Hardware handles and zinc alloy handles are two different types of handles. When we choose handles, we do not know how to choose them. What are the differences between hardware handles and zinc alloy handles?
1. Hardware handle and aluminum alloy handle The main difference is that the die-casting cost of the hardware handle is cheaper, and if the aluminum alloy is to be die-casting, the cost of the light mold is not small.
2. In terms of the price of light products, aluminum alloy handles also have advantages. For handles of the same size, zinc alloy handles are more than half as heavy as aluminum alloy handles. And the later fees are. Electroplating is more expensive than oxidation. Of course, if aluminum profiles are used, it is cheaper Aluminum alloy has good plasticity but low strength, but its specific strength is higher. It is suitable for medium structural materials with large weight. Aluminum alloy and zinc alloy have good corrosion resistance.
3. Zinc alloy has higher hardness and higher tensile strength than aluminum alloy, but there is no absolute limit. Aluminum alloy has low density, high hardness and good tensile strength. Take 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 difference between zinc alloy and aluminum alloy of the same volume is not much. Compared with high-quality 304 stainless steel and copper, it is more cost-effective and more suitable for ordinary families. Aluminum alloy is not easy to be oxidized, but its hardness is lower than that of zinc alloy. Zinc alloy is easy to be oxidized and deteriorated in the air for a long time, and will become brittle and easy to break.
5. Aluminum alloy has low density, high strength, close to or higher than high-quality steel, good plasticity, and can be processed into various profiles. It has excellent conductivity, thermal conductivity and corrosion resistance. It is widely used in industry, and its use is only second to that of 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 the same, so the material cost of zinc alloy is two or three times higher than that of aluminum alloy. In order to save costs, many enterprises now want to replace zinc alloy with aluminum alloy, but some cannot be replaced because the strength, hardness and molding performance of zinc alloy are much better than that of aluminum alloy.
