What are the differences between aluminum alloy handles and zinc alloy handles?

Jun 21, 2022

There are many differences between the aluminum alloy handle and the zinc alloy handle. The editor will tell you slowly:

1. Alloy handle and aluminum alloy handle. The main difference is that the die-casting fee of zinc alloy handle is cheaper, and if the aluminum alloy is to be die-casted, the cost of the mold is a lot of money.

2. As far as the price of the light product is concerned, the aluminum alloy handle has advantages. The handle of the same size, the zinc alloy is more than half heavier than the aluminum alloy. And the later fee is added. Electroplating is more expensive than oxidation. Of course, if it is It is cheaper to use aluminum profiles. Aluminum alloys have good plasticity, but low strength, but their specific strengths are higher. They are suitable for medium structural materials that carry large weights. Both aluminum alloys and zinc alloys have good corrosion resistance. performance.

3. Zinc alloy has higher hardness and higher tensile strength than aluminum alloy, but there is no limit. Aluminum alloy has low density, high hardness, and good tensile strength. Pick it up, the zinc alloy is heavier.

4. The finish of aluminum alloy is better. Zinc alloy of the same weight is cheaper than aluminum alloy. In fact, due to the high density of zinc alloy, the price of zinc alloy and aluminum alloy of the same volume is not much different. Compared with excellent 304 stainless steel and copper, it is more cost-effective and more suitable for ordinary households. Aluminum alloy is not easy to be oxidized, but its hardness is not as good as that of zinc alloy.

5. The density of aluminum alloy is low, but the strength is relatively high, close to or greater than the number of good steel, good plasticity, can be processed into various profiles, with excellent electrical conductivity, thermal conductivity and corrosion resistance, widely used in industry, using 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 proportion of zinc alloy is about 2.5 times that of aluminum alloy, and the price is equivalent, so the material cost of zinc alloy is two or three times more expensive than that of aluminum alloy. Nowadays, many companies want to use aluminum alloys to replace zinc 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 needs to be polished and electroplated, and high appearance quality is required, then zinc alloy will be used. It is difficult for the aluminum alloy handle material to meet the high surface quality requirements, because the aluminum alloy die-casting performance is poor, and there are many pores on the surface of the product, and the surface quality is very poor after electroplating.

8. There are many specifications and uses of 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, hardware such as locks, or ordinary windows, electroplating and other industrial sectors. Aluminum alloys are generally used in chemical, tableware, electronic communications, electronics, aviation, machinery, spraying and chroming and other surface treatments, motorcycles. No. 3 zinc alloy electroplating, anti-theft windows, the products are widely used in automobiles, widely used in aerospace, electricians, ships. No. 3 zinc alloy has stable castability and size, and mechanical parts such as instruments, accessories, and toy iron are easy to rust.
