Reputation depends on quality, quality comes from Hard!
Silicon Nitride Ceramic:
The surface and internal properties of stamping sheet material have a great influence on the quality of stamping products. The requirements for stamping materials are: precise and uniform thickness. The stamping die is precise and has a small gap. If the thickness of the sheet is too large, the deformation force will be increased, and the material will be jammed, and even the die will be swelled. If the sheet is too thin, it will affect the quality of Infrared Cordierite Honeycomb Ceramics Porous Gas Burner 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 extend deep and wide during the process 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 Infrared Cordierite Honeycomb Ceramics Porous Gas Burner processes, due to the occurrence of all-directional yielding, the inconsistent amount of plastic deformation will cause uneven deformation and inaccurate forming. Inferior or scrap products. High uniform elongation. In the tensile test, the elongation before the neck phenomenon of the sample begins to be Infrared Cordierite Honeycomb Ceramics Porous Gas Burner 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 wrinkle during drawing Tendency to reduce the amount of springback after bending and improve the accuracy of bending parts.
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.
