Zinc Alloy Door Handle vs. Aluminum Alloy Handle

As we all know, zinc alloy and aluminum alloy are both common metal for producing furniture pulls and knobs. The two kinds of metals have their advantages and disadvantages respectively. What are the differences between them? Reading the following paragraphs you will find the answers. We hope this passage will help you select pull handles.

 

1. Price

As far as the product price is concerned, aluminum alloy handles have advantages. For example, for cupboard handles of the same size, those made from zinc alloy are much heavier than those made from aluminum alloy. In addition, the cost of later processing of aluminum handles is lower. Aluminum alloys have good plasticity, low strength. And both aluminum alloy and zinc alloy are resistant to corrosion.

 

 

2. Hardness

Zinc alloy is harder and has higher tensile strength than aluminum alloy. Aluminum alloy has lower density and lower hardness. So comparing two metal handles made from the two materials, you will find the zinc alloy is heavier.

 

 

3. Degree of finish

The finish of aluminum alloy is better. Compared with high-quality 304 stainless steel and copper, zinc alloy is more cost-effective and more suitable for ordinary household use. Aluminum pulls and knobs are not easy to be oxidized, but its hardness is not as high as zinc alloy. On the contrary, zinc cabinet pulls are easy to be oxidized and deteriorated in the air after a period of time, and it will become very brittle after a long time. Under normal circumstances, there is no problem with the metal locks. No matter what the material is, as long as the lock itself is okay, there is no big difference.

 

 

4. Density

Aluminum alloy has low density but relatively high strength, which is close to or exceeds that of high-quality 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.

 

 

5. Gravity

The specific gravity of zinc alloy is about 2.5 times of the specific gravity of aluminum alloy, but the unit price is equivalent, so the cost of zinc alloy handles is two or three times than aluminum alloy handles. Many companies now want to replace zinc alloy with aluminum alloy in order to save costs, but in some aspects, zinc alloy cannot be replaced because the strength, hardness and formability of zinc alloy are much better than aluminum alloy.  

 

 

6. Processing

If the surface of your wardrobe handles need to be polished and electroplated, and high appearance quality is required, zinc alloy must be used in your handles. It is difficult for the aluminum alloy handle to meet high requirements for appearance quality, because aluminum alloy performs poor in die-casting molding, so there will be many pores on the surface of the product, and the quality of the surface after electroplating is also very poor.

 

After the introduction, you must have the answer in your mind and can choose handles for your doors and even your other furniture. We sell aluminium window handles, aluminum drawer pulls and so on. You are allowed to choose from various styles.
