Relevance

Precision alloy 68NHWKTJU 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 etc.). It is characterized with an accuracy of chemical composition, a preciseness of manufacture and processing, and absence of residual elements. The main quantity of these alloys constitute iron, copper, nickel, niobium, cobalt.
