J73A UP® is a durable, 20 µm pre-anodized aluminum solution modeled after Novelis J57S UP®, offering strong corrosion and weather resistance for architectural uses like façade cladding and roofing. The anodized coil features high surface hardness, consistent finish, and lasting color thanks to outstanding UV resilience.
The industrial coil anodizing process gives Novelis J73A UP® reliable quality and cost-effectiveness. It suits various functional and decorative needs across building, engineering, electronics, and chemical industries.
Novelis J73A UP® delivers impressive hardness and weather resistance, earning A1 (DIN 4102) and non-flammable ratings. Its uniform anodizing layer blocks edge defects from batch processes, making it ideal for structures over 20 meters tall, aluminum façade cladding, and roofing.
Designed for accentuating contrast or blending with surroundings, Novelis J73A UP® supports versatile facade cladding design.
Resistant to corrosion between pH 5.5–8 and maintains integrity even when bent. Its anodic layer exceeds international standards and offers superior sealing against corrosion; no peeling or filiform corrosion occurs due to its firm bond with the base material.
Continuous-anodized quality from a single source ensures a long service life for this aluminum coil stock. Many buildings with continuous-anodized facades – some built 20 years ago – have been examined by independent engineers to determine the quality of the anodic layer. Their results:
