AlcoTec R4047 Altigweld Aluminum Welding Rod

AlcoTec R4047 (R 4047) Altigweld Aluminum Welding Rod is specifically designed for high-quality TIG (GTAW) welding of aluminum. With a high silicon content of 11-13%, R4047 provides improved fluidity and reduces shrinkage. The end result is smooth, bright, and clean welds.

This non-heat-treatable rod is ideal for applications involving high-silicon aluminum alloys, in addition to applications favouring low melting points and narrow freezing range. The increased silicon content also enhances the weld’s mechanical properties and provides a reduced risk of hot cracking, ensuring consistent weld quality.

Applications of R4047 Altigweld Aluminum Welding Rod

Automotive Manufacturing: R4047 is common in the automotive industry for welding aluminum parts like radiators, fuel tanks, and transmission cases. Its ability to create smooth, leak-proof welds makes it perfect for components requiring structural integrity and durability.
Aerospace Components: This rod is excellent for welding aluminum aerospace components, such as fuselage panels, fuel tanks, and heat exchangers. It offers high strength and resistance to thermal expansion, essential for parts exposed to fluctuating temperatures.
Heat Exchangers: The high silicon content of R4047 ensures efficient thermal conductivity and corrosion resistance, making it ideal for welding heat exchangers and similar equipment. The rod provides consistent weld quality even in demanding environments.
Brazing Applications: R4047’s low melting point and narrow freezing range make it suitable for brazing aluminum alloys. It offers precise control for joining thin or dissimilar metals, providing strong, clean joints.
Architectural Structures: This welding rod is perfect for architectural applications where both aesthetics and strength are necessary. It ensures smooth, bright welds that are visually appealing and durable.
General Fabrication: R4047 is used for general aluminum fabrication, including ornamental work, aluminum frames, and structural components. Its excellent fluidity allows for precise, high-quality welds with minimal post-weld finishing.

AlcoTec R4047 Altigweld Aluminum Welding Rod meets key industry standards, including ANSI/AWS A5.10 (ER & R) and AMS 4185, ensuring compliance with rigorous quality requirements. It is suitable for applications requiring sustained elevated temperatures and offers excellent corrosion resistance and weldability.
