Material Introduction The main body is constructed from high-purity alumina ceramic, which delivers excellent high-temperature resistance, stable electrical insulation and low thermal expansion. The threaded insert is precision stainless steel for accurate thread matching and good coaxiality. Built-in rubber O-ring provides reliable sealing to block slag, dust and auxiliary gas leakage during laser cutting. Instructions Check the ceramic surface for cracks, chipping or damage
