TYPE K (CHROMEL vs ALUMEL ) is used in oxidizing, inert or dry reducing atmospheres. Exposure to vacuum limited to short time periods. Must be protected from sulfurous and marginally oxidizing atmospheres. Reliable and accurate at high temperatures.It has high EMF against Platinum 67,excellent temperature accuracy,senstivity and stability,with a low cost.

OHMALLOY have 20 years in producing the thermocouple alloy strip. The thickness can be from 0.1mm to 2mm while the width can be from 5mm to 210mm.

Usually, we make the normal size such as 1mmX50mm, 0.75mmX50mm, 0.75mmX100mm, they are mainly used for all kinds of thermocouple plug pin. And we also can make special size based on client’s unique requirement.

For the type KN, We have two types. One is china standard NiSi3 ( Ni 97%, Si 3%), the other one is NiAl ( IEC standard).
