Aluminum alloy and stainless steel are common materials in our life. They have their own characteristics and are suitable for different occasions. This paper will reveal the difference between aluminum alloy and stainless steel from six aspects: origin, price, hardness, appearance, anti-aging and beware of traps, so as to help readers choose materials better.

Birth difference

Aluminum alloy is mainly aluminum, supplemented by a small amount of metals such as manganese; While stainless steel is mainly iron. The composition of the two is different, so the performance is different.

price war

The price of aluminum alloy doors is close to the people, while stainless steel is a luxury lineup. According to the demand and budget, choose the materials that suit you.

Hardness primary key

Stainless steel is as hard as diamond, and aluminum alloy is a little bit harder. According to the use and demand, choose materials with moderate hardness.

Appearance Association

There are many surface treatments of aluminum alloys, such as electrophoresis, spraying and anodizing. On the other hand, stainless steel keeps its original color. According to personal preferences and use occasions, choose the material that suits you.

The secret of anti-aging

Stainless steel has strong corrosion resistance, while aluminum alloy is weak. If it needs to be used for a long time, it is recommended to choose stainless steel with stronger corrosion resistance.

Beware of traps

In the stainless steel market, bad manufacturers emerge one after another, and the phenomenon of cutting corners such as material thickness and composition occurs from time to time. When selecting materials, we must pay attention to quality to avoid being cheated.
