Aluminium coil 1050 1060 h14
Aluminium Coil 1050 1060 H14: A Practical Guide from the Production Floor to Your Application
When people search for aluminium coil, they often see codes like 1050, 1060, and H14, then wonder what these numbers and letters really mean in practice. From a factory perspective, these are not just labels. They describe how the material behaves on your machine, how it looks after forming, how it resists corrosion, and how consistently it will perform in mass production.
the Alloy Codes: 1050 vs 1060
In the 1xxx series, aluminium coil is almost pure aluminium with very low alloy additions.
- 1050 aluminium: nominally at least 99.5 percent pure aluminium
- 1060 aluminium: nominally at least 99.6 percent pure aluminium
The tiny difference in purity might look trivial, but it shapes performance in subtle ways. Higher purity tends to give slightly better electrical conductivity and corrosion resistance, while strength remains relatively low compared with 3xxx, 5xxx or 6xxx series alloys.
For customers, the choice between 1050 and 1060 typically depends on:
- Required conductivity: busbars, electrical strips, transformer windings lean toward 1060
- Cost and availability: 1050 is widely available and very cost effective
- Forming requirements: both are very soft by nature, so their temper makes more difference than the slight purity change
The Meaning of H14: Where Strength Meets Formability
Temper is where the alloy becomes a usable product instead of just a metal. H14 is a work hardened, half hard temper. In simple terms, the material is cold rolled to increase its strength to a medium level, then controlled to avoid becoming too hard or brittle.
From a process viewpoint, H14 offers a balance that many manufacturers like:
- Stronger than O temper (soft annealed) and H12
- Still sufficiently ductile for bending, shallow drawing and stamping
- Stable surface and consistent mechanical performance in continuous production
In actual fabrication, you will notice that 1050 1060 H14 coils:
- Resist denting and handling damage better than fully soft coils
- Hold their shape more accurately after bending
- Do not crack easily during normal radius bends when bending guidelines are followed
Typical Parameters and Mechanical Properties
While exact values depend on thickness and standards, the following ranges are typical for 1050 1060 H14 coils produced to major international norms such as ASTM B209, EN 485, or GB/T standards.
Typical thickness range
- 0.2 mm to 6.0 mm for coil products
Typical width range
- 20 mm to 2000 mm, depending on mill capability
Mechanical properties for 1050 H14 (reference values)
- Tensile strength: about 95 to 125 MPa
- Yield strength: about 60 to 100 MPa
- Elongation (L0 = 50 mm): about 4 to 12 percent, depending on thickness
Mechanical properties for 1060 H14 (reference values)
- Tensile strength: about 95 to 120 MPa
- Yield strength: about 55 to 95 MPa
- Elongation: roughly similar to 1050 H14
These values give a clear picture. The material is not high strength but rather targeted for excellent workability, easy forming, and reliable performance in non load bearing or lightly loaded components.
Chemical Composition: Why Purity Matters
Below is a typical chemical composition table for 1050 and 1060 aluminium according to common standards. Actual values may vary slightly by standard and producer, but the trend remains the same: very high aluminium content, extremely low alloying elements.
Chemical composition of 1050 aluminium, percent by weight
- Aluminium (Al): ≥ 99.5
- Silicon (Si): ≤ 0.25
- Iron (Fe): ≤ 0.40
- Copper (Cu): ≤ 0.05
- Manganese (Mn): ≤ 0.05
- Magnesium (Mg): ≤ 0.05
- Zinc (Zn): ≤ 0.07
- Titanium (Ti): ≤ 0.03
- Others (each): ≤ 0.03
- Others (total): ≤ 0.10
Chemical composition of 1060 aluminium, percent by weight
- Aluminium (Al): ≥ 99.6
- Silicon (Si): ≤ 0.25
- Iron (Fe): ≤ 0.35
- Copper (Cu): ≤ 0.05
- Manganese (Mn): ≤ 0.03
- Magnesium (Mg): ≤ 0.03
- Zinc (Zn): ≤ 0.05
- Titanium (Ti): ≤ 0.03
- Others (each): ≤ 0.03
- Others (total): ≤ 0.10
From a user viewpoint, high aluminium content gives:
- Excellent electrical and thermal conductivity
- Natural corrosion resistance due to a stable oxide layer
- Clean metallic appearance and easy surface treatment such as anodizing or coating
Implementation Standards and Quality Control
In global trade and automotive, HVAC, or electrical supply chains, aluminium 1050 1060 H14 coils are typically ordered and inspected against recognized standards. Common references include:
- ASTM B209 for flat rolled aluminium in North America
- EN 485 and EN 573 in Europe
- GB/T 3190 and GB/T 3880 in China
When specifying material, buyers usually define:
- Alloy and temper: 1050 H14 or 1060 H14
- Thickness tolerance: depending on application, often down to ±0.02 to ±0.05 mm for thin gauges
- Width tolerance and edge condition: mill edge or slit edge
- Surface quality: plain mill finish, embossed, or coated; restrictions on scratches, roll marks, and oil stains
- Coil parameters: inner and outer diameter, maximum coil weight, and core type
From a practical sourcing standpoint, choosing a supplier that can repeatedly hit narrow tolerances is often more important than a theoretical difference between 1050 and 1060. Stable rolling, consistent temper, and clean surface finish directly affect your production efficiency.
