The difference between cold-rolled aluminum sheet and hot-rolled aluminum sheet in Ningbo aluminum die-casting products

The application of Ningbo aluminum die-casting products in various industries is becoming increasingly widespread, and various types of aluminum sheet materials have also emerged. Among them, cold-rolled aluminum sheet and hot-rolled aluminum sheet are two common aluminum sheet materials in aluminum die-casting products. So, what are the differences between cold-rolled aluminum sheet and hot-rolled aluminum sheet in Ningbo aluminum die-casting products?

1、 Production process

The production processes of cold rolled aluminum sheet and hot rolled aluminum sheet are different. Cold rolled aluminum sheet is formed by pressure rolling at room temperature, and its surface is relatively flat. Hot rolled aluminum plates are formed by pressure rolling at high temperatures, with relatively rough surfaces and sometimes edge cracks.

2、 Mechanical properties

Due to different production processes, there are also differences in the mechanical properties of cold-rolled and hot-rolled aluminum sheets. Hot-rolled aluminum sheets have higher strength and plasticity, while cold-rolled aluminum sheets are more fragile but have higher hardness. Therefore, it is necessary to choose appropriate aluminum plate materials in different application scenarios.

3、 Surface quality

The surface quality of cold-rolled and hot-rolled aluminum sheets processed by Ningbo aluminum die-casting is also different. The surface of cold rolled aluminum sheet is relatively flat and can be directly used for various processing and surface treatment; The surface of hot-rolled aluminum plates is rough and requires surface treatment such as pickling before use.

4、 Application occasions

Cold rolled aluminum sheet and hot rolled aluminum sheet also have differences in application scenarios. Hot rolled aluminum sheets are mainly used for high-strength parts in structural components, automotive manufacturing, aerospace, and other fields, while cold rolled aluminum sheets are mostly used in electronic components, ship equipment, chemical containers, and building decoration.

Overall, there are certain differences between cold-rolled and hot-rolled aluminum sheets in production process, mechanical properties, surface quality, and application scenarios. The selection of aluminum plate materials by Ningbo aluminum die-casting manufacturers needs to be determined based on specific circumstances. Ningbo aluminum die-casting product manufacturers need to provide aluminum sheet materials that meet customer requirements to ensure stable and reliable product quality.
