1100, 1050, 1060,3003 Ultra Precision Micro-channel Aluminum Flat Tubes
1.Introduction of Ultra Precision Micro-channel Aluminum Flat Tubes
Micro-channel aluminum flat tube is a thin-walled porous flat tube material using refined aluminum rods, hot extrusion, and zinc sprayed surface treatment. The Ultra Precision Micro-channel Aluminum Flat Tubes produced by our company have very precise dimensions and wall thickness as well as the scope of surface quality control, it is widely used in condensers and evaporators with relatively high requirements such as automotive air conditioners and civil air conditioners. It has the characteristics of extremely small deviation range and extremely high surface finish. In addition, our company has a domestic leading straightening and cutting process to ensure the precision of the end face quality and product consistency of the Ultra Precision Micro-channel Aluminum Flat Tubes produced by our company.
