Product Description

3003 Micro-channel tubes

1,Introduction of 3003 Micro-channel tubes
3003 aluminum alloy is an AL-Mn series alloy, which is the most widely used type of rust-proof aluminum,it has good corrosion resistance and weldability, and is easy to form,it can be used to produce required high plasticity and good welding of Porous microchannel aluminum flat tubes working in liquid or gaseous media.Using of the refined 3003 aluminum rods, going through of Hot extrusion, and zinc sprayed on the surface,so as to produce out 3003 Micro-channel tubes, which are mainly used in various refrigerant air-conditioning systems as pipe parts carrying new environmentally friendly refrigerants.
