Harris AL200RC Alcor Fluxed Aluminum Alloy

The Harris AL200RC Alcor Fluxed Aluminum Alloy is a professional-grade, cadmium-free brazing filler metal engineered specifically for high-integrity repairs on aluminum components. Designed with a non-corrosive flux core, this alloy eliminates the requirement for external flux application, significantly reducing bench time and preventing contamination in sensitive systems. With a precise eutectic melting point of 824°F (440°C), Alcor provides exceptional fluidity and capillary attraction, allowing the alloy to pull into tight joint clearances of 0.003" to 0.005" without compromising the base metal. This low-temperature profile is critical when working on 1000, 3000, and 6000 series aluminum alloys, as it minimizes the risk of melting or warping the parent material. Veteran technicians rely on Harris Alcor brazing wire for permanent, leak-proof seals in heat exchangers, AC evaporators, and aluminum-to-copper transitions, ensuring RoHS and REACH compliance on every service call.

Key Benefits for the Technician:

• Flux-Cored Convenience: The integrated non-corrosive flux core means no messy paste and no secondary cleaning in most HVAC/R repair scenarios.
• Superior Wetting: Excellent flow characteristics ensure deep penetration into aluminum alloy condensers and microchannel coils.
• Cadmium-Free Safety: Formulated for operator safety and environmental compliance without sacrificing the strength of the bond.
• Dissimilar Metal Joining: Highly effective for aluminum-to-copper brazing, a common requirement in modern high-efficiency cooling systems.
• Thermal Control: The 824°F liquidus and solidus temperature helps prevent the common "burn-through" associated with high-heat aluminum rods.

Common Questions & Technical Insights:

Can Harris AL200RC be used on all aluminum grades?
It is optimized for 1000, 3000, and 6000 series aluminum. It is not recommended for high-magnesium alloys (like 5000 series) or casting alloys where the magnesium content exceeds 2.5%, as this can lead to brittle joints.

Does the flux residue need to be removed after brazing?
Since the flux is non-corrosive, it can typically be left on the joint. However, for a clean professional finish or if the part requires painting, the residue can be brushed off easily after the joint has cooled.

What torch setup is best for Alcor Fluxed Aluminum Alloy?
An air-fuel or oxy-acetylene torch with a neutral to slightly carburizing flame is standard. The key is to heat the base metal until it reaches the 824°F threshold, allowing the flux-cored aluminum filler metal to melt upon contact with the workpiece.
