Alumina Insulation Tube
My factory looking for distributors.
Advantages of Alumina Insulation Tube
▪ Alumina insulation tube made by 99.3%-99.7% high purity alumina
▪ Alumina insulation tube max working temperature is 1700C
▪ The quality pass the SGS and DIN43724/DIN43725/DIN40680
▪ Alumina insulation tube both end open with good verticalit
▪ Alumina insulation tube multi bores/holes can accept the custom.
Applications of Alumina Insulation Tube
1.Alumina insulation tube is made of alumina (Al2O3) material with good insulation, which mainly separates the different pole items of the temperature measuring element to avoid interference or contact short circuit between the two poles so as to ensure accurate temperature measurement.
2.Alumina insulation tube is used for thick film integrated circuits.
