Product Description

Aluminum Inner Grooved Copper Tube is made of 3003/3103 al-alloy materials through extrusion and drawing that determine its better ductility.And the tooth height from 0.05mm to 0.20mm contributes to its heat conduction performance which is necessary in air-conditioners' heat exchange system.It must be a wise choice for air conditioner factories because of its lowest cost.
