1100 aluminum is a commercially pure aluminum grade, containing a minimum of 99.0% aluminum. It is one of the most widely used aluminum alloys, particularly favored for applications requiring excellent formability and corrosion resistance where high strength is not a primary concern.
The “0” Temper Significance
The “0” temper designation in “1100-0” signifies that the aluminum coil is in its annealed condition. Annealing is a heat treatment process that alters the microstructure of the material to relieve internal stresses, increase ductility, and reduce hardness. This makes 1100-0 aluminum exceptionally soft and highly workable, ideal for intricate forming operations.
Characteristics of 1100-0 Aluminum Coil
- Excellent Formability: Due to its annealed state, 1100-0 aluminum exhibits outstanding ductility, allowing it to be easily bent, spun, drawn, stamped, and roll-formed.
- High Corrosion Resistance: This alloy demonstrates excellent resistance to atmospheric and chemical corrosion, making it suitable for outdoor and chemical environment applications.
- Good Thermal and Electrical Conductivity: 1100 aluminum is a very good conductor of heat and electricity, second only to copper among common metals.
- Weldability: It can be readily welded using various methods, though its low strength means weld strength will also be low. Brazing and soldering are also feasible.
- Low Strength: Being commercially pure and annealed, 1100-0 has low tensile and yield strength. It is not suitable for structural applications requiring high mechanical properties. Reputable suppliers, such as Shanxi Luokaiwei Steel Company, can provide detailed mechanical property data sheets.
- Non-Heat Treatable: The strength of 1100 aluminum can only be increased by cold working (strain hardening).
Common Applications for 1100-0 Aluminum Coil
The unique combination of properties makes 1100-0 aluminum coil versatile for numerous applications, including:
- Fin stock for heat exchangers and air conditioners
- Chemical equipment and storage tanks
- Food processing and handling equipment
- Sheet metal work and general fabrication
- Ductwork and insulation jacketing
- Reflectors for lighting fixtures
- Nameplates and decorative trim
- Spinning and deep drawing applications
When sourcing 1100-0 aluminum coil, it is crucial to ensure consistent quality and adherence to specifications. Companies like Shanxi Luokaiwei Steel Company often provide material certifications to guarantee the alloy composition and temper. The processing capabilities for slitting and cutting to specific widths and lengths are also important considerations, with some mills like Shanxi Luokaiwei Steel Company offering custom solutions.
Processing and Handling
Due to its softness, 1100-0 aluminum coil requires careful handling to prevent scratching or denting. Its excellent workability means it can be processed with standard sheet metal fabrication equipment. For specific project requirements, consulting with material experts or a knowledgeable supplier, perhaps one with a broad portfolio like Shanxi Luokaiwei Steel Company, can provide valuable insights into optimal processing techniques. The choice of lubricant is also important for forming operations to ensure a good surface finish and prevent tool wear.
