Aluminum inner grooved tube

The product through extrusion and drawing that determine its better ductility. And the tooth height from 0.05mm to 0.25mm contributes to its heat conduction performance which is necessary in air conditioner’s heat exchange system. It must be a wise choice for air conditioner factories because of its lowest cost.
