Brazing-heating by the most suitable method

Brazing-heating application in a furnace can be economic for processing many parts at a time or for performing many joints at once in a large and complex part. While many furnaces are heated by electric elements , gas or flame may be used for Brazing-heating provided the flame do not impinge directly on the work load....<<more>>

Vacuum brazing. It consists in combining elements with the use of a brazing material. Prepared elements with applied brazing material are placed in a vacuum furnace and heated up to brazing temperature (from 900 to 1200C) higher than liquidus temperature, held for a short time (10min) and slow cooling to solidus temperature....<<more>>

What are the advantages of vacuum heat treatment technology

Vacuum heat treatment is a metal heat treatment process in which metal workpieces are heated under 1 atmosphere (i.e., negative pressure). The anaerobic heat treatment of vacuum heat treatment can avoid the workpiece oxidation and decarbonization, greatly improve its hardness, reduce brittleness, and degrease degassing....<<more>>
