3003 H14 aluminum coil is a versatile and reliable material choice. Its advantages are high cost-effectiveness and balanced comprehensive performance, suitable for a variety of industrial and commercial applications, especially for scenarios with medium strength, corrosion resistance and formability requirements.
1. Material performance advantages: lightweight + high corrosion resistance + strength balance
- Lightweight and strength
Density is only 2.73 g/cm³ (about 1/3 of steel), which significantly reduces the weight of the end product;
Tensile strength is 120–185 MPa, and yield strength is ≥85–145 MPa, which is about 10% higher than the pure 1000 aluminum series, and meets the structural bearing requirements while being lightweight.
Applicable scenarios: new energy vehicle battery shell (weight reduction of 20% + improved endurance), aviation and ship components.
- Excellent corrosion resistance
Manganese (content 1.0–1.5%) forms a dense oxide film, which has much better corrosion resistance than carbon steel in humid and salt spray environments, and has passed the 3000-hour salt spray test (such as photovoltaic frame applications) 4810;
Natural anti-rust properties, can be used in humid environments such as air conditioners, refrigerators, and ships without additional coating.
- Excellent thermal and electrical properties
The thermal conductivity reaches 237 W/(m·K), which is 15% higher than ordinary aluminum, suitable for radiators and electronic component shielding covers;
Electrical conductivity 41–55% IACS, suitable for conductive parts (such as battery housings).
2. Processing advantages: high efficiency + low cost + high yield
- Excellent deep drawing and formability
The material is soft and ductile (elongation 8–25%), and can be stretched into complex structures (such as battery aluminum shells) in one piece, reducing welding seams and improving sealing;
Support 3D curved surface processing (automobile panels, building curtain walls), reducing scrap rates.
- Friendly to welding and surface treatment
The boiling points of manganese and aluminum are close, the element burnout is low during welding, and the weld strength reaches 98% of the parent material, ensuring the structural integrity;
The surface is suitable for fluorocarbon spraying, anodizing and other processes, and the weather resistance is more than 10 years without fading (CE certification passed by the EU).
3. Diversity of application scenarios: covering high-growth industries
- New energy vehicles: power battery housings, lightweight body parts. Reduce weight by 20%+, increase endurance by 12%
- New energy: photovoltaic frames, energy storage battery boxes, hydrogen storage bottle liners, salt spray resistance 2000h+, life span 25 years
- Architecture: curtain walls, roofs, fireproof partitions. Wind pressure resistance, fireproof grade A, beautiful and durable
- Packaging: food cans, medical foils (thickness 0.006mm), chemical containers High barrier, corrosion resistance, FDA certified
- Electronics: radiators, conductive housings Excellent thermal/conductive properties, replacing copper materials to reduce costs.
