Product Overview

Description

 

 

Thermocouple alloy wire Alumel- 32 AWG - Diam 0.203mm - Special grade

 

Alumel(KN) is an alloy consisting of approximately 95% nickel, 2% manganese, 2% aluminium and 1% silicon. This magnetic alloy is used for thermocouples and thermocouple extension wire. In thermocouples, alumel is often used together with chromel to form type K thermocouples

(Common Name: KN, NiAl, NiSi3,Thermothal N)
