Although aluminum alloy housing and stainless steel housing look similar, they are used in different fields. Even in the same field, the products are quite different. Do you know the difference between aluminum alloy enclosure and stainless steel enclosure?

Aluminum alloy and stainless steel materials are widely used in various industries. Stainless steel and aluminum alloy shells are becoming more and more popular in modern electronic products. With the continuous development and improvement of processing technology, stainless steel and aluminum alloy enclosure will be used more and more in various fields. The following is a brief introduction to the specific differences between the two:

1. Structural differences.

The density of aluminum profile is very small, only 2.7g/cm. Although it is relatively soft, it can be made into various aluminum profile alloys by synthesizing other metal elements, such as hard aluminum alloy, super hard aluminum alloy, antirust aluminum alloy, cast aluminum alloy, etc. Aluminum alloy is a good conductor of heat, and its thermal conductivity is three times that of iron. In industry, aluminum profiles can be used to manufacture various heat exchangers, heat dissipation materials and cookers. Aluminum alloy has very good ductility (second only to gold and silver). Aluminum alloy foil with thickness less than 0.01mm can be made at 100 ℃ ~150 ℃.

Stainless steel is made of steel. In the smelting process, chromium, nickel, manganese, silicon, copper and other metals are added. Chromium is the main alloying element. Generally, the chromium content in stainless steel shall be at least 10.5%. The density of aluminum alloy varies according to the added alloy elements, generally within 2.5 × ten ³  kg/m ³— two point eight × ten ³  kg/m ³ Therefore, the weight of aluminum alloy shell is much lighter than that of stainless steel shell, almost one third of which is the weight of stainless steel shell.

1. The corrosion resistance is different.

The corrosion resistance of aluminum alloy is due to the addition of corrosion-resistant oxide film on the surface, which can prevent further corrosion of internal metal.

Stainless steel is mainly nickel chromium alloy, which is corrosion resistant. If corrosion resistance is required for the products produced, stainless steel is recommended. Secondly, the stainless steel surface can be processed, and its appearance is more lovely and smooth than that of aluminum alloy. But the cost of stainless steel is higher than that of aluminum alloy.

1. price difference.

The price of aluminum alloy shell and stainless steel enclosure depends not only on the cost of raw materials, but also on their own processing difficulties. Compared with stainless steel, aluminum alloy has lower hardness and is easy to cut and shape. Therefore, generally speaking, the customized price of aluminum alloy enclosure is lower than that of stainless steel enclosure. Of course, this is not certain, because in practical application, the quantity and type of housing construction are also factors that determine the price trend.
