3003 H14 Aluminum Coil

3003 H14 aluminum coil is a widely used 3-series Al-Mn anti-rust alloy coil, commonly applied in both industrial and everyday processing fields.

The "H14" temper designation indicates that it is produced using a semi-cold work hardening process, achieving an excellent balance between strength and ductility — it is stronger and more durable than pure aluminum, while still maintaining good formability to meet various forming and processing requirements.

3003-H14 is a non-heat-treatable wrought aluminum alloy, featuring excellent formability, moderate strength, and high corrosion resistance as its core advantages. Its strength is about 20% higher than that of 1100 series aluminum alloys, offering well-balanced overall performance. It is an ideal material for roofing and wall trims, kitchen equipment, heat exchangers, general sheet metal parts, and battery enclosures.

3003 H14 Aluminum Coil Purchasing and Usage Recommendations

When selecting and using 3003 H14 aluminum coil, we recommend making targeted choices based on specific application scenarios to ensure that material performance matches usage requirements.

Regarding specification selection, different applications have varying thickness requirements. For example, when used for battery enclosures, a thickness range of 0.8–2.0mm is generally recommended to balance strength and formability; whereas for water cooling plates and other heat-dissipating structures, a thickness of 1.0–3.0mm is more suitable to meet structural stability and thermal conductivity needs.

For surface treatment, it should be matched appropriately according to the usage environment. For outdoor or complex environments, a coated finish is recommended to enhance corrosion resistance and service life; for food contact applications, anodizing that meets food-grade standards is suggested to ensure safety and hygiene compliance.

During processing, 3003 H14 is in a semi-hard state with excellent cold working performance, suitable for stamping, bending, and similar operations. However, note that this alloy is not heat-treatable, and high-temperature treatments should be avoided to prevent compromising its original properties.

For storage, we recommend keeping the environment dry and ventilated, avoiding contact with acidic or alkaline substances. During handling and stacking, take protective measures to prevent surface scratches or dents, ensuring the material's appearance quality and subsequent processing performance.
