What Is Aluminum Coil?
Aluminum coil is a continuous flat-rolled aluminum or aluminum-alloy product supplied in coil form for efficient storage, transportation and downstream processing.
Compared with individual sheets, coil material is particularly suitable for continuous production processes such as roll forming, stamping, profiling, slitting, insulation jacketing, roofing panel production and component fabrication.
The correct aluminum coil should be selected according to:
Required strength and formability
Corrosion exposure
Welding or brazing requirements
Surface appearance
Thickness and width tolerance
Downstream forming process
Applicable material standard
Coil handling and equipment limits

Aluminum Coil Alloy Selection Guide
1050 Aluminum Coil
1050 aluminum contains a high aluminum content and provides excellent formability, electrical conductivity and thermal conductivity.
Common tempers: O, H12, H14, H16, H18, H22, H24
Typical applications: electrical components, insulation jacketing, signs, reflectors, roofing and general forming.
Choose 1050 when high conductivity and easy forming are more important than structural strength.
1060 Aluminum Coil
1060 is commercially pure aluminum with good ductility, corrosion resistance and processing performance.
Common tempers: O, H12, H14, H16, H18, H22, H24
Typical applications: heat-transfer components, electrical products, roofing, insulation and formed industrial parts.
Choose 1060 for general-purpose applications requiring high purity and consistent forming.
3003 Aluminum Coil
3003 is an aluminum-manganese alloy offering greater strength than commercially pure aluminum while maintaining good formability and corrosion resistance.
Common tempers: O, H12, H14, H16, H18, H22, H24, H26
Typical applications: roofing, gutters, insulation jacketing, HVAC components, tanks, signs and general sheet-metal fabrication.
Choose 3003 for cost-effective forming applications requiring moderate strength.
3004 Aluminum Coil
3004 offers higher strength than 3003 while retaining good deep-drawing and forming performance.
Common tempers: O, H14, H16, H18, H19, H24
Typical applications: formed containers, building products, roofing components and industrial fabrication.
The exact temper should be selected according to forming depth and final mechanical-property requirements.
3104 Aluminum Coil
3104 is commonly selected for applications requiring a combination of strength, formability and stable rolling performance.
Common tempers: H19 and application-specific tempers
Typical applications: formed products, container stock and specialized manufacturing.
Thickness, surface and mechanical-property requirements should be confirmed before ordering.
3105 Aluminum Coil
3105 aluminum coil is frequently used for coated building products and general construction applications.
Common tempers: H14, H16, H18, H24, H26
Typical applications: roofing, wall cladding, gutters, shutters, ceilings and pre-painted aluminum products.
Choose 3105 when the material will be roll formed, coated or used in exterior building systems.
5052 Aluminum Coil
5052 is an aluminum-magnesium alloy known for good corrosion resistance, fatigue performance, weldability and forming capability.
Common tempers: O, H32, H34, H36, H38
Typical applications: marine components, transport equipment, electrical enclosures, fuel tanks, industrial covers and formed components.
Choose 5052 when higher strength and corrosion resistance are required without using a heat-treatable alloy.
5083 Aluminum Coil
5083 is a higher-magnesium aluminum alloy intended for demanding welded and corrosion-resistant applications.
Common tempers: O, H111, H112, H116 and H321, subject to product form
Typical applications: marine structures, transportation, tanks, welded assemblies and industrial equipment.
For marine or pressure-related projects, the required temper, inspection class, welding condition and governing standard must be confirmed before production.
6061 Aluminum Coil
6061 is a heat-treatable aluminum-magnesium-silicon alloy that combines strength, corrosion resistance, weldability and machining performance.
Common tempers: O, T4 and T6
Typical applications: structural components, transportation parts, industrial equipment, fabricated assemblies and machined components.
Availability depends strongly on temper, thickness and width. For flatness-critical or machining-intensive projects, sheet or plate may be more suitable than coil.
3003 vs 5052 vs 6061 Aluminum Coil
Choose 3003 When You Need:
Good forming performance
Moderate strength
Cost-effective material
Roofing or HVAC production
General corrosion resistance
Choose 5052 When You Need:
Higher strength than 3003
Better marine and atmospheric corrosion resistance
Good fatigue performance
Welding and forming
Transport or enclosure components
Choose 6061 When You Need:
Heat-treated mechanical strength
Structural performance
Machining capability
Welded frames or industrial parts
A T4 or T6 temper
Final alloy selection should be based on the required standard, temper, mechanical properties, forming process and service environment.
Mill Finish and Surface Options
Mill Finish
Standard rolled surface suitable for fabrication, forming, roofing, insulation and general industrial applications.
Degreased Surface
Oil and processing residues can be controlled when the material will be bonded, painted, laminated or further surface treated.
Protective Film
PE protective film may be applied to reduce scratching during handling, cutting and fabrication.
Coated Aluminum Coil

Embossed Surface
Stucco embossed or application-specific patterns may be supplied where improved appearance, rigidity or insulation-jacketing performance is required.
All non-standard surfaces should be confirmed using approved samples or technical specifications before mass production.
Aluminum Coil Processing Services
Precision Slitting
Master coils can be slit into narrower widths according to the customer's production line and component dimensions.

Aluminum Coil Weight Calculator
Use the following formula to estimate aluminum coil material requirements.
Weight in kilograms:
Weight = Thickness × Width × Length × 0.00270
Where:
Thickness is measured in millimeters
Width is measured in millimeters
Length is measured in meters
0.00270 is based on an approximate aluminum density of 2.70 g/cm³
Example:
1.0 mm × 1,000 mm × 1,000 m × 0.00270
= 2,700 kg
Estimated coil length:
Length = Weight ÷ Thickness ÷ Width ÷ 0.00270
The calculation is an estimate. Actual weight may vary according to alloy density, dimensional tolerance and weighing method.
