Solar Flux is a complex chemical compound that when mixed with alcohol forms a formulation that is useful in cleaning the surface of a metal, protecting the back of the weld joint from oxygen and dissipating heat and unwanted oxides. It is available in a fine powder form.
Solar Flux is of two types: Type B and Type I.
Type B Solar Flux is ideal for welding metals like stainless steel and alloy steels. Whereas, Type I Solar Flux is used for welding high nickel superalloys.
