What are the key mechanical properties of 1060 H24/H14 aluminum sheets with mill finish?
1060 aluminum in H24/H14 tempers offers a balance of moderate strength and good formability, with typical tensile strength ranging from 85-125 MPa. The H24 temper provides a semi-hard state suitable for bending, while H14 offers slightly higher hardness. Mill finish ensures a uniform, non-reflective surface ideal for industrial applications. These sheets maintain excellent electrical and thermal conductivity due to 99.6% aluminum purity. The blue PVC film protects against scratches during transportation and fabrication.
Why choose blue PVC film protection instead of other options?
Blue PVC film is highly visible, making it easy to detect and remove before processing. It provides superior moisture and abrasion resistance compared to paper or PE films. The adhesive is designed to leave no residue upon removal, preserving the mill finish. This film withstands UV exposure during outdoor storage. Cost-effectiveness and reusability make it a preferred choice for industrial suppliers.
What are the typical applications of 1060 mill finish aluminum sheets with PVC film?
Common uses include electrical enclosures, signage backplates, and heat sink components due to excellent conductivity. The material is favored for chemical equipment linings because of its corrosion resistance. Architects specify it for decorative cladding where a uniform matte appearance is desired. Manufacturers of cookware and lighting fixtures value its formability. The PVC-protected version ensures damage-free delivery to these end-users.
How does 1060 compare to 3003 or 5052 alloys for sheet metal applications?
While 3003 offers better strength (20-40% higher tensile) and 5052 provides superior corrosion resistance, 1060 excels in electrical/thermal applications requiring >99% purity. It's more economical for non-structural parts not needing alloy enhancements. The mill finish on 1060 achieves better surface consistency than alloyed alternatives. However, it lacks the weldability of magnesium-containing alloys like 5052.
What are the standard specifications and tolerances for these sheets?
Thickness typically ranges from 0.2mm to 6mm with ±0.02mm precision for thin gauges. Widths up to 1500mm comply with ASTM B209 or EN 485 standards. The H24 temper hardness reaches 30-40 HV on the Vickers scale. Flatness tolerances are ≤1mm/m for sheets under 3mm thickness. PVC film thickness usually measures 0.05-0.1mm with 180° peel adhesion ≥5N/cm.
