1100 Aluminum sheet Coil
Aluminum has long since claimed its territory as one of the essential materials for a multitude of industrial applications. Among the myriad grades available, 1100 aluminum sheet coil stands out, owing its high corrosion resistance, formability, and thermal conductivity to its elemental structure.
1100 Aluminum Alloy
Aluminum alloy 1100 is characterized primarily by its purity—comprising 99% or more aluminum. This non-heat-treatable alloy belongs to the Aluminum Association’s 1000 series and boasts a number of traits suitable for a variety of usages. Unlike other aluminum grades that often blend materials for enhanced properties, 1100 derives its performance from its basic composition, making it unique.
Chemical Composition
The typical chemical composition of 1100 aluminum alloy includes:
| Element | Percentage |
|---|---|
| Aluminum (Al) | 99.00% min |
| Copper (Cu) | 0.05–0.20% |
| Iron (Fe) | 0.0–0.70% |
| Manganese (Mn) | 0.0–0.05% |
| Magnesium (Mg) | 0.0–0.10% |
| Silicon (Si) | 0.0–0.60% |
| Titanium (Ti) | 0.0–0.05% |
| Zinc (Zn) | 0.0–0.10% |
With minimal alloying agents, 1100 emphasizes excellent ductility and malleability while achieving notable resistance against corrosion and oxidation.
Outstanding Characteristics
One of the standout features of 1100 aluminum sheet coil is its workability. This is partly attributed to its very high elongation rate, which is normally over 15% in annealed sheets. This ductility allows for deeper draws and complex shapes, making it perfect for forming operations.
Further, the thermal and electrical conductivity of 1100 aluminum is remarkable, making it useful in applications where heat management is crucial. Its conductivity level reaches approximately 61% of the International Annealed Copper Standard (IACS).
In terms of corrosion resistance, 1100 aluminum sheet coil resists moisture, atmospheric elements, and corrosion from chemicals, thus extending durability and reducing the need for expensive coatings or cladding.
Applications of 1100 Aluminum Sheet Coil
The versatility of 1100 aluminum sheet coil translates to a wide variety of applications across numerous fields:
1. Food and Pharmaceutical Packaging
Due to its non-toxic nature and corrosion resistance, aluminum foil and sheet from the 1100 series is predominantly used in the food and pharmaceutical industries. Outfitting cans, covers, and seals, the expansive use stems from 1100’s capability to protect from light, moisture, and bacteria, extending product shelf life.
2. Decorative applications
In arts, montages, and architectural elements, 1100 aluminum sheet’s exceptional smoothness can be utilized for esthetic enhancers such as fascias, interior and exterior trims. Non-insulated panels produced from this alloy combine strength and elegance, framing architectural features delicately without compromising structural tenacity.
3. Heat Exchangers and HVAC systems
For manufacturers in sewing systems or painting booths that demand effective heat dissipation capabilities, whole 1100 series coil convection heaters and containers emerged due to its high thermal conductivity and efficiency.
4. Transportation
With a focus on lightweight components, 1100 aluminum coils figure into automotive and aerospace industries, improving fuel efficiency without heavily detracting prices.
Fabrication Techniques
To maximize performance, handling tools tailor operations such as shearing and punching per the 1100 alloy shelving guide standards to engagement points that prioritize tempering, yielding the highest impact with operational efficiency:
- Cold working: For reducing thickness while boosting hardness.
- Annealing: For optimizing ductility where bending occurs.
Provided Tempering Standard:
For aluminum 1100, common tempering designations may involve:
- H14: Striplith Cold Rolled (Strength exceeds (0.3–0.4 tensile strength) UTS.)
- H16: Mechanically worked coil with a further higher tensile compared with H14 internment gradually strong codes allowable for random formability compatibility intefragritial conflicts lazily specifying personalizations.
