The Aufhauser Bare Bronze Low Fuming Brazing Rod (2.5mm \/ 3\/32″) is a high-quality general-purpose filler metal designed for the oxy-fuel brazing process. Manufactured to meet AWS A5.8 RBCuZn-C classifications, this rod is engineered to significantly reduce fuming during application, providing a clearer view of the weld pool and a safer working environment for the operator. It is an essential consumable for industrial maintenance, repair, and fabrication shops dealing with a variety of base metals.<\/p>\n
This bare rod requires the application of a suitable brazing flux to ensure proper wetting and oxide removal. The alloy composition\u2014primarily copper and zinc with additions of iron, manganese, and silicon\u2014results in a deposit with high tensile strength and excellent ductility. This makes it particularly effective for joining steel, cast iron, copper, and copper alloys (brass and bronze). The inclusion of manganese and iron specifically enhances the mechanical properties of the bond, ensuring durable repairs even under stress.<\/p>\n
Ideally suited for maintenance and repair operations (MRO), the Aufhauser Low Fuming Bronze rod flows freely and builds up easily, allowing for bridging gaps or building up worn surfaces. It is widely used for the repair of cast iron parts where fusion welding might cause cracking, as the lower heat input of brazing minimizes thermal shock. Post-braze, the deposit is easily machinable, allowing for precise finishing of bearing surfaces or visible joints.<\/p>\n
