The product is applied to flame brazing, high frequency brazing, resistance brazing. It is applied to the welding of copper, copper alloy, cast iron and hard alloy. The grease, oxide and dirt on the surface of metal material should be well cleaned before brazing. To have a good quality joint, brazing with brazing flux is a must.
