Introduction

Vacuum aluminum brazing furnaces are specialized thermal processing systems designed to meet the growing demands of lightweight metal joining, particularly for aluminum and aluminum alloy components. These furnaces provide an oxygen-free, contamination-free environment essential for fluxless brazing or brazing with low-temperature aluminum-based fluxes. The operating temperature is 750°C. They are widely used in automotive, aerospace, heat exchangers, electronics, and refrigeration systems, where high-strength, leak-tight joints and clean surfaces are critical.

Common Applications

• Aluminum heat exchangers (radiators, condensers, evaporators)
• Electric vehicle battery cooling systems
• Aerospace components
• Refrigeration and HVAC assemblies
• Electronics enclosures with integrated cooling

Key Features of Our Vacuum Aluminum Brazing Furnace

Stainless Steel Furnace Chamber

Robust and corrosion-resistant, the chamber is designed for long-term operation in high-vacuum environments.

High Uniformity Electric Heating

Electric heating elements (typically electric alloy tubes) are distributed evenly to ensure temperature uniformity up to ±5°C, which is critical for large or complex assemblies.

Maximum Operating Temperature: 750°C

Optimized for aluminum brazing and compatible with common aluminum-silicon and zinc-based filler materials.

Advanced Control System

• HD touchscreen HMI with user-friendly interface.
• PLC-controlled automatic operation, offering high precision, programmable ramp/soak profiles, and data logging.

High Vacuum Capability

Equipped with mechanical pump + diffusion pump system, capable of achieving ultimate vacuum levels of 7 × 10⁻³ Pa under cold, no-load conditions.

Optional Quick Cooling System

Enables rapid cooling from brazing temperature to below 180°C in less than one hour, significantly improving cycle time and productivity.

Environmentally Friendly and Energy Efficient

Vacuum brazing is cleaner, more energy-efficient, and does not emit harmful gases compared to conventional brazing methods.
