Aluminum Coil

Our company has produced cold rolled aluminum coil for many years, and many countries in the world have

 had cooperation, cooperation with customers are praising our cold rolled aluminum coil quality is good and 

cheap, the customer said that we are a trustworthy company. Next I will introduce cold rolled aluminum coil. 

The aluminum coil is first molded by casting and rolling machine and then processed by drawing Angle. After 

processing, the aluminum coil is sheared. This metal product is called aluminium coil. It is widely used in 

electronic devices, packaging, engineering construction, mechanical equipment and other fields. Cold rolled 

coil (annealing state) is the cold hard coil before rolling after cover annealing, annealing its work hardening 

phenomenon, internal stress is eliminated (greatly reduced), that is, the yield strength is reduced close to the 

cold rolled. The condition of cold rolled aluminum plate is to process the hot rolled aluminum plate at room

 temperature. After processing, the hot rolled aluminum plate is processed by continuous cold deformation, 

and the cold rolled aluminum plate is formed after processing. The processing process of cold rolled aluminum 

plate leads to its poor mechanical properties and high hardness, so cold rolled aluminum plate is mostly used 

for mold. The main solution of cold rolling is not hot strengthening materials, so his requirements are relatively 

high, generally on the surface provisions are higher, and single zero foil double zero foil and other thin 

materials can only be cold rolling. The production process of cold rolling aluminum coil is slitting-pickling-cold 

rolling-cleaning-annealing- leveling (or tensile correction)-slitting-packing. Two rolling process (or more rolling 

process) cold rolling production process is cold rolling-cleaning- annealing-cold rolling-cleaning-annealing-

leveling (or tensile correction)- stripping-packaging. Hard material: delivery after cold rolling cold rolled aluminum 

coil market price is about 1700-2500 DOLLARS, the market is broad. And hot rolled aluminum coil has many 

advantages, such as Cold-rolled coil products are accurate in size and uniform in thickness.
