Answering the question of material hardness after vacuum brazing

When vacuum brazing 4340 steel with PDC (polycrystalline diamond composite), it is a technical challenge to ensure that the hardness of 4340 material does not decrease. 4340 steel is a high-strength alloy steel, and its hardness depends on vacuum quenching and vacuum tempering heat treatment. The...

Vacuum brazing process for copper

Copper has excellent electrical conductivity, thermal conductivity, corrosion resistance, ductility and certain strength. Adding various alloy elements to copper can improve its corrosion resistance, strength and improve machining performance. Parent material: 1. Pure copper (divided into oxygen ...

Understand the influence of vacuum degree on the quality of vacuum brazing products

Aluminum vacuum brazing is a welding process performed in a vacuum environment. The core of the process is to use heat to melt the brazing material and fill the tiny gaps between aluminum or aluminum alloy parts, and then form a strong and sealed connection after cooling. This process is widely u...

Vacuum furnace maintenance method

The main reasons for the discoloration failure of vacuum furnace products include the following points The discoloration failure of vacuum furnace products is mainly caused by oxidation, which may be due to insufficient vacuum, contamination or system leakage. Studies have shown that maintaining ...

Vacuum brazing of high temperature ceramic and metal joints

1. Vacuum brazing of structural ceramics Structural ceramics (such as Si₃N₄, SiC, Al₂O₃) have been widely used in mechanical processing, chemical industry, electronics, aerospace and other fields due to their excellent high temperature resistance, corrosion resistance and wear resistance. The rel...

Relationship between material surface roughness and vacuum brazing

Surface roughness is one of the important factors affecting the quality of vacuum brazing, especially in terms of the flow and wetting behavior of the brazing material and the performance of the joint. Vacuum brazing is a brazing process performed in a vacuum environment and is widely used to con...

Tips on controlling and influencing vacuum degree in vacuum brazing

Vacuum brazing is a brazing process performed in a vacuum environment. It is widely used in aviation, aerospace, nuclear energy and electronics, and is particularly outstanding in high-precision and high-demand applications. The core is to provide a low-pressure environment to avoid oxidation and...

Vacuum furnace manufacturers tell you the common methods of cleaning vacuum brazing furnaces

Oven Dry Run Cycle: This is a standard practice that involves heating the furnace without a load to burn off contaminants. According to the vacuum furnace maintenance procedure, it is recommended to heat the furnace to at least 1200°C (2200°F) and hold it for 30-60 minutes. However, for vacuum br...

Vacuum brazing technology of aluminum cold plate

Vacuum brazing technology Vacuum brazing is a high-precision process for joining metal parts in a vacuum environment by heating and using a brazing material with a lower melting point than the base material. It is widely used in the manufacture of aluminum cold plates. The heating stage is a key ...

Improvement of Vacuum Brazing Technology for Titanium Alloy Plate-Fin Heat Exchanger

A specific process improvement example for multi-layer vacuum brazing of 70-layer titanium alloy (Ti-6Al-4V) plate-fin heat exchangers. The 70-layer structure significantly increases the difficulty of heat transfer, brazing seam consistency requirements and deformation control challenges, so more...
