Product Name: Nocolok Material Aluminum Cladding Coil Sheet 4343 3003 4343

Nocolok Material Aluminum Cladding Coil Sheet is a specialized material designed for use in the automotive and aerospace industries. This innovative material incorporates a layer of pure aluminum between two layers of an aluminum alloy (generally 3003 or 6061) to create strong, lightweight, and corrosion-resistant cladding. The Nocolok bonding process uses a fluxless brazing technology that eliminates the need for separate filler metals, resulting in a cost-effective and environmentally-friendly solution with fewer welding defects. The resulting product offers superior thermal conductivity and high-temperature resistance, making it ideal for use in automotive radiators, intercoolers, and heat exchangers in the aerospace industry.
