Aluminum Coil 1050 1060 1070 1100
Aluminum coils find ubiquitous applications in modern industries, characterized by their versatility, lightweight nature, and corrosion resistance. Among aluminum alloys, the 1xxx series stands out for its high purity and excellent electrical and thermal conductivity. Specifically, Aluminum coils in grades 1050, 1060, 1070, and 1100 represent subtle variations in purity and mechanical properties that dictate their specialized uses.
the Chemical Composition and Its Impact
The numerical designation of these alloys stems from the Aluminum Association's system where series 1xxx indicates at least 99% aluminum content. Among the four alloys:
- 1050: 99.5% minimum Al
- 1060: 99.6% minimum Al
- 1070: 99.7% minimum Al
- 1100: 99.0% minimum Al (but with alloying additions increasing it beyond pure Al diversity)
| Alloy | Aluminum (Al) % Min. | Silicon (Si)% Max | Iron (Fe)% Max | Copper (Cu)% Max | Manganese (Mn)% Max | Others % (Max) |
|---|---|---|---|---|---|---|
| 1050 | 99.5 | 0.25 | 0.40 | 0.05 | 0.03 | 0.15 |
| 1060 | 99.6 | 0.25 | 0.35 | 0.05 | 0.03 | 0.15 |
| 1070 | 99.7 | 0.25 | 0.30 | 0.05 | 0.03 | 0.15 |
| 1100 | 99.0 | 0.95 | 0.95 | 0.20 | 0.05 | 0.05 |
The climbing purity from 1050 through 1070 efficiently boosts conductivity and corrosion resistance, making 1070 particularly valuable in sophisticated electrical components. 1100 stands apart slightly, incorporating controlled traces of copper, manganese, and iron to enhance strength—with a trade-off on conductivity—rendering it a popular choice when higher mechanical integrity is essential.
Tempering and Mechanical Properties: Tailoring the Coil’s Endurance
Aluminum coils do not achieve their utility and formability solely based on chemical makeup. The temper designation—through annealing or work hardening—affects crucial mechanical parameters:
| Alloy | Temper | Tensile Strength (MPa) | Yield Strength (MPa) | Elongation (%) | Conductivity (% IACS) |
|---|---|---|---|---|---|
| 1050 | H14 | 90 | 35 | 2-4 | 61-63 |
| 1060 | O (annealed) | 45 | 15 | 35-40 | 61-62 |
| 1070 | H12 | 100 | 40 | 15 | 63 |
| 1100 | H24 | 115 | 85 | 5-10 | 34-38 |
- O Temper (Annealed): Soft and highly ductile coil, ideal for deep drawing and easy forming.
- H Temper: Strain-hardened types with varying degrees of hardness and ductility balancing strength and formability.
Application-driven temper selection ensures these coils meet operational expectations from flexibility in tight fabrications to Sturdiness in structural panels.
Distinctive Features & Skilled Applications Highlight
1050 — The Workhorse of Purity and Morphees Strategies
Boasting high aluminum content coupled with good formability, Alloy 1050 is engineered for applications emphasizing pliability over raw strength. Its uniform grain structure responds well under rolling and pressing, making it picturesque for food packaging foils, reflective mirror bases, and signal reflectors. Because of broad availability, its price-to-performance ratio maintains excellent appeal in mass manufacturing.
1060 — Leading Conductor in Coil Dressings
1060 shifts its standout feature to marginally better electrical conductivity, favored in coil winding for transformers or capacitors. Its refined balance of softness and conductivity also escorts innovation in decorative facades and intricate architectural laminates surviving through weather's wrath — further carved out by O temper’s softness.
1070 — Specialist Conductor with Precision Edge
At 99.7% aluminum, the super-attractive specification means 1070 coils excellently encode purposes where top heritage-grade feeders must carry current without compromise: busbars, capacitors, and AC contacts. Enterprises promoting sustainable electronics expand usage in this alloy, marrying efflorescent properties with fine machinability.
1100 — Multiuse Alloy Blending Coy Resistances and Strength
Downgrading slightly on purity but upping trace elements account for 1100's demonstrated robustness; an adept hybrid retaining formability post-strain unhindered by service indentations. This more 'hinted' alloy tackles roofing, siding foils, and mural facades featuring increased requirements for dents resistance without sacrificing aluminum's hallmark rust immunity.
Momentum in Industrial Solutions Driven by Subtle Alloy Choices
these 1xxx series distinctions verifies one does not sift blindly through “pure aluminum coils.” Subtle modifications impact a spectrum from electrical efficiency and surface finishes to drawing capacity and strength trade-offs.
- For electrical engineers working on bulk conductors, 1060 and 1070 outclass mildly used counterparts,
- Designers and architects model with ambience-hardened 1100 offering both lightweight panels and enduring reliability,
- And every OEM acutely recognizes balancing price, weight, formability, corrosion endurance amid merch production makes 1050 a pragmatic star within general metal domains.
The four alloys implement microcosms of developing applications yet carry legacy and future weight alike—from fabricating clean electrical conductive circuits, vibrant neon facades, renewable energy components, to discreet household goods shaping modern living.
