ASTM A179 Carbon Steel Wound Fin Tube With Al1060 Fin Strip For Air Cooler
ASTM A179 Carbon Steel Wound Fin Tube With Al1060 Fin Strip For Air Cooler
Product Overview
ASTM A179 carbon steel wound fin tube with Al1060 aluminum fin strip is a widely used heat transfer element in air cooler systems. The base tube (A179) is seamless cold-drawn low-carbon steel with excellent heat transfer performance and good machinability. The fins are made of high-purity Al1060 aluminum, known for superior thermal conductivity, lightweight nature, and strong corrosion resistance. The wound fin type involves helically wrapping the aluminum strip onto the carbon steel tube, ensuring firm bonding and increased heat exchange area.
