Classification Of Aluminum Alloy Sheets By Chemical Composition

 

1xxx Series Pure Aluminum AlloyAluminum content reaches over 99%, nearly no other alloy elements added. Features outstanding electric and thermal conductivity, good corrosion resistance and ductility. Typical grades include 1050, 1060, 1100. Mostly used for conductive parts, heat dissipation panels and common decorative materials.

2xxx Series Copper Alloy AluminumMain alloying element is copper. High strength and hardness, favorable cutting and welding performance, while corrosion resistance is relatively ordinary. Representative grade 2024. Widely applied in aerospace parts and high-strength structural components.

3xxx Series Manganese Alloy AluminumManganese serves as major additive. Balanced rigidity and anti-rust ability, easy to process and form. Classic grade 3003. Commonly made into anti-rust shells, kitchen utensils and packaging plates.

4xxx Series Silicon Alloy AluminumSilicon is the key alloy element. Low melting point, excellent wear resistance and welding performance. Suitable for welding wires and wear-resistant mechanical accessories.

5xxx Series Magnesium Alloy AluminumMagnesium dominated composition. Excellent corrosion resistance and tensile toughness, lightweight property prominent. Common grades 5052, 5083. Ideal for ship accessories, fuel tanks and outdoor engineering plates.

6xxx Series Magnesium-Silicon Alloy AluminumCompound addition of magnesium and silicon. Comprehensive performance balanced, can be heat treated for strength improvement. Typical grade 6061. Versatile for construction profiles, mechanical parts and daily hardware.

7xxx Series Zinc Alloy AluminumZinc is the main alloy component. Top-level strength among aluminum alloys, high bearing capacity. Representative grade 7075. Primarily used for aviation, mold manufacturing and heavy load structural parts.

8xxx Series Mixed Other ElementsDiverse auxiliary elements added. Covers special performance aluminum sheets for heat insulation, brazing and other customized functional scenes, applied in special industrial manufacturing fields.