Functional Strengths of 1050 1060 H14 Coil
Looking at the alloy as a tool in your workshop, several functional strengths stand out.
Formability and bending behavior
The half hard H14 temper lets you form brackets, ducts, light covers, panels, and reflectors without excessive springback or cracking, as long as you follow reasonable bend radii.
Corrosion resistance
In neutral and mildly corrosive environments, 1xxx series aluminium resists rust without needing heavy protective systems. For indoor HVAC ducts, interior panels, and general enclosure parts, plain mill finish or lightly coated surfaces are sufficient.
Conductivity
These grades offer high electrical and thermal conductivity, making them suitable for busbars, shielding, transformer strips, and heat transfer components like fin stock and evaporator plates.
Surface adaptability
Because the aluminium is so pure, it responds well to:
- Anodizing for decorative or protective finishes
- Painting and powder coating for color and branding
- Embossing for anti slip or decorative textures
Where 1050 1060 H14 Really Work in the Field
Instead of listing applications by category only, it is useful to match coil behavior with actual workshop processes.
In HVAC and ventilation fabrication
Coils in H14 temper run smoothly on decoiling, roll forming, and bending lines for ducts, air distribution components, plenums, and casings. The material does not crack on standard bends, and its moderate stiffness helps ducts keep their shape after installation.
In lighting and interior systems
Reflector panels, lamp housings, decorative trims, and ceiling panels benefit from the clean surface and easy forming of 1050 1060 H14. The material can be bright anodized or mirror finished to improve reflection in lighting systems.
In electrical and thermal uses
For parts where conductivity drives performance more than strength, such as busbars, cable trays, shielding plates, and heat sinks in non structural roles, these alloys excel. H14 temper prevents parts from being too soft while still allowing punching, notching, and forming.
In packaging and consumer goods
While ultra thin gauge foil uses more specialized tempering, thicker gauges of 1050 1060 H14 are common in lids, caps, paneling for instruments and appliances, and general formed covers where corrosion resistance and clean appearance are key.
Choosing Between 1050 and 1060 in Practice
From an engineering angle, the decision typically follows this logic:
Choose 1050 H14 when you need cost effective, easily formable aluminium with standard conductivity and broad availability. Suitable for ducts, panels, covers, and general fabrication.
Choose 1060 H14 when your design emphasizes electrical or thermal conductivity and extremely clean, pure aluminium. Often used in electrical, electronic, and heat transfer components.
Both share similar processing routes, cutting behaviors, and surface treatment options, so your existing production lines usually handle either grade without modification.
Aluminium coil 1050 1060 H14 brings together high purity aluminium with a practical, half hard temper. The result is a coil that:
- Is easy to form yet not too soft
- Offers excellent corrosion resistance and conductivity
- Meets widely recognized standards like ASTM, EN, and GB
- Adapts well to bending, stamping, roll forming, and surface finishing
For buyers and engineers, thinking about this material as a balanced solution between softness and productivity, between purity and cost, helps clarify when it makes sense. When you need reliable forming, clean surfaces, and high conductivity without the complexity of heavily alloyed grades, 1050 1060 H14 aluminium coil remains one of the most straightforward and efficient choices.
