Product Description Silicon Nitride Ceramic PinSilicon NItride Ceramic welding pins made of silicon nitride significantly increase service life and enable high levels of precision and greater accuracy over extended periods in projection welding. Metal welding pins often need to be replaced several times a day due to wear and adhering slag, whereas centring pins made of silicon nitride ceramic only need to be replaced about once a month. Ceramic materials have long replaced metal in the production of welding pins, which ensure a perfect fit for sheet metal and nuts in projection welding and are subject to temperatures of up to 800°C. Gas-pressure sintered silicon nitride ceramics from INNOVACERA are at a distinct advantage here:> Extreme hardness and flexural strength> High thermal shock resistance> Electrical insulation> Temperature resistance> High tensile strength and compressive strength> Fewer cold welds> No welding spatter adhesion Silicon Nitride Ceramic Properties 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 positionersWhy 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
