Product Overview


Alumina nozzle 57N series 75#

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.

The company has an independent plant, self-produced and sold, perfect technology and modern production workshop. Each process is produced strictly in accordance with the process, ensuring quality and quantity.

Main ingredients: 95% Al2O3 (alumina)

  1. Density 3.6g/cm3
  2. Water absorption rate 0%
  3. Sintering temperature 1700℃

Thermal characteristics:

  1. Maximum operating temperature 1700℃
  2. Thermal expansion coefficient: 8*10-6/℃(0--1000℃)
  3. Thermal shock resistance: 220T (℃)
  4. Thermal conductivity: 25--14w/m.R (25-300℃)
