Aluminum Coil

Description

Aluminum coil is a kind of rolled material made of aluminum or aluminum alloy through rolling process, which has the characteristics of light weight, corrosion resistance and easy processing.
Classification
By alloy composition:
Pure aluminum coil: such as 1050, 1060, etc., with purity higher than 99%.
Aluminum alloy coil: such as 3003, 5052, 6061, etc., other elements are added to improve performance.
By thickness:
Thin aluminum coil: less than 0.2mm thick, used for packaging, etc.
Medium and thick aluminum coil: 0.2-6mm thick, used for construction, transportation, etc.
Thick aluminum coil: more than 6mm thick, used for heavy machinery, ships, etc.
By surface treatment:
Ordinary aluminum coil: no special treatment.
Coated aluminum coil: the surface is painted or coated.
Aluminum oxide coil: anodized to enhance corrosion resistance.
Process
Melting and casting: the aluminum ingot is melted and cast into billets.
Hot rolling: the billet is heated and rolled into thicker aluminum coils.
Cold rolling: The aluminum coil after hot rolling is further cold rolled to the required thickness.
Annealing: Annealing is performed after cold rolling to improve performance.
Surface treatment: Coating or oxidation treatment is performed as required.
Slitting: Cutting large aluminum coils into required widths.
Features
Lightweight: Low density, suitable for lightweight applications.
Corrosion resistance: The surface oxide film provides good corrosion resistance.
Easy processing: Easy to cut, stamp, weld, etc.
Electrical and thermal conductivity: Excellent electrical and thermal conductivity.
Recyclable: Can be recycled multiple times, environmentally friendly.
Uses
Packaging: Used for food and drug packaging, such as aluminum foil.
Construction: Used for roofs, walls, curtain walls, etc.
Transportation: Used in the manufacture of vehicles such as cars, trains, and airplanes.
Electronics: Used for electronic components such as capacitors and radiators.
Home appliances: Used in parts for home appliances such as refrigerators and air conditioners.
Industry: Used in industrial fields such as chemical equipment and storage tanks.
Summary
Aluminum coils are widely used in packaging, construction, transportation, electronics, home appliances and industry due to their light weight, corrosion resistance and easy processing.
