Flat aluminum sheet

0 Comment

Flat aluminum sheet is a rectangular sheet made of rolled aluminum ingot, which is made of a variety of materials. Haomei Aluminum produces aluminum sheet specifications are quite rich, according to the alloy composition, flat aluminum sheets can be divided into pure aluminum sheet and alloy aluminum sheet. Pure aluminum sheet is mainly composed of pure aluminum, such as 1050 aluminum sheet, 1060 aluminum sheet, 1070 aluminum sheet, 1100 aluminum sheet, while alloy aluminum sheet is based on aluminum with other metal elements such as copper, manganese, magnesium, silicon, etc. to improve its physical and chemical properties, such as 2024 aluminum sheet, 3003 aluminum sheet, 5052 aluminum sheet, 5083 aluminum sheet, 5086 aluminum sheet, 6061 aluminum sheet, 6082 aluminum sheet, 7075 aluminum sheet. The flat aluminum sheet thickness ranges from 0.3mm to 500mm and the width ranges from 100mm to 2800mm.

Aluminum sheet flatness is generally controlled within a specific range, depending on the thickness, material and application of the aluminum sheet. The maximum undulation of aluminum sheet flatness should be no more than 2% of the plate thickness, and the deviation at the center of the aluminum sheet should also be no more than 2% of the sheet thickness, etc. These specifications are to ensure that the aluminum sheet will maintain a stable performance and appearance in use. This range may vary depending on the thickness and use of the aluminum sheet. Thin aluminum sheets have relatively high requirements for flatness due to their thin thickness, usually requiring a high degree of surface flatness without wrinkles, blisters, scratches and other defects.


The flatness of aluminum sheet directly affects its processing and use effect. If the flatness of the aluminum sheet is not enough, then in the processing process may appear deformation, warping and other problems, which will seriously affect the use of the product effect and quality. Therefore, during the production process, flat aluminum sheets need to meet certain flatness standards to meet the needs of applications in various fields, such as the manufacture of electronic equipment or construction materials. For specific applications, such as the printing industry, the flatness of the aluminum sheet is particularly important. Aluminum printing sheets need to have a high degree of flatness to ensure that defects such as unevenness or impurities do not occur during the printing process, thus guaranteeing the quality and aesthetics of the printed material.
