Product Description Silicon Nitride Ceramic Weld PinInnovacera manufactures Silicon Nitride (Si3N4) Ceramic weld location and control pins for use in resistance welding. These are used in the metal forming industry to allow precise welding of nuts to sheet metal. Due to ceramic's high hardness and durability, metal can't compete with it in insulating properties, resistance to temperature changes, and minimal wear. Another advantage of using ceramics as centering pins is their smooth polished surface, which prevents welding spatter from adhering. However, when welding pins made of commonly used zirconia ceramics, the service life does face a limit. This material also cannot withstand the currents in projection welding and the required 800°C operating temperature over time, so it wears out. And centering standard molds made of silicon nitride ceramic is a good choice. Silicon nitride ceramic weld location pins have the following advantages:1.High-temperature stability2.Corrosion resistance3.High hardness and wear resistance4.High precision Properties UnitsSilicon Nitride (Si3N4) HPSi3N4GPSi3N4MechanicalDensityg/cm33.24~3.283.24~3.26 Color--GrayGray Water Absorption%00 Vickers HardnessGpa1414 Flexural Strength(20°C)Mpa850-900750-800 Compressive Strength(20°C)Mpa30003000ThermalThermal Conductivity(20°C)W/m.K4222 Thermal Shock Resistance(20°C)Δ T(C)617605 Maximum Use Temperature°C15001500ElectricalVolume Resistivity(25°C)Ω.cm---- Silicon Nitride Ceramic 4 Types:* Reaction-Bonded Silicon Nitride (RBSN)* Hot Pressed Silicon Nitride (HPSN)* Sintered Reaction-Bonded Silicon Nitride (SRBSN)* Sintered Silicon Nitride (SNN)Si3N4 Features.Very low density .High wear resistance and corrosion resistance .High temperature resistance .Good flexural strength and high fracture toughness .Very good thermal shock resistance .Dimensional stability and aging resistance .Excellent sliding properties (tribology) .Biocompatibility (for use in hygiene and the food and .beverage industry) Typical Silicon Nitride Uses:.Rotating bearing balls and rollers .Cutting tools .Engine moving parts - valves, turbocharger rotors .Engine wear parts - cam followers, tappet shims .Turbine blades, vanes, buckets .Metal tube forming rolls and dies .Precision shafts and axles in high wear environments .Weld positioners Product ClassificationCompany ProfileWhy Choose UsProduct packagingBrowse More ProductsSEND MEIf you are interested in our products, please click here to send me an inquiry, and I will reply you within 8 hours
