1070 Aluminum Coil

1070 Aluminum Coil Introduction and Key Performance Characteristics 
The 1070 aluminum coil is a type of 1-series high-purity industrial pure aluminum (with Al content ≥ 99.70%), which is an alloy that cannot be heat-treated for strengthening. It has core advantages such as high electrical and thermal conductivity, excellent plasticity, and good corrosion resistance. It is divided into cold-rolled coils (thin material, fine surface) and hot-rolled coils (thick material, high toughness). It is the mainstream base material for products such as stretching, reflective, electrical conductivity, and heat dissipation. 
I. Basic Information 
• Brand standard: GB/T 3190 1070, with Al content ≥ 99.70%, total impurities ≤ 0.30% 
• Common State 
◦ O state: Soft state, with high elongation, suitable for deep drawing/rotational forming 
◦ H12/H14/H18/H24: Semi-hard/ hard state, enhanced strength, suitable for bending/ conformal parts 
• Standard Specifications 
◦ Cold rolling: Thickness ranging from 0.15 to 3.0 mm, with a smooth surface and precise tolerances. 
◦ Hot rolling: Thickness range of 2.0 to 8.0 mm, good toughness, wide plate width, suitable for large-scale stretching. 
II. Core Physical and Mechanical Properties 
Mechanical properties (typical values) 
• O state: Tensile strength ≤ 130 MPa, yield strength ≥ 40 MPa, elongation ≥ 25%, not prone to cracking during bending or deep drawing 
• H14 State: Tensile strength ranging from 120 to 160 MPa, elongation rate ≥ 8%, balancing both molding and structural stability 
• H18 grade: Tensile strength ≥ 150 MPa, high hardness, suitable for shallow punching and shaped parts 
2. Physical Properties 
• Conductivity: ≈ 61% IACS. Excellent conductivity performance, suitable for power/electronic conductive components. 
• Thermal conductivity: ≈ 237 W/(m·K). High heat dissipation efficiency, suitable for heat dissipation components. 
• Density: Approximately 2.7 g/cm³, showing significant advantages in lightweighting. 
• Reflectivity: The surface has a high degree of purity and is smooth, with excellent reflective properties, suitable for lamps/optical reflectors. 
3. Process & Corrosion Resistance Performance 
• Formability: Excellent plasticity, easy for deep drawing, spinning, bending, stretching, and 180° bending without cracks. 
• Corrosion resistance: Excellent corrosion resistance in atmospheric, freshwater, and weakly corrosive environments. No additional protection is required. 
• Weldability: Regular welding methods (arc welding, spot welding, gas welding) are all acceptable, with no risk of thermal cracking. 
• Surface treatment: Easy to undergo anodic oxidation, polishing, spraying, printing. Excellent in decoration and protective properties.
