aluminium sliding door profiles.What kind of materials should be used for high-quality aluminum alloy die castings

　　Aluminum alloy die-casting parts, as one of the most commonly used die-casting parts, have been applied in many fields. This is because aluminum alloy die-casting parts have advantages such as light weight, high strength, and corrosion resistance, and their prices are relatively cheap. Therefore, aluminum alloy die-casting parts may occupy the dominant position in the die-casting industry for a long time in the future, but can high-end aluminum alloy die-casting parts be made?

　　The saying goes that only by selecting and using good materials can we make good taste. To make good aluminum alloy die castings, we need to choose high-quality die cast aluminum alloys. Die cast aluminum alloys usually contain elements such as silicon, copper, magnesium, iron, zinc, manganese, nickel, titanium, etc. The content of these elements will directly affect the performance of aluminum alloy die castings. For example, silicon can improve the casting performance of die cast aluminum alloys, but excessive amounts can cause hard spots in aluminum alloy die castings, making them difficult to cut; For example, zinc can improve the flowability of die cast aluminum alloys, but excessive amounts can increase the thermal brittleness of aluminum alloy die castings and reduce their corrosion resistance; There is also iron element, which is a harmful substance in all aluminum alloys and can reduce the mechanical properties and flowability of die cast aluminum alloys, leading to mold sticking in aluminum alloy die castings.
