Aluminum Profiles & Extrusions Supplier — Custom & Standard Shapes for Construction, Industry & Electronics

6061 and 6063 are both 6xxx-series alloys, but they differ in strength and extrudability. 6061-T6 offers higher tensile strength (≥260 MPa vs ≥215 MPa for 6063-T6), making it ideal for structural and load-bearing applications. 6063 extrudes more easily, produces a smoother surface finish, and is preferred for architectural applications like window and door frames where appearance matters. 6063 is also more cost-effective for complex cross-sections.

For standard profiles, our MOQ is typically 500 kg. For custom profiles requiring a new extrusion die, the MOQ is 1 ton. Die costs range from $200-$2,000 depending on complexity. We also accept sample orders (50-100 kg) for new customers to evaluate quality before placing production orders.

Lead time depends on whether a new die is needed:
• Standard profiles (existing die): 7-15 days
• Custom profiles (new die): 20-30 days (includes die design 3-5 days, die manufacturing 5-7 days, sample extrusion 2-3 days, and production 7-10 days)
• Expedited service: Available for urgent orders with surcharge
Shipping time: 7-15 days by sea to most international ports.

We offer six main surface treatment options:
1. Mill finish — natural silver, lowest cost
2. Anodizing (8-25 μm) — silver, black, champagne, bronze, gold, custom colors
3. Powder coating (40-120 μm) — any RAL color, matte/glossy/textured
4. Electrophoresis (20-30 μm) — clear, black, bronze
5. Wood grain transfer — oak, walnut, cherry, teak, pine
6. PVDF coating (25-40 μm) — premium weather resistance for facades

Our standard tolerances conform to ASTM B221 and EN 755:
• Wall thickness: ±0.15-0.30 mm
• Width/height: ±0.30-0.70 mm
• Angles: ±1.0-2.0°
• Twist: 0.5-2.0° per meter
• Straightness: 0.5-1.5 mm per meter
For precision applications, we offer high-precision tolerances: wall thickness ±0.05 mm, angles ±0.3°. Please specify your requirements in the RFQ.

Yes! Custom extrusion is our core capability. Send us your drawing (PDF, DWG, DXF, or STEP) and we will:
1. Review feasibility and recommend the optimal alloy and temper
2. Design the extrusion die (3-5 days)
3. Provide a quote including die cost and unit price
4. Produce sample profiles for your approval (2-3 days after die completion)
5. Proceed to mass production upon approval
Maximum circle size: 350 mm. Minimum wall thickness: 0.4 mm.

Our products comply with international standards and carry the following certifications:
• ISO 9001:2015 — Quality Management System
• ASTM B221 — Standard for aluminum-alloy extruded bars, rods, profiles, and tubes
• EN 755 — European standard for aluminum extrusions
• GB/T 6892 — Chinese national standard
• JIS H4100 — Japanese industrial standard
• CE marking available for construction products
• RoHS compliance for electronics applications
Mill Test Certificates are provided with every shipment.

Yes, we offer full value-added processing services:
• CNC cutting — precision cutting to length (±0.5 mm)
• Drilling & tapping — holes, threads, and mounting features
• Milling & slotting — custom features and pockets
• Punching — high-volume hole patterns
• Bending — profiles can be bent in T4 temper before aging
• Welding — TIG and MIG welding for assemblies
• Assembly — sub-assembly and kitting
This eliminates the need for secondary processing at your facility, reducing cost and lead time.

Our export packaging protocol ensures safe delivery:
1. PE protective film on all visible surfaces
2. Kraft paper wrap for moisture protection
3. Steel strap bundling with separator cards between layers
4. ISPM-15 wooden crates (heat-treated, fumigation-free)
5. Desiccant packets to control humidity
6. QR code labels for traceability
Each crate is loaded and secured in 20GP or 40HQ containers. Shipping terms: FOB Shanghai/Ningbo, CIF, or DDP.

Both T5 and T6 are precipitation-hardened tempers, but the process differs:
• T5: The profile is cooled from extrusion temperature (air or water mist) and then artificially aged in a furnace. No separate solution heat treatment. Lower cost, slightly lower strength.
• T6: The profile undergoes solution heat treatment (full re-heating to 530°C, quenching, then aging). Higher strength and more consistent mechanical properties.
For 6063: T5 ≥160 MPa, T6 ≥215 MPa tensile strength. T5 is common for architectural profiles; T6 is preferred for structural applications.

Yes. For anodizing, we offer standard colors (silver, black, champagne, bronze, gold, titanium) and can match custom shades within ±1 ΔE tolerance. For powder coating, we can match any RAL color or Pantone reference, with matte, glossy, satin, textured, or metallic finishes. We provide color samples for approval before production. Minimum color match batch: 500 kg.
