Soldering of iron and copper-based metals in a continuous non-oxidizing furnace.

Beautiful brazing of iron and copper-based metals! Achieve a finish with enhanced functionality and durability! Mass production is possible with furnace brazing.

In a continuous non-oxidizing furnace, brazing can primarily be performed on iron-based and copper-based base materials. Suitable filler materials are selected for the base materials to achieve a more beautiful and high-strength finish. When brazing in the furnace, reducing gases such as "hydrogen gas" and "DX gas," as well as inert gases like "nitrogen gas" and "argon gas," are used as the atmosphere inside the furnace. When iron oxide is heated in DX gas, hydrogen and carbon monoxide react with the iron oxide, resulting in a reduction reaction. Hydrogen and carbon monoxide are taken from the iron oxide, turning into water and carbon dioxide, and the iron oxide is reduced back to iron. (See image) By performing heat treatment in a sufficient reducing atmosphere, not only does wettability improve, allowing for good brazing and other processing, but it also prevents discoloration due to oxidation, resulting in shiny products.
