1060 O Aluminum Strip Coil
1060 O Aluminum Strip Coil is a commercially pure aluminum material designed for operations that demand exceptional softness, clean surface quality, and reliable formability. With an aluminum content of at least 99.60%, it offers excellent resistance to atmospheric corrosion, strong thermal and electrical conductivity, and smooth processing during bending, stamping, spinning, and deep drawing.
The O temper indicates a fully annealed condition. This soft temper gives the strip low hardness and high elongation, allowing manufacturers to create complex parts with reduced cracking risk. It is widely selected for electrical components, lamp caps, cookware parts, decorative trim, cable shielding, heat-transfer components, packaging, and formed industrial accessories.
Material Character and Production Value
1060 aluminum belongs to the 1000-series aluminum family. Unlike heat-treatable alloys, its strength is primarily controlled through cold rolling and temper selection. In the O temper, the coil has been annealed to restore ductility after rolling. This creates a material that performs especially well where shaping ability is more important than structural strength.
Its high-purity composition also supports stable conductivity and corrosion resistance. For projects requiring a soft, economical, and easily fabricated metal strip, 1050 / 1060 Aluminum Strip provides a practical material route for many production environments.

Processing Advantages
The main strength of 1060 O Aluminum Strip Coil is its calm behavior during fabrication. The soft temper allows the strip to follow tooling shapes without excessive springback. It can be punched into small profiles, rolled into channels, spun into circular parts, or drawn into shallow and moderately deep shells.
For stamped items, smooth burr-controlled slit edges help prevent tearing and improve die life. For polished or decorative parts, a clean and uniform surface supports anodizing, brushing, embossing, coating, or lamination. The material can also be joined through TIG welding, MIG welding, resistance welding, riveting, folding, and mechanical fastening.
Because pure aluminum is relatively soft, 1060 O temper is not normally chosen for load-bearing structures, highly stressed brackets, or applications requiring high wear resistance. Where greater strength is needed while retaining good corrosion performance, 5052 Aluminum Strip may be a more suitable alternative.
Common Application Areas
| Application Area | Typical Parts | Why 1060 O Strip Performs Well |
|---|---|---|
| Lighting | Lamp caps, reflector parts, LED housings | Deep drawing ability and reflective surface potential |
| Electrical systems | Busbar accessories, transformer layers, cable shielding | Good conductivity and low weight |
| Cookware and appliances | Pot components, appliance trim, heat shields | Easy forming and efficient heat transfer |
| HVAC equipment | Fin stock, duct accessories, insulation facing | Corrosion resistance and thermal response |
| Packaging | Closures, caps, seals, decorative bands | Softness supports pressing and embossing |
| Construction finishing | Edge trim, flashing, ceiling accessories | Light weight and outdoor durability |
| Automotive interiors | Decorative strips, insulation layers, formed covers | Low mass and clean surface appearance |
| General fabrication | Stamped discs, spun shells, nameplates, channels | Broad processing compatibility |
Surface, Slitting, and Packaging Considerations
A successful coil selection involves more than alloy and thickness. Surface expectations should be stated before production, particularly for anodizing, polishing, printing, or exposed decorative applications. Typical requirements include no oil stains, no edge cracks, no severe roll marks, and controlled coil telescoping.
For narrow strips, consistent width tolerance and clean slit edges are important. Poor edge quality can lead to cracks during high-speed stamping or deep drawing. Coils may be supplied with moisture-resistant wrapping, protective paper, wooden pallets, steel bands, and reinforced outer protection to reduce transport damage.
