The application of new aluminum alloys in die casting is mainly reflected in its excellent mechanical properties, heat treatment effects, casting properties, welding characteristics and corrosion resistance. New aluminum alloys such as AlSi10MnMg, AlSi7MnMg, AlSi9MnMoZr, etc. have achieved sustainable development by incorporating high recycling rates and minimizing carbon footprint designs. These alloys have detailed carbon footprint calculations and explored the results of phase simulations, considering the sources of primary and recycled aluminum.

Characteristics of new aluminum alloys

The new aluminum alloys have the following characteristics:

· Mechanical properties: high strength and good static and dynamic mechanical properties.

· Heat treatment effects: some alloys can achieve optimal performance without heat treatment, reducing resource consumption and carbon footprint in the manufacturing process.

· Casting performance: The new aluminum alloy has excellent casting performance and is suitable for various complex die-casting structures.

· Welding properties: good welding properties, suitable for die castings that require welding.

· Corrosion resistance: excellent corrosion resistance, suitable for applications in various harsh environments.

These new aluminum alloys have the potential to redefine high pressure die casting (HP-DC) structures by enabling larger, thinner and higher integrity castings.
