CC DC alloy 1050 1060 aluminium circle for cookware lighting
Aluminum Alloys: 1050 vs. 1060
Both the 1050 and 1060 grades of aluminum belong to the 1000 series, known for its exceptional corrosion resistance, excellent electrical conductivity, and superior malleability. While they offer similar attributes, a few distinctions set them apart.
Alloy 1050
Composition: Aluminum content ≥ 99.5%
Mechanical Properties: Good ductility and moderate strength.
Applications: Commonly used in cookware, particularly frying pans and non-stick pans, due to excellent thermal conductivity.
Alloy 1060
Composition: Aluminum content ≥ 99.6%
Mechanical Properties: Superior strength compared to 1050.
Applications: Used widely in lighting fixtures and diffusers, thanks to its capability to channel and reflect light efficiently.
Characteristics of CC and DC Process
The method of manufacturing aluminum circles can significantly affect their properties:
Continuous Casting (CC):
Produces more uniform thickness and enhanced surface quality.
This is particularly beneficial for cookware since consistency is crucial for heat distribution.
Direct Chill (DC):
Offers better mechanical properties compared to CC-treated alloys.
The resulting grain structure ensures tighter dimensions and enhanced strength, ideal for technical applications like lighting where durability matters.
Implementation Standards and Tempering Conditions
Aluminum circles for cookware and lighting need to meet specific international standards to ensure consistency and reliability during usage. Below are some parameters to give a clearer insight:
| Parameter | 1050 Alloy | 1060 Alloy |
|---|---|---|
| Aluminum Content | ≥ 99.5% | ≥ 99.6% |
| Yield Strength | 90-120 MPa | 95-160 MPa |
| Elongation | 18% (thickness 6mm)0 | 17% (thickness 6mm) |
| OSHA Regulations | Compliance | Compliance |
| Surface Finish | Mill finish | Anodized / Polished |
Alloy Tempering:Choosing the right temper – a designated process treating the metal – will also significantly influence the essential properties:
- H14 (Strain-Hardened): This application offers a balance between formability and potential strength.
- O (Annealed): Typically used for conditions requiring high ductility and corrosion resistance.
Standard guidelines like ASTM B221 (Standard Specification for Aluminum and Aluminum-Alloy Extruded Bars, Rods, Wire, Profiles, and Tubes) and ASTM B209 (Standard Specification for Aluminum and Aluminum-Alloy Sheets and Plates) buffer the reliability toward compliance for production of aluminum circles.
Chemical Properties
Consideration for chemical properties provides a holistic view of the functionality of aluminum cookware and lighting products:
| Chemical Property | Aluminum Content | Iron (Fe) | Copper (Cu) | Zinc (Zn) | Silicon (Si) |
|---|---|---|---|---|---|
| 1050 | Exceeds 99.50% | Below 0.4% | Below 0.05% | Below 0.1% | Below 0.25% |
| 1060 | Excels 99.60% | Below 0.4% | Below 0.03% | Below 0.1% | Below 0.25% |
Note: All values may vary based on specific production batch protocols; consultation with the supplier for definitive figures is encouraged.
