Industry for Use
1. The thickness is accurate and uniform. The stamping die is precise, the gap is small, the sheet thickness is too large to increase the deformation force, and the jam is caused, and even the die is cracked; if the sheet is too thin, the quality of the finished product is affected, and even the crack occurs even when the drawing is deep.
2. The surface is smooth, no spots, no flaws, no scratches, no surface cracks, etc. All surface defects will remain on the surface of the finished workpiece, and the crack defects may be deepened and expanded in the process of bending, deep drawing, forming, etc., resulting in waste.
3. The yield strength is uniform and there is no obvious directionality. Anisotropy (see plastically deformed sheet) in the drawing process such as drawing, flanging, bulging, etc., due to the occurrence of the mutual yielding, the amount of plastic deformation is inconsistent, causing uneven deformation, resulting in inaccurate forming, which will cause defective or scrap.
4. Uniform elongation is high. In the tensile test, the elongation before the sample begins to appear in the necking phenomenon is called uniform elongation. When drawing, the deformation of any area of the sheet should not exceed the uniform extension of the material, otherwise uneven deformation will occur.
