◉ PRODUCT SPECIFICATION

1. Select Alloy & Temper

This is the foundation for defining product performance.

Alloy Series	Recommended Grades	Key Characteristics	Typical Applications
1000 Series (Pure Al)	1060, 1100	Excellent corrosion resistance, conductivity, formability	Chemical linings, reflectors, electrical components, decorative trim
3000 Series (Al-Mn)	3003, 3005	Most Common Series, good strength, corrosion resistance, formability	Ceilings & walls, cookware, blinds, HVAC heat exchangers
5000 Series (Al-Mg)	5052, 5083	High Strength, Excellent Marine Corrosion Resistance, good weldability	Shipbuilding, automotive body panels, tankers, engineering structures
6000 Series (Al-Mg-Si)	6061, 6082	High Structural Strength, heat-treatable, good all-around performance	Truck frames, robotic arms, rail transit, aerospace components

Temper Guide:

O (Annealed): Softest state, optimal ductility for deep drawing.
HX4 (e.g., H14/H24): Half-hard, balances strength with formability. Versatile.
HX8 (e.g., H18): Full-hard, high strength for applications requiring minimal bending.
T6 (Solution Heat-Treated & Aged): Highest strength via heat treatment for critical structures.

2. Dimensions & Tolerances

We provide precise, custom slitting services.

Thickness
- Range: 0.1mm - 10.0mm

Width
- Range: 100mm - 2500mm (Custom ultra-wide available)
- Tolerance: Precision slitting within ±0.5mm.
Inner Diameter (I.D.)
- Standard Options: 405mm (16"), 505mm (20"), 508mm (20"), 610mm (24")
- Custom Available: Tailored to your uncoiling equipment.
Coil Weight & Outer Diameter (O.D.)
- Max. Coil Weight: Up to 25 tons, reducing joints and boosting your efficiency.

3. Mechanical Properties (Typical Values)

Alloy/Temper	Tensile Strength (MPa)	Yield Strength (MPa)	Elongation (%)
1060 O	60 - 95	15 - 25	≥ 25
3003 H14	140 - 180	115 - 150	≥ 8
