Extruded finned tubes are bimetallic tubes whose outer aluminium surface is finned by cold plastic deformation.
The general materials of base tubes about the extruded finned tube are carbon steel, copper, alloy, stainless steel; the general materials of fins about the extruded finned tube are copper, aluminum 1060/1070, aluminum alloy 6063/6061. Therefore, it is generally divided into four categories:
SA249 specification covers nominal-wall-thickness welded tubes and heavily cold worked welded tubes, with various grades intended for such use as boiler, superheater, heat exchanger, or condenser tubes.
Grade | C | Mn | P | S | Si | Cr | Ni |

TP304 | 0.08 | 2.00 | 0.045 | 0.030 | 1.00 | 18.0-20.0 | 8.0-11.0 |
Grade | Tensile Strength min | Yield Strength min | Elongation in 2" or 50mm min |

TP304 | 75ksi (515 MPa) | 30ksi (205 MPa) | 35% |
The processing technology of steel and aluminum cold-rolled fin tube consists of aluminum tube and steel pipe being processed into bimetal composite tube, and then forming fin after mechanical cold rolling.
Based on the physical characteristics of aluminum tube, the tube with steel tube as the core and the cold rolled aluminum fin are made into a finned tube. Widely used in steel, petroleum, chemical industry, machinery, shipbuilding, power stations and hospitals and food industries.
