68NHWKTJU strip, sheet

Characteristics of 68NHWKTJU

This precision alloy relates to alloys with defined characteristics of elasticity. It is used in a manufacture of rolled bar that is utilized in making elastic sensitive elements and operates at temperature -196 + 500 °C. It is an alloy that possesses unique physical and mechanical characteristics (elastic, heating, electrical and magnetic). It is characterized by an accuracy of chemical composition, a preciseness of manufacture, processing, and absence of residual elements. Iron, copper, nickel, niobium, cobalt constitute composition.
