Contact SupplierBrazing aluminum with Fusion paste braze alloys has been popular since 1982. There are four basic challenges when brazing aluminum:
• Brazing Alloys Melt Close to Melting Point of Base Metals
• Aluminum Oxides Form Rapidly and Are Very Tenacious
• Control of Heat During Joining
• Obtaining the Correct Joint Clearance
Fusion has several paste alloys for brazing aluminum in open air, using conventional heating techniques and automated processes. Since the melting range of Fusion filler metals is very close to the base metals themselves, control of heat is most important. Both water washable and non corrosive flux formulations permit aluminum brazing of several commercially available aluminum base metals.
