　　Specific differences between zinc alloy die-casting parts and aluminum alloy die-casting parts

　　With the rapid development of die-casting metal processing technology, more and more fields are using die-casting parts. Due to the superior performance and process performance of zinc alloy die-casting parts and aluminum alloy die-casting parts in die-casting production, the development of zinc alloy die-casting parts and aluminum alloy die-casting parts is rapid, and their usage is much higher than other non-ferrous alloys, occupying an extremely important position in die-casting production. Customers often inquire about the differences between zinc alloy and aluminum alloy die-casting parts? Today we will discuss with you the differences between zinc alloy and aluminum alloy die-casting parts.

　　1. The difference in conceptual definition: Zinc alloy is an alloy composed of zinc as the base and other elements added. Common alloying elements include low-temperature zinc alloys such as aluminum, copper, magnesium, cadmium, lead, and titanium. Aluminum alloy is a general term for alloys based on aluminum, mainly containing alloying elements such as copper, silicon, magnesium, zinc, manganese, and secondary alloying elements such as nickel, iron, titanium, chromium, lithium, etc.

　　2. Performance differences: Zinc alloy has a low melting point, good flowability, easy fusion welding, brazing, and plastic processing, corrosion resistance in the atmosphere, and is easy to reuse and remelt as a blind material; But the brittle strength is low, and it is easy to undergo size changes due to natural aging again. The hardness of zinc alloy is 65 to 140, and the tensile strength is 260 to 440. Aluminum alloy has low density but high strength, similar to or exceeding high-quality steel, good plasticity, and can be processed into various profiles. It has excellent conductivity, thermal conductivity, and corrosion resistance. The hardness of aluminum alloy is 45 to 90, and the tensile strength is 120 to 290.

　　3. The difference in die-casting process: The melt temperature of zinc alloy die-casting parts is over 380 degrees, while the melt temperature of aluminum alloy die-casting parts is over 600 degrees. The die-casting equipment for zinc alloy and aluminum alloy is different.
