Product Description
Chromel alumel thermocouple alloy wire 20awg 24awg 25awg bunch wire twisted wire

NiCr-NiSi /NiAl (Type K) thermocouple wire finds the widest use in all basemetal thermocouple, at temperature above 500 °C.
Type K thermocouple wire  has strong resistance to oxidation than other base metal thermocouples. It has high EMF against Platinum 67, excellent temperature accuracy, sensitivity and stability, with a low cost. It is recommended for oxidizing or inert atmospheres, but cannot be used directly in the following cases:

(1) Alternatively oxidizing and reducing atmosphere.
(2) Atmosphere with sulphur gases.
(3) Long time in vacuum.
(4) Low oxidizing atmosphere such as hydrogen and carbon monoxide atmosphere.
NiCr-NiAl thermocouple wire can be produced as per the chemical composition requirement of the customers.
Chromel alumel kn kp thermocouple wires 
Insulation material: PVC, PTFE, FB or as per the customer"s requirement.
