金属材料 制耳试验方法
Application Summary AI generated
This standard specifies a method for determining the earing tendency of metallic sheets and strips after deep drawing. It is applied in the metallurgical industry to evaluate the planar anisotropy of materials, particularly for aluminum, steel, and other alloys used in automotive body panels, beverage cans, and household appliances. The test measures the height variations of ears formed on a drawn cup, helping manufacturers control material quality and optimize forming processes.
