Aluminium 1100
Aluminium 1100 (often referred to as “pure aluminum”) is one of the most widely used grades of aluminum in various industrial and commercial applications. This grade is known for its excellent formability, corrosion resistance, and high thermal and electrical conductivity. It is particularly popular in industries such as food and beverage packaging, electrical, and chemical processing, where its excellent properties and cost-effectiveness make it the go-to material for many applications.
Key Features of Aluminium 1100
- High Purity: Aluminium 1100 is made up of approximately 99% pure aluminum, which contributes to its light weight and excellent corrosion resistance.
- Excellent Workability: Known for its outstanding formability, Grade 1100 can be easily bent, shaped, and welded, making it ideal for applications where high ductility and easy fabrication are required.
- Corrosion Resistance: Due to its high purity, Grade 1100 offers outstanding resistance to corrosion, particularly in marine and industrial environments, making it ideal for outdoor applications.
- Good Electrical and Thermal Conductivity: 1100 aluminum offers excellent electrical and thermal conductivity, making it ideal for use in electrical components and heat exchangers.
- Non-Heat Treatable: Unlike many other aluminum alloys, Grade 1100 cannot be heat treated to improve its mechanical properties. It relies on its purity and the ability to be cold worked to improve its strength.
Chemical Composition of Aluminium 1100
- Aluminum (Al): 99% (min)
- Copper (Cu): 0.05 – 0.20%
- Iron (Fe): 0.70% (max)
- Manganese (Mn): 0.05 – 0.20%
- Magnesium (Mg): 0.05% (max)
- Silicon (Si): 0.25% (max)
- Zinc (Zn): 0.10% (max)
- Other Elements: Trace amounts
The high aluminum content in this grade allows it to retain its lightness while being highly resistant to rust and corrosion.
Mechanical Properties of Aluminium 1100
- Tensile Strength: 110-160 MPa
- Yield Strength: 70 MPa
- Elongation: 30% minimum
- Hardness: Brinell 25 – 35 HB
- Modulus of Elasticity: 70,000 MPa
While the strength of 1100 aluminum is lower than that of alloys like 2024 or 6061, its excellent corrosion resistance, ease of fabrication, and non-heat treatable properties make it suitable for many applications.
Applications of Aluminium 1100
Aluminium 1100 is commonly used in a wide variety of industries due to its impressive properties:
- Food and Beverage Industry: Aluminum 1100 is often used in the food packaging industry, particularly for making foil and containers because of its corrosion resistance and non-toxic nature.
- Electrical Components: Its excellent electrical conductivity makes it ideal for use in electrical components, including bus bars, wiring, and connectors.
- Chemical Processing: 1100 aluminum is highly resistant to a wide range of chemicals, making it suitable for manufacturing tanks, pipes, and other equipment used in chemical processing.
- Decorative and Architectural Applications: Due to its ease of fabrication and resistance to corrosion, it is often used in decorative trims, signage, and architectural facades.
- Heat Exchangers: Its high thermal conductivity makes it ideal for heat exchangers and other applications requiring efficient heat dissipation.
- Pressure Vessels: 1100 aluminum is also used in the production of low-pressure vessels where corrosion resistance is critical, but high strength is not the primary requirement.
Advantages of Aluminium 1100
- Superior Corrosion Resistance: Aluminium 1100 is resistant to corrosion in most natural environments, including marine and chemical conditions.
- Excellent Formability: It can be easily formed into various shapes using processes like rolling, bending, and stamping.
