Extruded Finned Tubes ASTM A179 With Aluminum 1060 Fins For Consensers and Air Coolers Introduction
An Extruded Finned Tubes ASTM A179 With Aluminum 1060 Fins is a specialized heat exchanger component designed to enhance heat transfer efficiency. It consists of a base tube made of ASTM A179 minimum-wall-thickness, seamless cold-drawn low-carbon steel and fins made of Aluminum 1060, which are are formed by extruding heated metal through a die to simultaneously shape the base tube and fins in a single seamless process, enhancing heat transfer and mechanical strength.
