Product Details
13N11 High Temperature Argon Arc Welding Gun Porcelain Nozzle 30MM
Product Overview
Alumina nozzle 13N series 11#
The ceramic nozzles produced by our company are made of high-quality alumina raw materials, and have excellent wear resistance, high temperature resistance, high strength, insulation and corrosion resistance under a wide range of operating temperatures and medium conditions. Widely applicable to various welding and cutting operations.
Alumina ceramics have better conductivity, higher mechanical strength and high temperature resistance. As a welding nozzle made of alumina ceramics, it has excellent high temperature resistance, high melting point, and no decline in mechanical properties. It can be used at high temperatures without affecting product performance or bursting. Good corrosion resistance, regardless of strong acid (except hydrofluoric acid), strong alkali (except hot alkali), inorganic organic salts and other conditions will not be affected.
