6061 T6 T651 Medium Thick Aluminum Plate 6-25mm Flatness Controlled for Mold Base Machining

Rolled from 6061 magnesium-silicon alloy, solution heat treated, artificial aged and stretched to T651 to release internal stress. Supplied in 6-25mm thickness with controlled flatness, for mold bases, fixture plates, jig plates and precision tooling that must stay flat after heavy machining.

• Stable after machining: T651 stretch relieved plate holds flatness through sawing, milling and drilling.
• Controlled flatness: typically 2mm per metre at 6-10mm and 3mm per metre at 12-25mm.
• Consistent machinability: fine grain and uniform hardness give clean edges and predictable tool life.
• Strength with corrosion resistance: 310MPa tensile, easy to anodise.
• Ready to use: saw cut to size with square edges within 0.5mm per 100mm.

• Mold and die: injection mold base, cavity and core backing plates, ejector and clamp plates, trim dies, prototype tooling.
• Fixtures and inspection: CNC fixture plates, welding and assembly jigs, CMM and vision checking fixtures, modular grid plates.
• Automation and machinery: guide rail and servo motor mounting plates, robot end effector plates, machine frames, guarding, packaging machine change parts.
• Electronics and laboratory: equipment frames, stage and vacuum chamber support plates, heat sink and cold plate bases, optical benches.
• Hydraulic and energy: manifold blocks, valve bodies, cylinder end plates, solar tracker and battery pack structural plates.
• Transport and heavy equipment: automotive welding fixtures, truck body and chassis reinforcement, rail interiors, marine fittings, aerospace ground support tooling.
• Construction and signage: curtain wall brackets, structural connection plates, sign frames, stage floors, workshop benches.

• Size: width 100-2600mm, length 500-6000mm, cut to size from one piece.
• Temper and tolerance: T6, T651, T4 or O; thickness in 0.5mm steps to ASTM B209, or plus or minus 0.1mm on machined plate.
• Surface: mill finish, PVC film, clear or hard anodising, chromate conversion, blasting or brushed finish.
• Machining: edge milling, chamfering, drilling, tapping, counterboring, pockets and steps from your DWG, DXF or STEP files, general tolerance plus or minus 0.1mm.
• Marking and packing: laser marked part and heat number, logo and labels, sets packed by machine number for automated lines.

• Alloy, temper, thickness and flatness grade advice based on your load and machining process, with drawing review before production.
• Quotation with price, lead time and packing details within 24 hours.
• Mill test certificate, dimensional and flatness report per batch; SGS, BV, TUV or Intertek inspection on request.
• Export documents including invoice, packing list, certificate of origin and Form E or Form A, plus photo and video updates at each production stage.
• Claims for dimension, flatness or surface defects handled within 30 days of arrival; OEM branding and confidential handling of your drawings.

• Packing: plastic film with VCI anti corrosion paper, fumigated seaworthy pallet, interleaved plates, steel strapping both ways with corner protectors, about 2 tons per pallet; plywood cases for small cut pieces.
• Loading: 20-25 tons per 20GP, 22-26 tons per 40GP or 40HQ, LCL from 1 ton.
• Delivery: stock sizes 7 working days, cut to size and machined orders 15-25 days after order confirmation; loading at Qingdao, Tianjin or Shanghai.
• Terms: FOB, CIF, CFR, CNF and DDP for selected destinations, with documents and loading photos sent before departure.
