The ship is the main water vehicle, while the ship refers to the giant sea-going vessel. Due to the low density of aluminum and aluminum alloys, about 1/3 of steel, strong corrosion resistance to seawater and good processing and formability and weldability, aluminum has many advantages as a shipbuilding material. Good development prospects. The ship is developing in the direction of aluminum, and the application of marine anodized Alumium Angle extrusions is expanding day by day.


 
 .Henan Chalco has an ultra-long aluminum anodic oxidation treatment within 30m, the longest large-scale oxidation line in China, and undertakes the anodic oxidation treatment of aluminum profiles for aluminum parts. There are two 630-ton and 1250-ton profile production lines; aluminum alloy anodizing line; 7-meter oxidation tank and 20-meter oxidation tank (large-scale marine aluminum alloy and special oxidation tank for outfitting) each. The main products are aluminum round tubes, special-shaped tubes, decorative profiles, marine anodized Alumium Angle extrusions, solar water heater profiles, clip radiator profiles, textile machinery profiles, and printing and dyeing machinery profiles. And copper-aluminum composite finned tube, iron-aluminum composite finned tube, seamless aluminum tube, drawn aluminum tube, etc. It is widely used in power electronics, transportation, machinery, textile, printing and dyeing machinery and other industries.
