Aluminum-silicon alloy: excellent high temperature resistance and wear resistance, good rheological properties and low expansion coefficient.

• Aluminum-magnesium alloy: good strength and corrosion resistance, good seismic performance and plasticity.

• Aluminum-manganese alloy: good toughness and plasticity, good wear resistance and corrosion resistance.

• Al-Li alloy: high strength, lightweight, excellent strength and rigidity, good corrosion resistance and weldability.
