When it comes to aluminum brazing, the flux makes the difference. Our potassium fluoroaluminate-based (KAlF₄) flux solutions create durable, leak-tight, corrosion-resistant bonds that stand the test of time.

We supply critical industries where reliability isn’t negotiable:

• Automotive: cooling systems, heat exchangers, lightweight components
• Refrigeration and cooling technology – e.g., for the manufacture of heat exchange systems
• White goods and electrical appliances: long-lasting, corrosion-proof assemblies

Our portfolio includes powder fluxes, flux pastes and paints as well as custom blends tailored to customer needs that meet your specific requirements. GELSENCHEM’s brazing fluxes hold all relevant certificates and approvals.
