When you search for “China 6061 aluminum sheet,” you likely have a specific project in mind. Perhaps you need materials for electric vehicle battery trays, or maybe you’re sourcing stock for precision machining.
This guide covers what you actually need to know: specifications, pricing factors, and how to find a reliable supplier.
6061 is an Al-Mg-Si alloy. It offers medium strength, excellent weldability, and good corrosion resistance. That’s why it’s called the “universal aluminum plate” – it works across countless applications.
Chinese mills typically produce 6061 sheets in thicknesses from 0.3mm to 500mm. The standard size is 4×8 feet (1220x2440mm), but many manufacturers offer custom sizes up to 2600mm wide and 12000mm long.
– T6: The most common option. Heat-treated for high strength. Suitable for most structural parts.
– T651: T6 with added stretching to relieve internal stress. Ideal for precision parts requiring high flatness after CNC machining.
– O / H112: Annealed or as-hot-rolled condition. Best for applications needing deep forming.
The lowest price doesn’t always mean the lowest cost. Scrap from inconsistent quality, or production delays from late shipments – those hidden costs add up fast.
Ask for the MTR. A trustworthy supplier provides Mill Test Reports certifying chemical composition and mechanical properties per ASTM B209 or GB/T 3880 standards.
Know who you’re buying from. Is this a trader or the actual producer? Mills with complete production chains – hot rolling, cold rolling, heat treatment – control quality and delivery much better.
Other useful benchmarks:
– Lead time: Industry leaders deliver in 15-30 days for standard orders.
– Communication: Fast responses usually mean better service overall.
1. Raw Material (Aluminum Ingot) Prices
Aluminum sheet prices track LME or SHFE futures closely. Suppliers typically quote as “ingot price + processing fee,” or lock prices for a set period (like one week). Understanding this helps you time your purchases better.
2. Temper
T6 vs. T651 involves different processing steps. The processing fee varies slightly based on complexity.
3. Dimensions
Non-standard widths or lengths, or extremely thin or thick gauges, cost more. Production difficulty increases and yields change compared to standard 4×8 sheets.
4. Surface Requirements
Need protective masking for later stamping? Require ultra-high flatness? These specifications affect the final quote.
5. Order Quantity
– 3-5 tons: Typical trial order range.
– 20+ tons: Better volume pricing kicks in.
– Full container (~25 tons) or full coil: Most cost-effective option.
6061 aluminum sheet is used across many sectors.
New Energy Vehicles: For battery trays and skid plates. Its light weight helps extend vehicle range, while its corrosion resistance ensures durability.
Precision Machining: T651 temper is a cost-effective choice for CNC machining. It is widely used for phone casings, computer parts, and automation components.
Transportation: In body structures, ships, and containers.
Building & Decor: For curtain walls and ceilings.

Q: What’s the difference between 6061 and 6061 T6?
A: T6 is a temper of 6061. T6 has been heat-treated for higher strength. 6061 also comes in O or T4 tempers for different forming needs.
Q: What standard sizes do Chinese suppliers offer?
A: 4×8 feet (1220x2440mm) is most common. Many mills also customize up to 2800mm wide and 16000mm long.
Q: How long does delivery take?
A: Standard orders: 15-25 days. Large/custom orders: 30-45 days. Stock items can ship in 7-10 days.
Q: How do I verify quality?
A: Request the Mill Test Report. It should show chemical composition and mechanical properties per ASTM B209 or GB/T 3880.
