The electric heating vacuum brazing furnace is suitable for welding various materials and has a wide range of applications, mainly due to its characteristics of no oxidation, precise temperature control, and strong material compatibility in a vacuum environment.

1. Aluminum and aluminum alloys

Characteristics: Aluminum and aluminum alloys have the advantages of low density, good thermal conductivity, and corrosion resistance, but they are prone to oxidation during welding.

Applicability: Vacuum brazing furnaces can effectively prevent oxidation, achieve high-quality welding of aluminum and aluminum alloys, and are widely used in fields such as aerospace and automotive manufacturing.

2. Copper and copper alloys

Characteristics: Copper and copper alloys have good conductivity, thermal conductivity, and corrosion resistance, but they are prone to porosity and cracking during welding.

Applicability: The vacuum brazing furnace can effectively reduce the occurrence of pores and cracks, improve welding quality, and is suitable for industries such as electronics and power through precise temperature control and vacuum environment.

3. Stainless steel

Characteristics: Stainless steel has excellent corrosion resistance, high temperature strength, and aesthetics, but it is prone to thermal cracking and intergranular corrosion during welding.

Applicability: The vacuum brazing furnace can accurately control the welding temperature and time, reduce the risk of hot cracking and intergranular corrosion, and is suitable for fields such as food processing, chemical engineering, and medical devices.

4. Alloy steel

Characteristics: Alloy steel has high strength and hardness, but it is prone to quenching and cold cracking during welding.

Applicability: Vacuum brazing furnaces can effectively reduce the occurrence of hardened structures and cold cracks through slow cooling and precise temperature control, improve the toughness and strength of welded joints, and are suitable for industries such as mechanical manufacturing and shipbuilding.

5. Titanium alloy

Characteristics: Titanium alloy has high strength, low density, and good corrosion resistance, but it is prone to react with elements such as oxygen and nitrogen during welding, which affects the welding quality.

Applicability: The vacuum environment of the vacuum brazing furnace can effectively avoid the reaction between titanium alloy and elements such as oxygen and nitrogen, achieve high-quality welding of titanium alloy, and is suitable for fields such as aerospace and medical equipment.

6. Heterogeneous materials

Characteristics: When welding dissimilar materials, due to significant differences in material properties, stress concentration and cracking are prone to occur.

Applicability: Vacuum brazing furnaces can effectively reduce stress concentration and crack formation through precise temperature control and vacuum environment, achieving high-quality welding of dissimilar materials such as aluminum and copper, stainless steel and titanium alloys, etc.
