Cold Rolled Aluminum Coil

1.Cold-rolled coil products are accurate in size and uniform in thickness. The thickness difference of sheet coil is generally not more than 0.01-0.03mm or smaller, which can fully meet the requirements of high precision tolerance.

2.Extremely thin strip that cannot be produced by hot rolling can be obtained (the thinnest can be less than 0.001mm).

3.The surface quality of cold-rolled products is superior, there is no pitting, pressing into oxide sheet and other defects that often occur in hot-rolled plate rolls, and according to the requirements of users, the production of different surface roughness of the plate rolls (gloss surface or hemp rough surface, etc.), in order to facilitate the processing of the next process.

4.Cold rolled coil distance and good mechanical properties and process properties (such as higher strength, lower yield limit, good deep drawing performance, etc.).

5.Can realize high-speed rolling and full continuous rolling, with high productivity.

Product Details

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.

Details

Cold rolled coil (annealing state) : the cold hard coil is obtained by cover annealing before rolling. After annealing, the work hardening phenomenon and internal stress are eliminated (greatly reduced), that is, the yield strength is reduced close to that before cold rolling.

Application

Cold rolled aluminum coil is suitable for aerospace industry, blow molding (bottle) mold, ultrasonic plastic welding mold, golf ball head, shoe mold, paper mold, foam forming mold, wax mold, template, fixture, mechanical equipment, mold processing.
