3003 3004 3015 h12 aluminium coils disc
Aluminum, with its perfect blend of strength, lightweight properties, and versatility, remains a commonplace yet remarkable material in various industrial and commercial applications. Within this vast ocean of aluminum alloys, the 3000 series – specifically 3003, 3004, and the temper designation of H12 – stands out uniquely.
3003 and 3004 Alloys
Composition and Technical Phenomena
Aluminum alloy series 3003 is primarily composed of 98.93% aluminum, along with a small amount of manganese (1.0-1.5%), which serves to enhance its strength over pure aluminum. In comparison, 3004 contains slightly higher elements of manganese and magnesium, with about 95.7-98.6 % aluminum content. This essential distinction amplifies their respective properties and relevant applications.
Chemical Properties:
| Property | Aluminum 3003 | Aluminum 3004 |
|---|---|---|
| Aluminum (Al) | 98.93% | 95.7% - 98.6% |
| Manganese (Mn) | 1.0 - 1.5% | 1.0 - 1.5% |
| Magnesium (Mg) | <0.12% | 0.8 - 1.5% |
| Yield Strength | ASTM B209 - 55,000 psi | ASTM B209 - 41,000 psi |
As noted, both alloys are non-heat-treatable series, thus taking to cold working for enhancement in performance, pushing their hardness as noted in the tentative mechanical properties.
H12 Temper: What It Means
“H12” designates the work-hardened tempering of aluminum. This classification refers to a level of strength achieved by a combination of annealing and a light cold-working process, enabling a balance between ductility and strength. Due to the cold-working process in reaching the H12 specification, these aluminum coils and discs maintain an enhanced yield strength (Y.S.), allowing for functionality in packing and roofing, among other applications.
JSI (Published by the U.S. douruh Industry catalogues metals indicates a comparative yield strength between wrought aluminum benefits and compression properties):
- Yield Stress: Approx. 34,000 psi – increased hardness without eliminating ductility.
- Ductility: Retained to ensure accommodation during installation/manufacturing as per APS_METHOD H09_I210 standards or equivalent normalization procedures.
Distinctive Applications
The application range of 3003, 3004, and H12 aluminum revolves around their durability and cost-effectiveness practically extending into the consumer and construction domain.
1. Packaging Solutions
Both aluminum alloys gain significant traction in the packaging industry in the form of discs for caps in applications ranging from soft drinks to metal closures. Their superior plasticity supports a tight cap on glass and other surfaces while maintaining structural integrity under varied handling conditions.
2. Cooking Utensils
In the compliance-friendly culinary world, aluminum coils of the 3003 and 3004 series emerge as fundamental materials to manufacture pots, pans, and foil wraps. Their optimized thermal conductivity ensures even heat distribution during cooking and baking, reducing energy consumption.
3. Residential and Commercial Roofing Underlays
These alloys find adaptability on roofs where H12 ambiguity allows fewer probability risks of affordability or excess infrastructural weight. The inability to consolidate, air impermeability thus grants protection while lightening otherwise heavier external panels suited acoustically for modern buildings – Inline standard of flambossing relative to hexagonal corrolutions minimising cost-mass ratios is visible.
4. Automotive Applications
Car manufacturers esteeming lightweight components indexed frequently ascertain deals formed wherein discs serve to provide both aesthetic qualities to vehicle constructions while enhancing performance thanks to improved delta stability of suspended particulates interfering less dominantly on sub-products.
