Key Advantages & Novelis USP

Natural gray color formation (no dyes added): the characteristic tone forms naturally due to the special surface and alloy.

Durable coil anodized surface & protective film: firm bond with the metal surface helps prevent corrosion, chipping and peeling; 80 µm protective film applied on the anodized side.

Resilient in service: weather resistant and UV resistant; corrosion resistant in neutral pH environments; retains color in harsh conditions.

Fire safety: non‑combustible (DIN 4102); Rating class A1 per 96/603/EG.

Sustainable: 100% recyclable; supports low‑maintenance, long‑life envelopes.

Design & processing flexibility: lightweight yet strong; easily formed for modern façade and interior geometries.

At Novelis, we work closely with our customers to support individual requirements for innovative and custom solutions.
