The door handle is divided into aluminum alloy handles, zinc alloy handles, stainless steel handles, etc. Today we will talk about the difference between aluminum alloy handle and zinc alloy handle, which is easier for you to know which one to choose.
If you compare zinc alloy handle and aluminum alloy handle, they have their own advantages, depending on what you are using. The main difference is that the die-casting cost of the zinc alloy handle is cheaper. And if the aluminum alloy is die-casting, the cost of light mold is not small.
In terms of the price of light products, aluminum alloy handles have advantages. For the same size handle, the weight of zinc alloy is more than half of that of aluminum alloy. The later charge of electroplating is more expensive than that of oxidation. Of course, it's cheaper to use aluminum profiles. Aluminum alloys have good plasticity and are suitable for dresser knobs and kitchen cupboard handles. In addition, aluminum alloys and zinc alloys have good corrosion resistance.
Zinc alloy has higher hardness and higher tensile strength than aluminum alloy, but there is no absolute limit. Aluminum alloys have low density, high hardness and good tensile strength. However, zinc alloys are heavier and suitable for cabinet pull and sliding door handles.
The finish of aluminum alloy is better. Zinc alloy of the same weight is cheaper than the aluminum alloy. In fact, due to the high density of zinc alloy, the price difference between zinc alloy and aluminum alloy with the same volume is not too much. Aluminum alloy is not easy to oxidize, but its hardness is not as good as a zinc alloy. Zinc is easy to oxidize and deteriorate in the air for a long time, which will become brittle and easy to break. In general, there is no problem with locks, no matter what the material. As long as there is no quality problem with the lock itself, there is no big difference in the material used. You can choose ceramic door knobs or silver door handles according to your preference.
Aluminum alloys have low density but high strength, which is close to or better than high quality steel. In addition, it has good plasticity and can be processed into various profiles. Due to its excellent electrical conductivity, thermal conductivity and corrosion resistance, it is widely used in industry, and its usage is only inferior to steel. If the structure and die casting process permit, it is more cost-effective to use aluminum alloys. Therefore, you can select cupboard door handles and cabinet door handles as needed.
The proportion of zinc alloy is about 2.5 times that of aluminum alloy, and the price is the same. Therefore, the material cost of zinc alloy is two or three times higher than that of aluminum alloy. Now many enterprises want to replace zinc alloys with aluminum alloys in order to save costs, but some cannot be replaced because the strength, hardness and molding performance of zinc alloys are much better than aluminum alloys.
If you want to polish the surface of the product electroplating, and require a high appearance quality, it has to use a zinc alloy. Aluminum alloy handle material is difficult to meet the requirements of high surface quality. Because of the poor performance of aluminum alloy die casting, the surface of the product is easy to have a lot of pores, and the surface quality is poor after electroplating.
Now you know the difference between the two alloys! Choose the door knobs you want!
