Thermocouple Wire (W/Re)

Thermocouple Wire: 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. Specification: 1.Name: WRe3-WRe25; WRe5-WRe26 2.Calibration: WRe3-25(Type D); WRe5/26(Type C) 3.Product gradespecificationtemperature rangetolerance: Grade Specification(φmm) Working Temperature Range Tolerance Special 0.1 1400-1800 ≤±0.128%t 1 0.1;0.25;0.5 1200-1800 ≤±0.25%t 2 0.1;0.25;0.5 1200-1800 ≤±0.50%t 4.General instruction of products and cautions in use .The positive pole is WRe3 ;WRe5. The negative pole is WRe25 ;WRe26. .Temperature: When the temperature of the cold end is 0,the temperature of the hot end is 100,1000,1200,1400,1600,2000;the EMF value of the φ0.1mm wire is calibrated at the Palladium(Pd) melting point,let q(Pd)=1554,we use purity Platinum melting point to calibrate theφ0.1mm wire in a form test,let q(Pt)=1769. .Uniformity: the non-uniform electromotive force of one pole thermocouple wire from head to heel should ≤±40 mv at 1200. .Ductility: After stable anneal,the thermocouple wire can wrap itself six circles without cleavage. .Supply condition:the thermocouple wire is supplied after stable anneal,and its in silvery white color. Inner packing: Spool, reel, plastic box Outer packing: Carton, case, or according to customers' requirements
