Aluminum Coils
Aluminum Coils
Aluminum coil is a rolled product available in a continuous strip form, featuring both an inner diameter (ID) and an outer diameter (OD).
The ID ranges from 50 mm to 1000 mm. The aluminum alloy grades include 1xxx, 2xxx, 3xxx, 4xxx, 5xxx, 6xxx, 7xxx, and 8xxx series, with the most common grades being 1050, 3003, 6061, and 5251.
The thickness of these coils ranges from 0.045 mm to 80 mm, and the width ranges from 60 mm to 2650 mm.
Standard widths for aluminum coils are 800 mm, 1000 mm, 1250 mm, 1450 mm, and 1500 mm.

Features of Aluminum Coils
1. Good Temperature Resistance
Aluminum has a melting point of 660 degrees Celsius, making it suitable for use at general temperatures well below this point.
2. Excellent Corrosion Resistance
Its surface oxide film is tightly adhered, providing robust protection against oxidation, acids, alkalis, corrosion, decay, and UV rays.
3. Uniform and Long-lasting Color
Aluminum surfaces are soft and colorful, avoiding the inconsistencies of traditional spraying methods. This ensures that even large surfaces maintain a consistent, long-lasting, and fresh appearance.
4. High Strength and Rigid Joints
The combination of rigidity and toughness allows for free cutting, slitting, arcing, balancing, drilling, joint fixation, and edge compression molding.
5. Environmental Protection
Aluminum resists yellowing and uses chromium-free treatment to prevent discoloration. The roller paint contains active chemical molecules that form a protective layer on the surface. These molecules are stable, making the material easy to recycle and environmentally friendly.
Different Aluminum Coils Applications & Useage
Aluminum coils are versatile and can be used for a variety of applications, including:
– Truck bodies in the transport industry
– Clad aluminum coil for heat transfer and insulation in the building industry
– Utensil manufacturing
– Automotive components
– Heat transfer applications (fin material, tube material)
– Solar reflective films
– Building exteriors
– Interior decoration (ceilings, walls, etc.)
– Furniture cabinets
– Elevator decorations
– Signs, nameplates, and bag making
– Automotive interior and exterior decoration
– Household appliances (refrigerators, microwave ovens, audio equipment, etc.)
– Consumer electronics (mobile phones, digital cameras, MP3 players, USB drives, etc.)
Aluminum Coils: The Ultimate Guide
Multiple industries utilize aluminum coils for various applications, including automotive, construction, heat transfer, pharmaceutical, electrical, and food sectors.
Aluminum often outperforms other materials in many cases due to its advantageous properties.
Aluminum coils can be provided with a standard mill finish or can be customized with brushed, checkered, color-coated, satin-finished, or anodized surfaces. Aluminum sheets or foil can be cut into coils according to client specifications.
So what’s the grade? What’s the production process of these strips?
In this guide, we will show you details about all.
What Are Aluminum Coils?
Aluminum coil can be produced either from aluminum ingots or other forms of raw aluminum through cold rolling or direct casting, or from a smelting process directly through rolling, known as continuous casting. These sheets of rolled aluminum are then coiled around a core, making them easier to ship and store compared to aluminum in sheet form. Aluminum coils are used to manufacture a vast range of components across numerous industries.
Pure aluminum is too soft for most manufacturing applications, so aluminum coils are typically made as alloys. These alloys consist of at least two or more elements, with aluminum being one of them. The Aluminum Association administers a four-digit numerical system to identify aluminum alloys for sheet products. When alloyed with other metals, aluminum’s mechanical and other properties can be customized to meet specific requirements for strength, formability, and other characteristics.
Aluminum coil is available in various lengths, widths, and thicknesses, often referred to as “gauge.” The exact dimensions are determined by the size of the components being made and the manufacturing process used. Several surface finishes are available, including mill, matte, and bright. The selection depends on the use and desired appearance of the finished part.
