The Difference Between Led Aluminum Profile Shell and Stainless Steel Shell

The difference between led aluminum profile shell and stainless steel shell
1. Differences in composition
The main elements of the aluminum profile housing shell are aluminum, silicon, copper, magnesium and zinc. According to the content of each element, the performance of the aluminum shell body will also be different. The stainless steel housing is cast from steel. Chromium, nickel, manganese, silicon, copper and other metals are added in the smelting process. Chromium is the main alloying element. Generally, the content of chromium in stainless steel is at least 10.5%. The aluminum profile shell and the stainless steel shell are different in composition, so many people in life think that stainless steel is an aluminum profile shell is actually wrong.
Second, the difference in corrosion resistance
The corrosion resistance of the aluminum profile housing is due to the formation of a corrosion-resistant oxide film on the surface, which can prevent further corrosion of the internal metal. Stainless steel mainly contains corrosion-resistant nickel-chromium alloy, so when the application field of the product requires corrosion resistance, the stainless steel housing is the first choice.
3. Price difference
The price of aluminum profile shells and stainless steel shells depends not only on the cost of raw materials, but also because of their difficulty in processing. The hardness of aluminum profile shells is lower than that of stainless steel, and it is easy to cut and form, so the price of aluminum profile shells is generally lower than that of stainless steel shells, of course, this is not general, because in practical applications, the number of processing techniques the shell has undergone and Type is also a factor in determining price increases.
Fourth, the difference in weight and hardness
The density of aluminum profiles varies with the addition of alloying elements, generally 2.5 × 10 kg/m-2.8 × 10 kg/m? Therefore, the weight of the aluminum profile shell is lighter than that of the stainless steel shell, which is almost 1/3 of the weight of the stainless steel shell. , which makes the aluminum profile shell very suitable for the manufacture of mobile phone, camera, computer and other electronic product shells, with the effect of being light and portable. The hardness of stainless steel is higher than that of aluminum profile shell, and the stainless steel shell has strong scratch resistance and impact resistance, which can be used in medical equipment and chemical testing equipment.
5. Differences in thermal conductivity and heat dissipation capacity
The thermal conductivity of the aluminum profile shell is very different from that of the stainless steel. The specific heat capacity is 460 J/(kg.K), so it is not difficult to find that the aluminum profile shell has good thermal conductivity. The reason for the profile housing shell.
