Silicon nitride SL200B Highest possible precision in projection welding At a glance Silicon nitride SL200B: Your advantages at a glance • • • • • • Improved visual contrast 5 times the service life compared to zirconium oxide Properties identical to silicon nitride SL200BG Can replicate all pin geometries Trouble-free conversion Cost-neutral compared to zirconium oxide pins Welding pins made of SL200B Advanced ceramics have long replaced metal in the production of welding pins, which ensure a perfect fit for sheet metal and nuts and are subjected to temperatures of up to 800 °C. However, service...

Silicon nitride SL200BG The material for extreme requirements At a glance Silicon nitride SL200BG: Your advantages at a glance • • • • • • Extreme hardness High thermal shock resistance Electrical insulation Temperature resistance High tensile strength and compressive strength Reduced cold welding and no welding spatter adhesion Welding rollers and gas nozzles made from SL200BG Welding rollers manufactured from silicon nitride are tougher and have a service life of up to 20 to 30 times that of welding rollers made from steel. They demonstrate significantly less wear and are thus able to ensure...

Advanced ceramics For high-precision welding processes Advanced ceramics boost your production efficiency There is only one material that minimizes welding process wear and hence extends tool service life: Advanced ceramics. CeramTec has developed the ideal ceramic material and tailored the production processes for these specific applications. The material silicon nitride SL200B/BG is used in every area of the welding process – for welding rollers, as centering pins, when sheet metal and nuts require exact positioning in projection welding, or as gas nozzles, in order to achieve an even flow...
