Aluminium Angle Unequal 25x12 is a 6060 T5 mill-finish aluminium L-profile with 25 x 12 mm unequal legs, supplied in a 1.6 mm thickness and 2165 mm length.
What it does
The unequal profile provides a wider and narrower leg for framing, edge protection, finishing trims and fabrication where a 25 x 12 mm section is specified. The alloy is used where corrosion resistance, weldability and a high strength-to-weight ratio matter.
Numbers that matter
- Leg dimensions: 25 x 12 mm unequal angle for offset edge and framing details.
- Thickness: 1.6 mm.
- Length: 2165 mm.
- Alloy and temper: 6060 T5.
- Finish: Mill finish, ready for preparation when a secondary finish is specified.
Where it fits
Suitable for general fabrication, vehicle and caravan body work, shopfitting and architectural framework applications where this section meets the project requirements.
Before installation or coating
- Dissimilar metals: Isolate the aluminium when fastening to dissimilar metals to reduce galvanic-corrosion risk.
- Treated timber: Avoid direct contact with green or treated timber.
- Secondary finishing: Degrease and prepare the mill-finish surface before anodising, powder coating or painting.
Frequently asked questions
Can these aluminium angles be used for vehicle body building?
Yes, 6060 T5 aluminium angles are well-suited for vehicle body construction. Their high strength-to-weight ratio allows for increased payload, and excellent weldability ensures secure, durable fabrication.
Are these angles suitable for outdoor use without further treatment?
Yes, 6060 T5 aluminium angles offer excellent inherent corrosion resistance for outdoor environments. While supplied in a mill finish, their natural properties prevent rust. For enhanced aesthetics or specific protection, anodising or powder coating can be applied.
What are the key benefits of using 6060 T5 alloy for these angles?
The 6060 T5 alloy provides an optimal balance of structural strength, ease of fabrication, and corrosion resistance. This temper ensures a high strength-to-weight ratio, excellent weldability, and good machinability, making it versatile for various construction and manufacturing needs.
