What materials can be joined using a vacuum brazing furnace?
Vacuum brazing provides fluxless, oxide-free bonding when using high-grade thermal processing for stainless steels, titanium alloys, nickel-base superalloys, copper, aluminum, and ceramic-to-metal assemblies, as well as complex dissimilar metal combinations.
How do graphite and all-metal hot zones affect vacuum brazing furnace price and performance?
All-metal molybdenum or tungsten hot zones prevent carbon contamination, making them essential for high-purity medical and aerospace applications. Graphite hot zones deliver excellent thermal efficiency and rapid cycle times while offering a lower initial vacuum brazing furnace price for general industrial processing.
