What Materials Are Used for Finned Tubes?

For Aluminum L-Foot finned tubes, the fin material is aluminum, either 1100-0 or 5005.  The tube material is generally carbon steel, stainless steel, or brass; however the tube can be of any material.

For Welded Helical Solid  and Welded Helical Serrated finned tubes, the fin and tube materials can be any combination that can be welded together using the GMAW (gas-metal-arc-welding) process.

For Welded Longitudinal finned tubes, the fin and tube materials can be any combination that can be resistance welded together.

The materials chosen for a given application are a function of service temperature, corrosive environment, and/or erosive environment.  Common tube materials used for our welded product lines include: carbon steel, carbon moly, chrome moly, stainless steel, Inconel, and Incoloy.  Common fin materials include: carbon steel; stainless steels of types 304, 310, 316, 321, 409, and 410; Nickel 200, and Inconel.
