4104 Aluminum Foil Aluminum Welding Sheet Aluminum Welding Strip Special Aluminum Foil for Automotive Radiators

Composition and Properties

The main components of 4104 aluminum brazing sheet include aluminum, zinc, and magnesium, offering high strength, wear resistance, and corrosion resistance. These characteristics make it widely used in ship components, automotive parts, and building structures.

Welding Process and Material Properties

       Welding Process: Tungsten Inert Gas (TIG) welding or oxy-acetylene welding is recommended. Preheating (350-500°C) and slow cooling after welding are required to reduce residual stress. Excellent weldability.

       Material Properties: 4104 aluminum brazing sheet is available in annealed (O temper) or half-hard (H14) conditions to meet different strength requirements. Homogenization annealing can be performed at 510-520°C for 4-6 hours, followed by air cooling to eliminate composition segregation. Rapid annealing can be done at 350-410°C for 30-120 minutes to improve processing plasticity.
