FAQ
Most enquiries reduce to a small set of recurring technical questions.
01 What is 6061 aluminum sheet and plate?
6061 (EN AW-6061 / AlMg1SiCu) is a magnesium-silicon-copper 6xxx aluminum alloy. In the T6 / T651 temper it offers a balanced combination of strength, weldability, formability and corrosion resistance, and is one of the most widely used general-purpose structural aluminum alloys.
02 What is the typical thickness range supplied?
Sheet and plate are typically supplied from 0.5 mm up to approximately 150 mm, with thinner sheet, plate and cut-to-size plate subject to mill capability and order quantity.
03 What tempers are available for 6061 plate?
O (annealed), T4 / T451 (solution heat-treated), T6 / T651 (solution heat-treated and artificially aged) are the most common tempers for 6061 plate and sheet. Other tempers are available on request.
04 What is the difference between sheet and plate?
In aluminum product standards, plate generally refers to flat products at or above approximately 6.35 mm (1/4 in) thickness, while sheet covers thinner gauges. The applicable tolerances and delivery conditions differ accordingly.
05 Is 6061 plate suitable for welded fabrication?
Yes. 6061 is weldable using appropriate filler alloys (e.g. 4043 / 5356) and procedures. For heavily welded assemblies, T6 temper is typically supplied after welding rather than welded in the T6 condition, depending on the specification.
