Aluminium Flat Bar Strip Plate Thickness 30mm-50mm grade 6061 T6 Lengths 500mm

Start with your load or span requirements. For structural brackets and gussets, thicker sections (40–50 mm) provide more bending resistance. For lightweight fixtures or jig plates where weight matters, 30–35 mm thickness is often sufficient. Width should match your bolt-hole pattern or contact surface. If you are unsure, consult a structural engineer or refer to your design drawings before ordering.

6061-T6 has a typical tensile strength of 260–310 MPa and yield strength of 240–276 MPa, making it suitable for many light-to-medium structural applications such as brackets, frames, and fixture plates. It is not intended as a substitute for structural steel in heavy civil or industrial applications. Always verify suitability against your specific load calculations.

6061-T6 aluminium forms a natural oxide layer that resists atmospheric corrosion well in most indoor and sheltered outdoor environments. In marine or highly acidic/alkaline environments, additional anodising or coating is recommended. The mill finish supplied here is uncoated, so surface treatment is at the buyer's discretion.

Yes. 6061-T6 welds well using MIG or TIG processes with 4043 or 5356 filler rod. Note that welding reduces the T6 temper in the heat-affected zone, lowering local strength. For critical joints, post-weld heat treatment or mechanical fastening may be preferable. Avoid welding to dissimilar metals without appropriate filler selection.

For cutting: a cold saw, band saw, or angle grinder with an aluminium-rated cutting disc works well. For machining: standard HSS or carbide end mills and drill bits are suitable. Use cutting fluid or WD-40 to reduce heat and prevent built-up edge. Tapping is straightforward with standard spiral-flute taps and aluminium-rated cutting oil.

This listing covers 500 mm lengths only. The variant selector lets you choose from a wide range of thickness-by-width combinations within that fixed length. If you need a different length, please contact us to confirm availability of custom cuts.

Square sections (e.g., 32×32 mm, 35×35 mm, 40×40 mm) offer equal stiffness in both axes — useful for posts, standoffs, and symmetric brackets. Rectangular sections (e.g., 35×100 mm, 40×80 mm) are stiffer in the wider direction, making them better suited for beams, rails, and plates where bending load acts in one primary direction. Choose based on your load orientation.
