1、 Casting performance: refers to whether the metal or alloy is suitable for casting process performance, mainly including flow performance and full mold capacity; Shrinkage volume during solidification; Segregation refers to uneven chemical composition.

2、 Top gas section performance: refers to the ability of metal materials to support forging without fracture.

3、 Cold bending performance: This refers to the performance that metal processing parts can withstand bending without damage at room temperature. The degree of bending is usually determined by the bending angle of the core α (outer corner) or the ratio of diameter D to material thickness a, the larger or smaller d/a, the better the cold bending performance of the material.

Which hardware processing company is better

4、 Stamping performance: the ability of metal materials to withstand stamping deformation without fracture. Normal temperature pressing is called cold stamping. Pass the cupping test.

5、 Forging performance: the ability of metal materials to withstand plastic deformation without cracking during forging.

6、 Weldability: refers to the welding of two or more metal materials by metal or hot pressing welding. The interface can meet the use purpose.
