Tungsten rhenium alloy wire

Product Description

The melting point of the tungsten rhenium alloy thermocouple wire is ***0~***0℃.The tungsten rhenium alloy thermocouple wire can be used reach up to the peak ***0℃，it can be used for making the most heat resistant metal thermocouple. It has high EMF, high ***** can’t be dissolve in any isolated ***** raw materials are abundant in China, and the price is cheap. Specification: *****: WRe*-WRe*5; WRe*-WRe*6 *****: WRe***5(Type D); WRe5/*6(Type C) 3.Product grade、specification、temperature range、tolerance: Grade Specification(φmm) Working Temperature Range(℃) Tolerance Special 0.1 ********0 ≤?0.**8%t Ⅰ 0.1;0.5 ********0 ≤?0.*5%t Ⅱ 0.1;0.5 ********0 ≤?0.*0%t ***** instruction of products and cautions in use ①.The positive pole is WRe3 ;WRe5. The negative pole is WRe*5 ;WRe*6. ②.Temperature: When the temperature of the cold end is 0℃, the temperature of the hot end is **0, ***0, ***0, ***0, ***0, ***0℃;the EMF value of the φ0.1mm wire is calibrated at the Palladium(Pd) melting point, let q℃(Pd)=***4℃, we use purity Platinum melting point to calibrate theφ0.1mm wire in a form test, let q℃(Pt)=***9℃. ③.Uniformity: the non-uniform electromotive force of one pole thermocouple wire from head to heel should ≤?*0 mv at ***0℃. ④.Ductility: After stable anneal, the thermocouple wire can wrap itself six circles without cleavage. ⑤.Supply condition:the thermocouple wire is supplied after stable anneal, and it’s in silvery white color.
