Castings are metal forming objects obtained by various casting methods, that is, the smelted liquid metal is injected into the pre-prepared casting mold by pouring, injection, suction or other casting methods, and after cooling, after grinding and other subsequent processing methods. , the resulting object of certain shape, size and properties.

There are many classification methods for castings: according to the different metal materials used, they are divided into steel castings, iron castings, copper castings, aluminum castings, magnesium castings, zinc castings, titanium castings, etc. And each type of casting can be further divided into different types according to its chemical composition or metallographic structure. For example, iron castings can be divided into gray iron castings, ductile iron castings, vermicular iron castings, malleable iron castings, alloy iron castings, etc.; according to the different casting methods, castings can be divided into ordinary sand castings, metal castings, die castings , centrifugal castings, continuous castings, investment castings, ceramic castings, electroslag remelting castings, bimetal castings, etc. Among them, ordinary sand castings are the most widely used, accounting for about 80% of all castings. And aluminum, magnesium, zinc and other non-ferrous metal castings are mostly die castings.

The properties of the casting itself directly affect the quality of the processing, and the hardness value is an important indicator to determine the processing of the casting.
1) Brinell hardness: It is mainly used to measure the hardness of castings, forgings, non-ferrous metal parts, hot-rolled billets and annealed parts. The measurement range is ≯HB450.
2) Rockwell hardness: HRA is mainly used for high hardness test pieces, to measure the hardness of materials and surface hardness higher than HRC67, such as cemented carbide, nitrided steel, etc., the measurement range is HRA>70. HRC is mainly used for hardness measurement of steel parts (such as carbon steel, tool steel, alloy steel, etc.) after quenching or tempering, and the measurement range is HRC20~67.
3) Vickers hardness: used to measure the hardness of thin parts and steel plate parts, and can also be used to measure the hardness of surface hardened parts such as carburizing, cyanidation, and nitriding.
