Characteristics of cold-rolled and hot-rolled aluminum sheets

The cold-rolled aluminum plate is machined from the hot-rolled aluminum sheet at a normal temperature. Koudwalsen wordt vergeleken met koudwalsen, de mechanische eigenschappen zijn relatief slecht, de hardheid is te hoog, dus de koudgewalste aluminiumplaat wordt gebruikt voor schimmels, and hot-rolled aluminum plate is deep, and the bending performance is better, so it is suitable for deep processing.

How do you distinguish between cold-rolled aluminum plates and hot-rolled aluminum plates?

  • Different production processes: Cold rolling is made by casting machine (8mm dikte) made by cold rolling machine, hot rolling has aluminum ingot (400-500mm heated thickness) made by hot rolling mill at high temperature
  • Different raw material supply: the difference between the two is that the blank supply is different. The hot-rolled blank casting aluminum ingot is heated and rolled into rolls for cold rolling, while the cold-rolled blank is cast and rolled into rolls for cold rolling
  • Different performance: hot rolled aluminum plate surface quality, mechanische eigenschappen, ductiliteit, goede oxidatie-effect. Tegelijkertijd, the aluminum plate is generally processed by an aluminum plate, which is naturally affected by the performance of the aluminum plate
  • Different uses: cold-rolled aluminum plate is used for mold, the hot-rolled aluminum plate is suitable for stamping and drawing
