In the automotive industry, components like exhaust systems, turbocharger housings, EGR coolers, and heat exchangers require materials that can withstand high temperatures, corrosion, and vibration without compromising on strength. Stainless steel has become a key material for such components due to its thermal stability and resistance to oxidation.

However, joining stainless steel parts with conventional welding can often lead to oxidation, stress distortion, or contamination. This is where Normantherm’s vacuum brazing technology provides a critical advantage.

The Normantherm Advantage

At Normantherm, our vacuum brazing furnaces operate in controlled, high-vacuum environments that eliminate oxidation and ensure a flux-free, ultra-clean bond. The result is a joint that maintains both mechanical strength and visual precision.

Key benefits include:

  • Oxidation-free joining for clean, bright finishes
  • Uniform temperature distribution preventing deformation
  • Superior strength and corrosion resistance
  • Improved thermal performance in automotive assemblies

Applications in the Automotive Industry

This stainless steel–to–stainless steel brazing process is widely used in the manufacturing of:

  • Turbocharger assemblies for high-temperature performance
  • Exhaust gas recirculation systems (EGRs)
  • Heat exchangers and cooling modules for electric and hybrid vehicles

By ensuring precise, reliable bonding, Normantherm supports automotive manufacturers in achieving lighter, stronger, and more efficient vehicle designs — meeting modern performance and environmental standards.
