What materials are suitable for vacuum brazing furnaces?

Suitable for brazing materials such as aluminum alloys, titanium alloys, stainless steel, and high-temperature alloys, especially in high-precision fields like aerospace, semiconductors, and automotive components.
How does vacuum level affect brazing quality?

Higher vacuum levels effectively remove oxide layers, ensuring that the brazed joint is free of porosity and contaminants, thus improving joint strength and sealing properties.
How is the heating and cooling rate controlled in the furnace?

The furnace features multi-stage temperature programming, with adjustable heating rates (e.g., 1-20°C/min). Cooling can be accelerated through a water cooling system or inert gas circulation, providing process flexibility.
Is the energy consumption of the brazing furnace high?

The furnace uses nano-grade insulation materials and high-efficiency heating elements, reducing energy consumption by 30-40% compared to traditional models, making it more economical for long-term use.
Can the furnace be customized for special sizes or functions?

Yes, we offer non-standard customization, including furnace chamber size, temperature zones, and gas line configurations, with delivery in as little as 15 days.
Is technical support available in a timely manner?

We provide 24/7 global technical support with a 4-hour response time for urgent issues, ensuring minimal disruption to your production.
