Matériaux des Langhe 3003 Feuille d'aluminium, an AL–Mn-series alloy, offers superior anti-rust performance, approximately 10 % higher strength than 1100-series foil, excellente formabilité, weldability and corrosion resistance. Produced in thicknesses from 0.006 mm to 0.2 mm and widths up to 1 700 mm, it serves industries from electronics and packaging to aerospace and construction. Our factory-direct supply ensures competitive pricing, flexible customization, stable quality, and timely global delivery.

1. What Is 3003 Feuille d'aluminium?

3003 Aluminum Foil belongs to the aluminum–manganese (Al–Mn) alloy family. By adding about 1–1.5 % Mn to pure aluminum, the alloy achieves:

Enhanced strength (≈10 % higher than 1100-series)
Superior anti-rust (oxidation) properties
Good formability, weldability, and corrosion resistance

Unlike pure-Al foils (par exemple. 1100-série), 3003 strikes a balance between strength and workability, making it a versatile “all-purpose” foil.

4. Production & Contrôle de qualité

Langhe Materials operates semi-continuous casting and rolling lines, with advanced Andritz foil mills imported to ensure precise gauge control and minimal defects. Each batch undergoes:

In-process thickness & width monitoring
Surface defect inspection (to prevent pinholes, “bubbles”)
Chemical analysis (to confirm alloy ratios)
Tensile & elongation tests

We hold ISO 9001 certification and comply with GB, ASTM, EN and GOST standards .
