There are many differences between aluminum alloy handles and zinc alloy handles. Xiaobian tells you slowly:
1. Alloy handles and aluminum alloy handles. The main difference is that the die-casting cost of zinc alloy handles is cheaper, and if the aluminum alloy is to be die-casted, then the die cost is not a small cost.
2. In terms of the price of light products. Aluminum alloy handles have advantages. Zinc alloy handles are more than half the weight of aluminum alloys with the same size handles. The late fee increase is. Electroplating is more expensive than oxidation. Of course, if it is Aluminum profiles are cheaper. Aluminum alloys have good plasticity but low strength, but their specific strength is higher. They are suitable for medium structural materials that carry large weights. Aluminum alloys and zinc alloys have better corrosion resistance. performance.
3. Zinc alloy has higher hardness and higher tensile strength than aluminum alloy, but there is no limit. The density of aluminum alloy is small, the hardness is also great, and the tensile strength is better. Pick it up, the zinc alloy is heavier.
4. The finish of aluminum alloy is better. Zinc alloys of the same weight are cheaper than aluminum alloys. In fact, due to the higher density of zinc alloys, the price of zinc alloys and aluminum alloys of the same volume is not much different. Compared with fine 304 stainless steel and copper, it is more cost-effective and more suitable for ordinary household use. Aluminum alloy is not easy to be oxidized, but its hardness is not as good as zinc alloy. Zinc alloy is easily oxidized and deteriorated in air for a long time, and it will become brittle and easy to break over time.
5.Aluminum alloy has low density but high strength. It is close to or larger than the quantity of excellent steel. It has good plasticity and can be processed into various profiles. It has excellent electrical conductivity, thermal conductivity and corrosion resistance. It is widely used in industry. The quantity is second only to steel. If the structure and die casting process allow, of course, it is more cost-effective to use aluminum alloy.
6. The specific gravity of zinc alloy is about 2.5 times that of aluminum alloy, and the price is equivalent. Therefore, zinc alloy is two or three times more expensive than aluminum alloy in terms of material cost. Many companies now want to replace zinc alloys with aluminum alloys in order to save costs, but some cannot be replaced because the strength, hardness and formability of zinc alloys are much better than aluminum alloys.
7. If the surface of your product is to be polished and electroplated and requires high appearance quality, then zinc alloy will be used. The material of the aluminum alloy handle is difficult to achieve high surface quality requirements, because aluminum alloy die-casting performance is poor, a lot of pores are easy to be produced on the surface of the product, and the surface quality after plating is very poor.
8. There are many specifications and uses for alloys. The price of copper is high, so that more than 70% of zinc alloy die-casting products are made of No. 3 zinc alloy, locks and other hardware components, or ordinary windows, electroplating and other industrial sectors. Aluminum alloys are generally used in chemical, tableware, electronic communications, electronics, aviation, machinery, spraying and chrome-plating surface treatments, motorcycles. No. 3 zinc alloy plating, anti-theft windows, products are widely used in automobiles, widely used in aerospace, electrical, and marine. No. 3 zinc alloy has good castability and dimensional stability. Mechanical parts such as meters, ornaments, and toy iron are easy to rust.
