Cc 1070 aluminum sheet
When considering the range of aluminum alloys, distinctions often fall between strength, machinability, corrosion resistance, or cost-effectiveness. However, CC 1070 aluminum sheet stands out from this conventional slate, as it epitomizes the characteristic of purity more than anything else. Known officially as “commercially pure aluminum,” the 1070 alloy holds aluminum content at minimum 99.7%, encapsulated in quality-controlled cast and wrought forms. Beyond simple metal classification, this unique compositional purity unlocks specialized functionalities promptly applicable across various industries.
Defining CC 1070 Aluminum Sheet: More Than Just “Pure”
The designation "CC" typically indicates "Continuous Cast" for furnace and roll type casting processes, refining the microstructure of the alloy sheet for enhanced uniformity. The term "1070" comes directly from the Aluminum Association numbering system indicating minimum aluminum content by weight percentage——in this case, 99.7%. According to ASTM B209 standards:
| Chemical Composition - CC 1070 Aluminum Sheet (ASTM B209) |
|---|
| Element |
| ------------------- |
| Weight % |
This means the negligible alloying elements mainly arise from unavoidable natural inclusions rather than purposeful additions, conferring upon 1070 aluminum:
- High electrical and thermal conductivity.
- Excellent corrosion resistance.
- Outstanding ductility and workability.
- Good surface reflectivity and aesthetic qualities.
Technological Features of CC 1070 Aluminum Sheet
Among aluminum alloys, the 1070 sheet knows how to specialize:
1. Exceptional Electrical Conductivity
With electrical conductivity reaching approximately 62–65% IACS (International Annealed Copper Standard), 1070 aluminum sheets are favored for electrical conduits, overhead conductors, and packaging for static-sensitive devices. Its purity promotes minimal electron scattering, ensuring superior current flow efficiency.
2. Supreme Wall for Corrosion Resistance
Thanks to the nearly pure aluminum matrix, the material naturally resists oxidation, forming the critical alumina (Al2O3) surface oxide layer protective against environmental corrosion — an essential asset in marine> and chemical exposure conditions.
3. Softness Brings Supreme Formability
With Brinell hardness ranging just 20-30 HB and tensile strength typically between 70-125 MPa depending on temper, the cold-rolled or annealed CC 1070 sheet bends, forms, and extrudes effortlessly. This mechanical softness allows the sheet metal to take intricate shapes such as complicated lamp reflectors or culinary aluminum foil smoothly.
4. Thermal Conduction Delivered
Thermal conductivity near 220 W/mK places 1070 sheet among favored protagonists for heat exchangers, cooling sleeves, or packaging working at elevated temperatures.
5. Distinctive Surface Finish and Anodizing Capability
CC 1070's surface can receive remarkable finishes — it's prime grade for decorative purposes, chemical etching, and detailed anodizing, yielding consistent bright surfaces for optical-grade reflectors or architectural cladding.
Common Tempers & Facilitation Standards
More than just being pure, the CC 1070 sheets are optimized through well-recognized ASTM tempers:
| Temper | Description | Typical Use |
|---|---|---|
| O | Annealed (soft, strain-free) | Excellent formability, bending, deep drawing work |
| H12 | Half-hard, strain hardened | Fairly good strength but some form recalibration |
| H14 | Fully hard, strain hardened | Highest strength with reduced ductility |
When clients seek specifications compliant to ASTM B209/B209M, attention must be given that sheet thickness ranges from about 0.2 mm to 6.0 mm dilating manufacturing scopes from ultra-thin foils to structural support-type thick sheets.
Practical Applications Recategorized By Feature Focus
Let's approach the applications not in generic groupings, but by how the intrinsic body of CC 1070 aluminum’s pure advantages solve vendor challenges in different sectors:
1. Electrical and Heavy Industry: Conductor and Heat Conductors
Designed for electrical cable jackets, capacitor foil blanks, or EMI shielding plates, the CC 1070 sheet capitalizes on high conductivity plus corrosion resistance to deliver safer energy transmission on long infrastructure installations in harsh atmospheres without alloy compromising durability.
2. Food and Pharmaceutical Packaging: Wrapping Safety into Supersolid Tint
When food packaging is concerned, inertness to contamination coupled with superb malleability allows the metal to fit diverse complex curved geometries, all retain wellness by retarding aeration or moisture diffusion in foil wraps. Pharmaceutically clean-smelling resins combine with rust immunity to safeguard sterility.
Building facades, accent panels, lamp reflectors, solar washers benefit from acknowledging . CC 1070 mirrors the super pure light magnetic from industries demanding luminous emphasis backed by otherwise affordable, highly workably materials.
4. Solar Panel Frame and Heat Sink Illumination
Ultra pure aluminum shines better under exposure stress—frame cross-sections for sea-facing systemic solar means long-term mildew prevention across temper imperatives achieved specifically due to initally clean-pureset metals composed.
