1050 / H14 Color Coated Aluminum Coil: Specifications & Applications

In the hierarchy of non-ferrous materials, the 1050 color coated aluminum coil represents the pinnacle of purity and processability. As a commercially pure alloy ( ≥99.5% Al), it offers unrivaled electrical and thermal conductivity, while the H14 temper provides the "sweet spot" of mechanical strength required for complex fabrication. In 2026, this material has become indispensable for projects requiring high corrosion resistance and superior surface aesthetics.        

Technical Specifications

The Metallurgy of Purity

The 1050 alloy is distinguished by its lack of significant alloying elements, which allows it to maintain the natural advantages of aluminum.

Chemical Composition & Physical Constants

The "1050" designation signifies a minimum aluminum content of 99.5%. The remaining balance consists primarily of Iron (0.40%) and Silicon (0.25%), which provide a slight boost to strength without compromising conductivity.

Density:2.705cm³ (ideal for lightweighting).

Melting Point: Approximately $646°C.

Thermal Conductivity: 230 W/m·K, making it a leader in heat dissipation roles.

Mechanical Properties of the H14 Temper

The H14 color coated aluminum coil is strain-hardened to a "half-hard" state. This temper ensures the material is rigid enough to maintain its shape but ductile enough for 90-degree bending and roll-forming.

Dingang’s Professional Architecture: Coating & Precision                   

At Dingang Metal, the production of 1050 H14 coils integrates high-speed continuous coating with precision metallurgy to ensure a defect-free finish.

Coating Chemistry for High-Purity Substrates

Because 1050 aluminum is highly ductile, the coating must be flexible enough to withstand deformation without cracking (T-bend performance).

PE (Polyester)

Best for indoor signage, appliances, and general decoration where cost-effectiveness and color vibrancy are prioritized.

PVDF (Fluorocarbon)

Recommended for outdoor HVAC cladding and industrial environments where UV resistance and chemical stability are critical.

Surface Uniformity and Tension Leveling

To ensure the H14 color coated aluminum coil performs perfectly in automated production lines, we apply Tension Leveling. This process removes internal stresses from the coil, ensuring absolute flatness—a critical requirement for electronic enclosures and large-scale architectural panels.

Diverse Applications

Where Performance Meets Purity

The combination of high conductivity and moderate strength makes 1050 H14 a versatile workhorse across multiple sectors.

HVAC and Industrial Insulation

Due to its 99.5% purity, the 1050 alloy is highly resistant to atmospheric corrosion.

Pipe Jacketing

Often used in 0.5mm- 1.0mm thickness for cladding thermal insulation pipes in factories and high-rise basements.

Heat Exchangers

Its high thermal conductivity (230W/m·K) makes it the preferred base for radiator fins and cooling units.

Electronics and Lighting Reflectors

Enclosures

Used for circuit board housings and micro-processor cabinets where "soft" shielding and easy stamping are required.

Lamp Reflectors

When coated with high-gloss or mirror finishes, the 1050 base provides the highest reflectivity of any common aluminum grade.

Construction and Signage

Traffic Signage

The H14 temper provides the necessary stiffness for road signs while remaining easy to paint or apply reflective films.

Roofing and Gutters

In coastal or high-humidity regions, 1050 is often chosen over 3000-series alloys specifically for its superior natural oxide layer protection.

Conclusion

The 1050 color coated aluminum coil is the ideal solution for industries where purity is not just a preference, but a requirement. By utilizing the H14 temper, Dingang Metal delivers a product that balances the workability of pure aluminum with the structural reliability needed for 2026’s most demanding architectural and industrial projects.
