What is the difference between aluminum alloy die casting and zinc alloy die casting? ? ?
From the die-casting process alone, the editor of Dongguan Jie Aosi Die-casting Factory has five years of die-casting experience and feels that the difference between aluminum alloy die-casting and aluminum alloy die-casting is as follows:
1. The processing technology and parameters are different. Aluminum alloys can make huge products, zinc alloys can't.
2. The melting temperature of the two alloys is different. The zinc alloy is more than 400 degrees, and the aluminum alloy must be more than 700 degrees.
3. Different processing equipment, although they are called die-casting machines, they are not universal at all. The tensile strength and thermal conductivity of aluminum alloy are better than those of zinc alloy, and the surface treatment effect of zinc alloy is better than that of aluminum alloy.
The difference between aluminum alloy die casting and zinc alloy die casting performance
Zinc alloy has a low melting point, good fluidity, easy fusion welding, brazing and plastic processing, corrosion resistance in the atmosphere, and easy reuse and remelting of blind materials; but low brittle strength, easy to occur again due to natural aging. The hardness is 65 to 140 and the tensile strength is 260 to 440. Aluminum alloy has low density, but relatively high strength, similar to or as high as high-quality steel, good plasticity, can be processed into various profiles, with excellent electrical conductivity, thermal conductivity and corrosion resistance, aluminum alloy hardness is 45 to 90, tensile strength Intensity is 120 to 290.
There are some essential differences between zinc die castings and aluminum alloy die castings, which can be seen from the definition of zinc alloys. Zinc alloys are based on zinc and are combined with other metal elements. Metal zinc is optimized and has some diversified properties that metal zinc does not have, and makes up for some zinc defects. Therefore, zinc alloy die castings are more widely used than zinc die castings, and can better meet the needs of various use environments for die castings. requirements. I believe that Dongguan Jie Aosi Die Casting Factory, because Jie Aosi Precision Die Casting has been engaged in die-casting customization for 11 years, is a die-casting manufacturer specializing in precision die-casting zinc alloy, aluminum alloy die-casting and machined products. Its strength should not be underestimated, and it can independently complete a complete set of die-casting. Parts processing custom process,
