No. ALB182A-253-70 is a low-temperature Aluminum brazing paste. This brazing paste can be used in torch brazing, induction brazing and controlled atmosphere brazing. No. ALB182A-253-70 creates a brazed bond with 6000-series and 5000-series Aluminum. This product is a brazing paste, meaning it is provided as a metal-loaded, Zinc-Aluminum brazing paste with a 70% metal load and a flux component. The flux used in this brazing paste is based on Cesium Fluoroaluminate, a flux system that is particularly effective for low temperature Aluminum brazing. Due to this brazing paste’s ability to effectuate brazing at temperatures of 436-520°C (817-986°F), it is the ideal choice for brazing to Aluminum, such as the 6000-series, without the risk of melting or causing damage to the base Aluminum.
At brazing temperatures, No. ALB182A-253-70 breaks up the tenacious Aluminum surface oxides and enables the brazing pastes Zinc-Aluminum alloy to flow and create a strong braze joint to the surface of the Aluminum. The viscosity of this brazing paste allows it to be dispensed in a controlled fashion via automatic or manual dispensing units. The brazing paste can also be spread at the desired location using various implements. Assemblies made with this Aluminum brazing paste are considered to be “no-clean,” meaning no post-braze cleaning is necessary. If post-braze cleaning is desired, then a simple water-power flush should remove flux residues. This product is available in syringes and jars of various sizes.
