Casting performance: it refers to some technological properties of whether a metal or alloy is suitable for casting, mainly including flow performance and mold filling capacity; shrinkage and volume shrinkage capacity of castings during solidification; segregation refers to the inhomogeneity of chemical composition.
Welding performance: refers to the characteristics that two or more metal materials are welded together by heating or heating and pressure welding method, and the interface can meet the purpose of use.
Performance of jacking gas section: refers to the performance of metal materials that can withstand upset without cracking.
Cold bending performance: refers to the metal material can withstand bending and not rupture at room temperature. The bending degree is generally expressed by the ratio of bending angle α (external angle) or bending center diameter D to material thickness a. the larger a or the smaller D / A, the better cold bending property of the material is.
Stamping performance: the ability of metal materials to withstand stamping deformation without cracking. Stamping at room temperature is called cold stamping. The test method was cupping test.
Forging performance: the ability of metal materials to withstand plastic deformation without cracking in forging process.
