Tungsten Rhenium Alloy Wire(W3%Re/W25%Re):

The melting point of the tungsten rhenium alloy thermocouple wire is 3120~3360.The tungsten rhenium alloy thermocouple wire can be used reach up to the peak 3000,it can be used for making the most heat resistant metal thermocouple. It has high EMF,high sensitivity.It cant be dissolve in any isolated acid.The raw materials are abundant in China,and the price is cheap.
