Cost comparison between aluminum alloy die-casting parts and zinc alloy die-casting parts

　　When it comes to processing aluminum alloy die-casting parts, it is necessary to first understand what aluminum alloy die-casting parts are, right? Aluminum alloy die casting is a type of pressure casting part that uses a pressure casting mechanical die casting machine with a casting mold installed. The heated aluminum or aluminum alloy is poured into the feeding port of the die casting machine, and then die cast to produce aluminum parts or aluminum alloy parts with the shape and size limited by the mold. Such parts are usually called aluminum alloy die castings. Aluminum alloy die-casting parts have different names in different places, such as aluminum die-casting parts, die-casting aluminum parts, aluminum alloy die-casting parts, etc. In recent years, with the rapid development of die-casting technology, aluminum alloy die-casting parts have been widely used in various industries of the national economy.

　　1. The density of zinc alloy material is relatively low compared to aluminum alloy material, so under the same product structure, the cost of making zinc alloy die-casting parts will be relatively high compared to aluminum alloy.

　　2. In the selection of die-casting mold materials, the working conditions of aluminum alloy die-casting molds are different from other molds, generally requiring operation at around 500 degrees Celsius. In addition to being subjected to high pressure, they also have to withstand high temperature effects. So for the steel used in aluminum alloy die-casting molds, it is necessary to choose excellent cutting processability, good thermal stability, good polishing performance, sufficient surface hardness and wear resistance. The price is several times higher than that of steel used in zinc alloy die-casting molds.

　　Based on the above two points, it can be concluded that the cost of aluminum alloy die-casting parts and zinc alloy die-casting parts is comparable. However, zinc alloy has better strength, hardness, and forming function than aluminum alloy. The die-casting technology of zinc alloy die-casting is also more mature compared to aluminum alloy die-casting technology, and some product structural characteristics and performance determine the choice of materials. Therefore, under the premise of considering the cost comprehensively, it is still necessary to ensure product quality.
