1, stainless steel SUS304: is one of the most commonly used stainless steel, because the Ni (nickel) is higher than Cr (chromium), quite corrosion resistance, temperature resistance, has a good mechanical properties, no heat treatment process hard bottom condition.

2, stainless steel SUS301: Cr (chromium) content is lower than SUS304, corrosion resistance is weak, but in the stamping parts processing can get very good tensile force and strength, ductility is good, often used to spring sheet, EMI shielding cover.

3, special stainless steel for pressure vessels "GB24511_2009_ stainless steel steel plate and steel belt for pressure equipment".

4, galvanized plate SECC: SECC electrolytic plate is divided into N material, P material, N material is mainly not for surface treatment, high cost, P material is used for spraying parts. SECC is a general cold-rolled steel coil, pickling, electroplating and various post-treatment processes. SECC not only has the mechanical properties and similar process properties of general cold-rolled steel sheet, but also has excellent corrosion resistance and art Deco appearance. For example, the main chassis is widely used in the SECC.

5, hot dip galvanized steel plate SGCC: hot dip galvanized steel coil refers to the semi-finished products after hot rolled pickling or cold rolling, after cleaning, annealing, immersed into the temperature of about 460℃ dissolved zinc tank, and the steel sheet coated with zinc layer, and then after quality leveling and chemical treatment. SGCC material is hard, worse than SECC material, with poor ductility (avoid deep drawing design), thick zinc layer and poor electric soldering.

6, cold rolled plate SPCC: mainly with electroplating and baking paint parts, low cost, easy to form, material thickness of 3.2mm.

7, hot rolled plate SHCC: material T≥3.0mm, also with electroplating, paint parts, low cost, but difficult to form, mainly used for flat parts.

8, copper: mainly with conductive materials, its surface treatment is nickel plating, chrome plating, or no treatment, the cost is high.

9, aluminum plate: generally with surface chromate (J11-A), oxidation (conductive oxidation, chemical oxidation), high cost, silver plating, nickel plating, through the surface anodic oxidation process can obtain the appearance of different colors.、

10, aluminum profile: complex section structure of materials, a large number of used in a variety of plug box. Surface treatment with aluminum plate.

11, magnesium alloy: characteristics: the lightest metal junction raw materials; high compressive strength, fatigue resistance, impact resistance, good flow, good antistatic effect; poor corrosion resistance, easy to oxidation burn out.

12, copper alloy: characteristics: conductive performance, thermal conductivity, corrosion resistance, good luster, simple plastic production and processing, easy electroplating process, coating process.

13, Aluminum alloy: characteristics: relatively light metal raw materials; good corrosion resistance, conductive performance and thermal conductivity; under the same total weight, Al conductive performance is 2 times higher than Cu, but the compressive strength and strength of pure aluminum are relatively low.

14, brass zinc alloy: mechanization performance is related to zinc content; usually zinc content does not exceed 50%. Characteristics: extensibility, good stamping processing, application in electroplating process, good resistance to seawater and air corrosion. But the body simply simple local corrosion. It is a copper-based alloy metal general name dominated by bronze tin alloy. Characteristics: better than the wear resistance of pure copper and brass: good process performance, corrosion resistance.
