3003 H14 Aluminum Coil
3003 H14 aluminum coil is a commonly used aluminum-manganese (Al-Mn) alloy coil that combines corrosion resistance, good formability, and moderate strength. It offers high cost performance and is widely used in construction, HVAC (heating, ventilation, and air conditioning), packaging, and industrial equipment.
The 3003 alloy is based on commercially pure aluminum with the addition of manganese, which increases its strength by about 20% compared with 1100 series aluminum alloys. It has excellent deep drawing, spinning, welding, and brazing capabilities, but its strength cannot be increased through heat treatment. Typical applications include cookware, decorative trim, awnings, wall panels, storage tanks, and chemical equipment.
The rolled surface finish of 3003-H14 aluminum coil complies with standards such as AMS-QQ-A-250/2, AMS 4008, and ASTM B209, ensuring reliable processing performance and corrosion resistance.
What is 3003 H14 Aluminum?
3003 H14 aluminum coil is an aluminum product made from aluminum-manganese alloy (3003) through partial strain hardening (H14 temper).
Alloy: 3003 (Al-Mn series)
Temper: H14 (strain-hardened, half-hard condition)
The H14 designation accurately describes the treatment applied to the metal after casting:
- H: Indicates that the material has been "strain hardened" (cold worked) to increase strength.
- 1: Indicates that the material has only been strain hardened (no heat treatment was performed to reduce hardness).
- 4: Indicates the hardness level. In this case, the hardness is 1/2. This is the “just right” hardness—hard enough to maintain its shape, yet soft enough to bend to a 90-degree angle without cracking.

What is the difference between 3003 and 3003 H14?
3003 is the base aluminum alloy designation, while 3003 H14 is a specific temper (half-hard condition) of the 3003 aluminum alloy. The two have the same chemical composition, but their mechanical properties and application scenarios differ significantly due to different processing methods.
