Difference between Stainless steel 201 and 304Two types of stainless steel 201 and 304, which differ in composition, performance and application areas.1. Chemical composition201 stainless steel contains 15% chromium and 5% nickel, while 304 stainless steel contains 18% chromium and 9% nickel.

8000 series&9000 series

Representing： 7075 It mainly contains zinc and belongs to the aviation series, which is not only aluminum magnesium zinc copper alloy but also heat treatable alloy. It belongs to superhard aluminum alloy and has good resistance.

Aluminum Coil Series-6000 SeriesStands series： 6061 It contains two elements of magnesium and silicon, which concentrated the advantages of 4000 series and 5000 series. 6061 aluminum is a cold-treated aluminum forging product, suitable for applications with high corrosion resistance and oxidation req

The main characteristics of aluminum：①Aluminum is a silver light metal with a density of about 2.72 g/cm3, which is about 1/3 of pure copper.②The calorific capacity of aluminum and its Latent heat of melting is high. The melting point of pure aluminum is about 661 ℃,

Stands series： 5052.5005.5083.5A05. 5000 series aluminum plate belongs to the more commonly used alloy aluminum plate series.

The 4000 series aluminum plate belongs to the series with higher silicon content, which usually between 4.5-6.0%.Represented by: 4A01Application: construction materials, mechanical parts, forging materials, welding materials.Features: Low melting point, good corrosion resistance

This series is mainly represented by the 3003 3003 3A21.3000 series aluminum plate can also be called anti-rust aluminum plate.

The feature of 2A16 (LY16) 2A06 (LY6) 2000 series aluminum plate is high hardness, which is the highest content of copper, about 3-5%.

Aluminum Coil Series1000 series 1000 series aluminum coil is also known as pure aluminum, which aluminum content is the most of all the series. Purity can reach more than 99.00%.
