Aluminium Plates — Overview
Aluminium plate is flat-rolled aluminium above roughly 6 mm in thickness. Where sheet is chosen for forming and panelling, plate is chosen for load, wear and machining — it holds tolerance, resists deflection and can be milled, drilled and tapped like a solid block while weighing about a third of the equivalent steel.
Kumar Aluminium supplies plate to heavy engineering workshops, tooling and mould makers, marine yards, defence suppliers and structural fabricators across Mumbai and India. Our range covers utility grades from Hindalco, Jindal and Balco alongside an imported range that brings the high-strength 5000, 6000, 7000 and 2000 series into local stock.
Why buyers specify aluminium plate
- Dimensionally stable in stress-relieved T651 tempers
- About one-third the weight of steel plate
- Weldable in 5000-series and most 6000-series grades
- Non-magnetic and non-sparking
- Machines cleanly at high feed rates
- Corrosion-resistant without coating in most grades
- Retains toughness at cryogenic temperatures (5083)
- Fully recyclable

Aluminium Plate Sizes & Thickness Range
Plate is stocked in the same footprint sizes as sheet, with imported material arriving predominantly in the 1250 × 2500 mm format. Thickness runs from 6 mm to 200 mm.

Weight formula: plate weight in kg = length (m) × width (m) × thickness (mm) × 2.71. A 1220 × 2440 mm plate at 25 mm weighs about 201.7 kg.
Cutting, Machining & Documentation
Plate rarely leaves the yard in its full size. These are the processing services included with a plate order.
Processing available
- Saw cutting to finished dimensions
- Custom plate sizes on request
- Cutting as per customer drawing
- Machining support for heavy sections
Documentation
- Material Test Certificate on selected grades
- Brand and heat number traceability where available
- GST-compliant invoicing on every order
- Dispatch documentation for pan-India delivery
Tip: for machined parts, ask for a T651 temper rather than plain T6. The stretch stress-relief keeps the plate flat once material is removed, which saves re-machining later.

Aluminium Extrusions
Three decisions cover most plate specifications. If you are unsure, describe the part and its service conditions and we will suggest a grade.
1. Is the part machined or welded?
Machined parts should be 6061-T651, 6082-T651 or 7075-T651 — the stress-relieved tempers stay flat. Welded structures are better served by 5083-H111 or 5754-H111, which retain strength across the weld far better than heat-treated 6000-series grades.
2. What is the service environment?
For seawater and coastal exposure choose 5083, 5086 or 5754. For general industrial use 6061 and 6082 are ample. Avoid 2014, 2024 and 7075 in unprotected outdoor service — their copper and zinc content reduces corrosion resistance and they need coating or anodising.
3. How much load is it carrying?
For light brackets and non-critical parts the utility grades from Hindalco or Jindal are cost-effective. For genuine structural load go to 6082-T651. Where strength is the deciding factor and cost is secondary, 7075-T651 is the strongest plate we stock.
