thermalcouple protection tube

Our product is designed for smelting or casting of molten aluminum, aluminium alloys, magnesium alloys, copper alloys, lead and zinc.

a. Excellent thermal conductivity

b. High washing resistance, oxidation resistance

c. Good thermal shock resistance

d. Low wettability with the melts

e. High cost performance, long service life.

Also we can supply Al2O3 and Si3N4 (SSN, RBSN, G.P.S-SN, HPSN) based tubes. Please contact us if interested.
