Alcor Zinc Aluminum Brazing Filler Metal

Alcor zinc-aluminum brazing filler metal is developed for low-temperature joining of aluminum base metals where traditional aluminum brazing alloys operate too close to the base metal melting point. By working at lower temperatures, it reduces the risk of overheating and distortion of aluminum components during brazing.

The filler metal contains an internal cesium-fluoroaluminate flux core that provides controlled flux release and protects the brazed joint throughout the heating process. The flux residue is non-corrosive, meaning post-brazing cleaning is typically unnecessary, making it efficient for production and repair operations.

Manufacturing follows Harris Products Group engineering standards to ensure consistent performance and joint reliability in industrial applications.

FAQs

Why is Alcor suitable for aluminum brazing?
It operates at lower temperatures than typical aluminum alloys, reducing the risk of overheating base materials.

Does it require external flux during brazing?
No, it contains an internal flux core that releases flux during heating.

Is post-braze cleaning necessary?
In most cases, cleaning is not required because the flux residue is non-corrosive.

Who manufactures the alloy standard?
It is produced according to Harris Products Group engineering standards.
