Product Overview:
3000 series aluminum-coated color coil is made of aluminum-manganese alloy (such as 3003 and 3004) as the base material, and the surface is cleaned, chemically converted, and coated with PVDF or PE color coating, which has the lightweight, corrosion resistance and decorative protection function of aluminum. With a typical thickness of 0.2mm-1.5mm, a width of up to 1500mm and a roll weight of 3-10 tons, it is the preferred material for construction, packaging and industrial fields.
1.Core Benefits & Features:
Material performance advantages
High Strength & Formability:
The tensile strength of 3003 aluminum alloy (containing 1.2% manganese) is 145MPa, which is 30% higher than that of pure aluminum (1 series), and is suitable for deep drawing and stretching processing (such as tanks and complex structural parts).
3004 aluminum alloy (containing 1.2% manganese + 1% magnesium) has higher strength (tensile strength 180MPa), which is suitable for load-bearing scenarios (such as building curtain wall skeleton).
Corrosion Resistance:
Aluminum-manganese alloy substrate + coating double protection, salt spray test ≥ 1000 hours (ASTM B117), suitable for high-corrosion environments such as coastal, chemical industry, etc.
Lightweighting:
The density is 2.73g/cm³, which is only 1/3 of steel, and the transportation and installation costs are reduced by 20%.
2. Surface treatment and functionality
Coating Diversity:
PVDF coating: UV resistant, chemical resistant, color retention for more than 15 years (RAL/Pantone color optional).
PE coating: economical for indoor applications (e.g. home appliance panels) with matte, pearlescent effects.
Special functional coatings: antimicrobial (ISO 22196), self-cleaning (lotus leaf effect), conductive (EMI shielding).
Processing Adaptability:
It supports slitting, stamping, and roll forming, and is compatible with automated production lines (such as continuous roll coating process).
3. Environmental protection and economy
100% recyclable: The energy consumption of aluminum recycling is only 5% of that of primary aluminum, which is in line with the EU's Green Deal carbon neutrality goal.
