Vacuum Heat Treating

Heat treating parts in a vacuum furnace is not a new technology, but it is becoming more preferred by tool and die shops, mold makers, and industries such as forging, casting, aircraft and plastic molding. In the vacuum environment, no surface modifications such as carburization, oxidation, scaling or decarburizing occur. Parts emerge from the vacuum furnace bright and clean and in some cases, ready to use.

PROCESSING
At Fused Metals Inc. quality processing is of prime concern. Consistency, repeatability, and traceability are achieved through programmable control of furnace cycles, proper fixturing and positioning of parts within the furnace, using load and control thermocouples to monitor both the part and the furnace temperature, following textbook heat treating procedures, issuing process certifications with each order and recording all critical parameters. Simply put, Fused Metals Inc. believes that a proper and better job can be done - and it's been proven.

Vacuum Brazing

Brazing parts in a vacuum furnace allows joining of assemblies under ultraclean conditions. With no oxygen present, fluxes are not required, therefore leaving the braze joint free of porosity and oxide inclusions. More accurately called diffusion bonding, the brazing alloy penetrates the base metal, joining the parts into a single piece. Torch brazing with low temperature silver solder is more similar to gluing the parts together. Vacuum brazing is ideally suited for assemblies, where the contact surfaces are not accessible, once assembled. Since brazing alloys are available in wire, powder, paste, tape and foil, they can be applied to parts prior to assembly. The result is a part brazed from the inside out, not just on the surface.

PROCESSING
The clean environment inside the vacuum vessel results in the brazing alloy being allowed to flow over completely clean, contaminant and oxide free surfaces. This results in brazed joint strengths that can exceed the strength of the base metal. Heat treatable alloys can be brazed and hardened in one cycle due to the wide range of brazing alloys available that melt at varying temperatures. Dissimilar metals can also be brazed with the appropriate alloy selection. The big advantage is to design with vacuum brazing in mind, instead of welding as a last resort. With more than 25 years of brazing experience Fused Metals Inc. can be part of that design.
