The method of pouring the molten liquid metal into a casting cavity shaped to match the shape of the part, and obtaining a cast product after cooling is known as casting. Casting properties typically include fluidity, shrinkage, porosity, compositional segregation, gas absorption, casting stress, and susceptibility to cold cracking
The casting performance of metal materials refers to the ability of a metal to produce qualified castings using casting methods, including characteristics such as fluidity, shrinkage, and tendency to segregation.
Is this metal material suitable for casting?
It refers to certain process properties that determine whether a metal or alloy is suitable for casting, mainly including flowability and the ability to fill the mold； Contractionality, the ability of a casting to shrink in volume during solidification ； Segregation refers to unevenness in chemical composition.
Flowability and shrinkage properties of metals
The casting performance of metal materials refers to the ability of a metal to produce qualified castings using casting methods, including characteristics such as fluidity, shrinkage, and tendency to segregation. Fluidity refers to the ability of liquid metal to fill the mold cavity ； Contraction refers to the degree of shrinkage that occurs when a metal solidifies from a liquid state to a solid state ； The tendency to segregation refers to the degree of unevenness in chemical composition and microstructure that occurs within a metal after it solidifies.
