3003-H14 Aluminum Alloy for Battery Enclosure Material

Mingtai Aluminum is a leading producer of 3003-H14 aluminum alloy for lithium-ion battery enclosures. With advanced rolling and annealing technology, Mingtai produces 3003-H14 aluminum coil with superior properties perfectly suited for battery shell applications:

•High Corrosion Resistance: 3003-H14 forms a protective oxide film that protects against electrolyte corrosion and environmental weathering. Its density and non-porous surface prevent moisture ingress.

•Lightweight: 3003-H14 aluminum alloy is approximately 1/3 the weight of steel, allowing lighter battery packs and enclosures for greater energy efficiency.
•Good Formability: 3003-H14 aluminum sheet can be readily stamped, drawn and folded into box sections for battery shells. It facilitates high-volume production and lower costs.
•Strong and Durable: With moderate strength, 3003-H14 aluminum enclosures provide structural protection for battery cells over a long service life.
•Safety: Unlike steel, 3003-H14 aluminum sheet will not spark upon impact and is non-magnetic. This improves safety where sparking risks explosion.
•Recyclable: 3003-H14 is highly recyclable, supporting a sustainable material cycle.
Mingtai Aluminum is an ideal supplier of 3003-H14 aluminum sheet coil for battery manufacturers and pack assemblers. With 20+ years serving the new energy sector, Mingtai understands the technical requirements and high standards for quality and responsibly sourced materials.
