As a typical representative of industrial pure aluminum, the technical characteristics of 1100 Aluminum Coil can be summarized as the following core advantages, which are suitable for fields with high requirements for formability, corrosion resistance, and lightweight:
- Chemical composition and basic properties
High purity aluminum matrix: aluminum content ≥ 99.0%, total impurities ≤ 0.15%, ensuring material uniformity and stability.
Low density: The density is only 2.71g/cm ³ (about 1/3 of steel), significantly reducing structural weight and improving energy efficiency.
Non heat treatment strengthening: By cold working (such as rolling, stretching) to enhance strength, plasticity can be restored after annealing. - Outstanding physical performance
Excellent conductivity and thermal conductivity:
The conductivity reaches 59% IACS (International Annealed Copper Standard), suitable for power transmission (such as cables and busbars) and electronic heat dissipation (such as heat sinks and motor casings).
The thermal conductivity is about 237W/(m · K), which quickly conducts heat and ensures stable operation of the equipment.
Good corrosion resistance:
The surface is prone to forming a dense oxide film (Al ₂ O ∝), which resists corrosion from the atmosphere, water, and most organic solvents.
Stable in media such as seawater, dilute nitric acid, sulfuric acid, etc., but avoid environments with chloride ions (such as saltwater). - Excellent processing performance
Cold processing adaptability:
Cold rolling, cold drawing, stamping and other processes can produce thin plates, strips, foils (thickness 0.02mm-12mm), and are not easily cracked during the processing.
Typical cold work hardening effect: The tensile strength increases from 95 MPa in the annealed state to 110-136 MPa in the machined state.
Hot processing flexibility:
The forging temperature range is 350-450 ℃ to avoid low-temperature brittleness or high-temperature grain coarsening.
Support extrusion, stretching and other processes to produce pipes and profiles (such as door and window frames, building structural components).
Excellent welding performance:
Compatible with various methods such as gas welding, argon arc welding, and resistance welding, the welding joint has high strength and low risk of cracking.
Suitable for manufacturing large structural components (such as storage tanks, pipelines) and complex assemblies. - Diversity of surface treatment
Anodizing: forms a 10-25 μ m oxide film, enhancing corrosion resistance, wear resistance, and surface hardness, while achieving a colorful appearance.
Spray treatment: Increase color selection and weather resistance to meet the needs of building decoration (such as curtain walls, ceilings) and signage.
Polishing treatment: Obtain a mirror effect and enhance the aesthetic appeal of products (such as clock surfaces and reflective devices). - Widely applicable fields
Electronic appliances: heat sinks, capacitor casings, wire conductors, utilizing conductivity and thermal conductivity to ensure equipment performance.
Packaging industry: aluminum foil, cans, bottle caps, rely on corrosion resistance and sealing to extend the shelf life of food.
Architectural decoration: curtain walls, doors and windows, sun panels, combined with corrosion resistance and plasticity to achieve complex shapes.
Chemical equipment: storage tanks, pipelines, reactors, operate stably in corrosive media.
Transportation: Automotive components (such as wheels and transmission systems), ship components, reduce weight and improve fuel efficiency. - Economy and Environmental Protection
Cost effectiveness: The raw material cost is lower than most alloys, the processing energy consumption is low, and the comprehensive cost advantage is significant.
Recyclability: The aluminum recycling rate is as high as 95%, which meets the requirements of green manufacturing and circular economy.
