What heat treatment furnace type is used for die cast aluminum brazing?

Die cast aluminum brazing (also known as brazing or brazing) is the process of connecting two pieces of metal together by heating the filler metal to a melting temperature without melting the substrate. The heat treatment after brazing is mainly aimed at eliminating internal stress, improving joint strength, and optimizing material properties.

The following are several types of furnaces and their characteristics suitable for post brazing heat treatment of die cast aluminum:

1. Box Furnaces
Features:
Temperature uniformity: The box furnace has good temperature uniformity and can accurately control the temperature distribution during the heat treatment process.
Multipurpose: Suitable for various heat treatment processes, such as annealing, aging, solid solution treatment, etc.
Controllable atmosphere: Some advanced box furnaces can be equipped with an atmosphere control system to provide inert gas or protective atmosphere to prevent oxidation.
Application:
Suitable for heat treatment of small and medium-sized workpieces.
Commonly used in laboratories and small batch production.

Selection Guide
When selecting a furnace suitable for post brazing heat treatment of die cast aluminum, the following factors should be considered:
Workpiece size and batch size: Select the appropriate furnace type based on the size and production batch of the workpiece.
Temperature requirement: Ensure that the furnace can reach and control the required heat treatment temperature.
Atmosphere requirements: Choose a furnace with atmosphere control function according to the process requirements to prevent oxidation and pollution.
Heating and cooling rate: Choose a furnace with fast heating and cooling capabilities to improve production efficiency.
Equipment cost and operating cost: Taking into account the initial investment and long-term operating cost of the equipment, choose a furnace with high cost-effectiveness.
By carefully evaluating these factors, a suitable heat treatment furnace can be selected to ensure the smooth progress of the post brazing heat treatment process of die cast aluminum and the quality of the final product.Click to learn more heat treatment furnace!
