copper aluminum flux cored wires

Hook:
Facing the challenge of joining or repairing mismatched thin-gauge metals like copper to aluminum, or stainless steel to iron? Traditional methods often struggle with differing melting points, poor wetting, and excessive heat that can damage delicate components.
Solution & Features:
Our copper aluminum flux cored wires presents a practical approach for such multi-metal tasks. The core flux is designed to promote improved wetting and flow at lower application temperatures (approximately 320°C), creating joints that exhibit good sealing properties and mechanical resilience for many repair and light fabrication needs. Its formulation is particularly suited for thin-section and small-component work across a range of metals including copper, aluminum, iron, and stainless steel, enabling dissimilar metal combinations like Cu-Al, Cu-Fe, and Al-Fe.
Product Scope & Availability:
Available in 1.6mm and 2.0mm diameters with 1 kg spools as standard. We also produce straight rod formats and support custom packaging solutions via contractual agreement to align with specific project workflows.
Typical Applications & User Guidance:
Copper aluminum flux cored wires are engineered for repair and light fabrication on thinner materials. Example scenarios where it finds utility include:
Sealing leaks in aluminum boat fuel tanks or cooling system components.
Crack repair on aluminum engine blocks, transmission housings, or oil pans.
Patching holes in aluminum radiator fins or heat exchangers.
Build-up welding for worn aluminum fittings.
Joining aluminum wire to copper terminals in transformers or copper-aluminum busbars.
Repairing aluminum-to-copper tube joints in refrigeration condensers/evaporators.
Work on heat sinks and motor housings.
For optimal results, it is recommended for thin-gauge materials and is generally not specified for very hard, thick castings or for primary load-bearing structural applications in heavy industry.
