AlcoTec R4043 Altigweld Aluminum Welding Rod

Crafted for exceptional TIG (GTAW) welding performance. With a silicon content of 4.5-6.0%, R4043 enhances fluidity and reduces hot cracking risks, producing smooth, bright, and clean welds.

This non-heat-treatable rod is ideal for joining 6XXX series aluminum alloys and dissimilar aluminum alloys. The added silicon improves the weld’s mechanical properties, making it less sensitive to weld cracking and more forgiving in various welding conditions.

Applications of R4043 Altigweld Aluminum Welding Rod

Automotive Repairs and Manufacturing: R4043 is widely used for welding automotive components, such as cylinder heads and fuel tanks. Its ability to create leak-proof, corrosion-resistant welds makes it perfect for critical parts that require durability and reliability.
Aerospace Fabrication: This rod is excellent for aerospace applications, including welding fuselage panels, wing structures, and fuel tanks. It provides high strength and resistance to thermal expansion, thus essential for components exposed to fluctuating temperatures and high-stress conditions.
Heat Exchangers and Radiators: The high silicon content ensures excellent thermal conductivity and corrosion resistance, making R4043 ideal for welding heat exchangers, radiators, and other cooling components. It provides consistent weld quality, even in demanding environments.
General Aluminum Fabrication: R4043 is suitable for general aluminum fabrication, including structural components, frames, and ornamental work. Its excellent fluidity and reduced shrinkage allow for precise, high-quality welds with minimal post-weld finishing.
Marine Applications: Due to its corrosion resistance, R4043 is perfect for welding aluminum components used in marine environments, such as boat hulls and deck structures. Consequently, it ensures long-lasting performance in saltwater and harsh weather conditions.
Architectural Projects: This welding rod is perfect for architectural applications that focuses on aesthetics and strength. It ensures smooth, bright welds that enhance the visual appeal and durability of aluminum structures.

AlcoTec R4043 Altigweld Aluminum Welding Rod meets key industry standards, including ANSI/AWS A5.10 (ER & R) and AMS 4190, indeed ensuring compliance with rigorous quality requirements. It delivers consistent welds, minimal spatter, and superior results in every application.
