serial number	name,	meaning
1	, casting sex	metal materials can be used to cast a qualified castings called castability. The castability include mobility, contraction and segregation tendencies. Mobility refers to the ability of the liquid metal is full of mold, and mobility as possible, the easier casting of thin and delicate casting, shrinkage refers to the degree of volume shrinkage in the casting solidification, the smaller the shrinkage deformation smaller solidification of the casting. Segregation refers to the non-uniform chemical composition, the segregation of the more serious the more uneven parts of the performance of the casting, the casting of smaller reliability.
2	machinability	metal material cutting means metal cutting processing capacity, but also refers to the metal processing and the degree of difficulty to meet the requirements of the workpiece . Usually used to evaluate the machinability of the metal can after cutting the surface roughness, cutting speed and tool wear.
3	the weldability	welding is a metal commonly used welding methods in the specific structure and process conditions expected quality requirements of the welded joints performance. Weldability is generally based on changes in the crack sensitivity during welding and weld zone mechanical properties to determine.
4	malleability,	malleability of the material will withstand hammer forging, rolling, drawing, extrusion process is to change shape without cracks performance . It is actually a manifestation of the metal plastic is good or bad, the higher the metal materials, plastic deformation resistance of the smaller, the malleability, the better. Malleability is good or bad depends on the chemical composition of the metal microstructure, deformation temperature, deformation rate and stress state and other factors.
5	the stamping sex	stamping is metal after stamping deformation without the occurrence of cracks and other defects in the performance. The manufacture of metal products to go through the stamping process, such as car shell, enamel products, billets and pans, pots, Yu, pots and other daily necessities. Must have in order to ensure the smooth progress of the quality of products and processes for stamping of sheet metal with the qualified stamping performance.
6	, top malleability	forging is a metal material to withstand playing riveting, upsetting a top performance of the upset deformation. Metal forging, upsetting test determination.
7	, cold-formed	metal materials can withstand bending without breaking performance at room temperature, called cold bending resistance. Cracks can withstand before bending the greater the degree of cold bending properties of the material as possible.
8	heat, manufacturability	heat treatment is metal or alloy in the solid state within a certain degree of heating, insulation and cooling, to change the internal organization of the metal or alloy, required for the performance of a process operation. The heat treatment process refers to the ability to change its organization and performance of metal heat-treated, including hardening, hardenability and temper brittleness.
