Finbraze® Finned Tubing


Celebrating 20+ Years Since 1993

The brazed finned tubing service from Fin Tube Products, Inc. creates a metallurgical bond between the tube and fin, making it the most suitable bond for higher temperature applications. FINBRAZE® bonding between the tube and the fin ensures a stress-free, uniform, and non-porous contact. This bonding allows for thinner tube walls compared to a welded fin to tube joint. The FINBRAZE® process is done in house with our Controlled Atmospheric Brazing Furnace. There are numerous advantages to the FINBRAZE® production of finned tubing.

  • The use of dissimilar metals which cannot be welded such as copper fins on stainless steel tube.
  • The use of thinner (less expensive) tube walls that are not available when welded.
  • The finned tubes can be formed over the fins after brazing.
  • Brazing is performed at a uniform temperature eliminating stress at the joint areas.
  • The use of our in house Controlled Atmospheric Brazing Furnace allows for complete control over the production of your tubes.
  • No Arcing. Eliminating the "Hot Spots" at the tube to fin joints as may occur in welded finned tube.

Our FINBRAZE® tubing can be seen in heat exchangers across many industries including Aerospace, Automotive, Medical, Petro-Chemical, Cryogenic, and Electrical to name a few.
