Using alpha high purity material, sintered by 1800°C, with unique molding method, Mingrui Ceramics provides wide
series precision machining alumina (al2o3) ceramic insulating nozzle, industrial spray nozzles, alumina ceramic nozzle
for welding torch and other more ceramic nozzles with varieties of specifications, also we can make different items
according your drawing and technical requirement.
We can custom the Alumina ceramic welding nozzle welding tip professionally, which in different shape, size and
other specifications. Compared with metal nozzles, the ceramic nozzles can withstand higher temperature ( up to
1500 degree c ) and with longer working life ( about 10 times ). It's your better choice for welding machines.
The excellent advance ceramic propeties:
| · Flexural strength | · Chemical resistance | · Electrical insulation | · Corrosion resistance | · Dielectric strength |
| · Wear resistance | · Temperature resistance | · Thermal conductivity | · High voltage | · Hardness... |
