Aluminum handles and zinc handles are one of the most common hardware accessories in our daily life. Their excellent performance and outstanding performance have won the choice of many home consumers. Next, we will briefly explain the differences between them. , I hope it will be helpful for everyone to master this knowledge.
1. Compare the aluminum alloy handle with the zinc alloy handle, each has its own merits. Depends on where it is used. The main difference is that the die-casting cost of the zinc alloy handle is cheap, but the die-casting of the aluminum alloy is quite expensive.
2. Regarding the price of aluminum products, aluminum alloy handles have an advantage. The same size handle is more than half the weight of the zinc alloy. And the additional cost in the later stage, electroplating is higher than oxidation. Of course, it will be cheaper to use aluminum profiles. Aluminum alloy has good plasticity, but low strength, but high specific strength.
3. Zinc alloy materials have higher strength and compressive strength than aluminum alloy profiles, but there is no absolute boundary. The relative density of aluminum alloy profiles is small, and the strength is also very large. For example, the aluminum alloys of the 2*** series and 7*** series have very high strength and good compressive strength. Pick it up, the zinc alloy material is heavier.
4. The finish of aluminum alloy is better. Zinc alloys are cheaper than aluminum alloys for the same weight. In fact, due to the higher density of zinc alloys, the price difference between zinc alloys and aluminum alloys for the same volume will not be much. Compared with high-quality 304 stainless steel and copper, it is more cost-effective and more suitable for ordinary household use. Aluminum alloy is not easy to oxidize, but its strength is not as good as that of zinc alloy material. Zinc alloy material is prone to air oxidation and mildew in the air for a long time. There is no problem with hardware locks under normal circumstances, no matter what material, as long as the lock itself is normal, there is no big difference in which material.
5. Aluminum alloy has low density, but high strength, close to or surpassing high-quality steel, good plasticity, can be processed into various profiles, with excellent electrical conductivity, thermal conductivity and corrosion resistance, widely used in industry, and its dosage is second only to steel . Of course it is more cost-effective to use aluminium alloys if construction and die casting technology allow.
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 2 or 3 times higher than that of aluminum alloy. Now, in order to save costs, many companies want to use aluminum alloys instead of zinc alloys, but because of the strength, hardness and formability of zinc alloys, there are also products that cannot be replaced.
7. If the surface of your product needs to be polished and coated, and high appearance quality is required, you must use zinc alloy. The material of the aluminum alloy handle is difficult to meet the high surface quality requirements, the die-casting formability of the aluminum alloy is poor, the product surface has many pores, and the surface quality after electroplating is poor.
