1050 H24 Aluminum Circle Disc

Title

What is 1050 H24 Aluminum?

1050 H24 aluminum refers to 1050 aluminum alloy in H24 temper, which means the aluminum alloy is strain-hardened and partially annealed to a condition halfway between the annealed (O) and full-hard (H28) states. In this state, the material gains moderate strength while retaining good ductility.

1050 aluminum circle discs belong to the 1 series of pure aluminum, with an aluminum content of 99.5%. It retains the silvery white glass and light weight of pure aluminum, as well as excellent weldability, ductility, surface reflectivity, corrosion resistance and electrical conductivity.

Advantages of 1050 H24 Aluminum Circle

High Purity: Belonging to the pure aluminum series, 1050 has an aluminum content of over 99.50%, ensuring excellent conductivity, thermal conductivity, and corrosion resistance.
Good Formability: In H24 temper, the circles combine moderate strength with excellent formability. This makes 1050 H24 aluminum circles highly suitable for stamping, deep drawing, bending, and spinning into complex shapes.
Corrosion Resistance: The natural oxide film formed on the surface of pure aluminum provides an effective barrier against atmospheric corrosion and moisture.
Excellent Anodizing Quality: When anodized, 1050 H24 aluminum circle discs offers an attractive surface finish with enhanced corrosion resistance and reflectivity.

Production Process of 1050 H24 Aluminum Circle

1. Raw Material Selection
High-quality aluminum ingots are processed into 1050 aluminum coils through hot and cold rolling. The raw materials must be pure and have a uniform microstructure.

2. Rolling Process

Hot Rolling: Aluminum ingots are heated to 500-530°C and rolled into initial slabs.

Cold Rolling: Further reduced to the required thickness (0.4-6.0mm) with excellent flatness.

3. Intermediate Annealing
To restore ductility and prevent cracking during stamping, cold-rolled sheets undergo annealing to soften the material while retaining sufficient strength.

4. Blanking into Circles
High-speed punching machines or circle cutting equipment cut the aluminum coils into round discs with diameters of 100-1000mm and thicknesses of 0.4-5mm.

5. Surface Treatment & Inspection

Processes include deburring, degreasing, and cleaning to ensure a smooth surface.

Online eddy current testing or surface scanning eliminates defects such as scratches, dents, or oxide spots.

6. Final Packaging
Products are packed with moisture-proof paper and wooden pallets to prevent scratches and oxidation during transportation.
