Silicon Nitride Ceramic:
The surface and internal properties of the sheet metal used for stamping have a great influence on the quality of the stamped product. The requirements for stamping materials are: accurate and uniform thickness. The stamping die is precise and has a small gap. If the thickness of the sheet is too large, it will increase the deformation force and cause jamming and even burst the die. If the sheet is too thin, it will affect the quality of the finished product and even crack during deep drawing. The surface is smooth, no spots, no scars, no scratches, no surface cracks, etc. All surface defects will remain on the surface of the finished workpiece, and the crack defects may expand deeply and widely during the processes of bending, deep drawing, and forming, resulting in waste products. The yield strength is uniform without obvious directionality. Anisotropy (see plastic deformation in the drawing, flanging, bulging and other stamping processes, due to the emergence of all-directional yielding, and the inconsistent amount of plastic deformation will cause uneven deformation and inaccurate forming. Inferior or scrap products. High uniform elongation. In tensile test, the elongation before the neck phenomenon of the sample begins to be called uniform elongation. During deep drawing, the deformation of any area of the sheet cannot exceed the uniform elongation of the material Range, otherwise uneven deformation will occur. The yield ratio is low. The ratio of the yield limit of the material to the strength limit is called the yield ratio. A low yield ratio can not only reduce the deformation resistance, but also reduce the wrinkling during drawing The tendency is to reduce the amount of springback after bending and improve the accuracy of the bending parts. The work hardening is low. Work hardening after cold deformation will increase the deformation resistance of the material and make it difficult to continue to deform. Therefore, the plate with low hardening index is generally used. Materials with a high hardening index have good plastic deformation stability (that is, more uniform plastic deformation) and are not prone to localized cracks.
properties:
High hardness, high strength, wear resistance, corrosion resistance, high temperature(1200°), good thermal diffusivity, good thermal shock resistance(avoid the temperature changing rapidly), good insulativity, low density. The comprehensive properties are best in most of structure ceramic.
