There are many kinds of stainless steel

Brand: there are many kinds of stainless steel. Austenitic stainless steel (1Cr18Ni9Ti) Japanese Standard JIS (SUS) is commonly used in sheet metal processing

  1. aluminum plate: aluminum is a silver white light metal with good thermal conductivity, conductivity and ductility. Pure aluminum has low strength and cannot be used as structural materials. Aluminum alloy plates are generally used in sheet metal processing. According to the content of alloy elements, aluminum plates can be divided into 8 series, including 1000 series, 2000 Series ~ 8000 Series, and 2000 series, 3000 series and 5000 series are commonly used. 2000 series is a kind of copper aluminum alloy, which is characterized by high hardness, also known as hard aluminum; It can be used as various medium strength parts and components. 3000 series is a kind of manganese aluminum alloy with good antirust performance, so it is also called antirust aluminum; 5000 Series is a kind of magnesium aluminum alloy, which is mainly characterized by low density, high tensile strength and high elongation. Under the same area, the weight of aluminum magnesium alloy is lower than that of other series.

Commonly used brands include 3A21 (old brand LF21), 5A02 (old brand LF2) and 2A06 (old brand LY6)

  1. copper plate, commonly known as pure copper, is purple in appearance. It has excellent conductivity, thermal conductivity, ductility and corrosion resistance, but it is expensive. It is mainly used as conductive and thermal conductive materials. It is generally used for parts that need to carry high current on the power supply. Red copper has low strength and can not be used as structural parts.

Brand: T1, T2, T3

3.brass plate, brass is a copper zinc alloy with high strength and excellent cold and hot workability, but it is easy to produce corrosion cracking, relatively cheap and widely used.

Common brands: H59, H62, H70
