Introduction of common sheet metal materials

Ordinary cold steel plate (SPCC):

The most commonly used material in sheet metal processing, iron gray luster, easy to scratch the surface and getting rusty. It generally needs to do surface treatment, such as dusting, painting, electroplating and so on.


Galvanized sheet steel (SECC):

Refers to the ordinary cold plate through the galvanized line of work, so that the surface of steel plate to produce a layer of galvanized. The electrolytic plate maintains the mechanical properties and approximate machinability of the common cold plate, and also increases the excellent corrosion resistance and decorative properties.


Stainless Steel Plate:

SUS304 is one of the most popular stainless steel, corrosion resistance, heat resistance, and has excellent mechanical properties; SUS301 with corrosion resistance slightly worse, but after cold processing can get good tensile properties and hardness, elasticity is better used for shrapnel and so on.

Stainless Steel has a gold-white luster, not easy to rust, and surface can be mirror, fog surface, drawing surface, etc. It usually to be decorative structural parts.


Aluminium alloy sheet:

Pure aluminum’s strength is very low, can not be used as structural materials, sheet metal processing generally use aluminum alloy plate, commonly used in 2000 series, 3000 series and 5000 series. The 2000 series is copper alloy, characterized by high hardness, also known as hard aluminum, can be used as medium strength parts and components; 3000 series is a kind of manganese and aluminum alloy, rust-proof, so also known as rust-proof aluminum; 5000 series is a kind of Mg-Al alloy, which is characterized by low density, high tensile strength and Aluminum alloy is not only lightweight but also has good corrosion resistance, conductivity and thermal conductivity, usually used as appearance parts and aviation parts.
