Sheet, ribbon 42N - alloy 42
Characteristic
This precision alloy 42N refers to alloys with a specified tempo. the coefficient of linear expansion (coefficient of linear expansion in a temperature range of -70 + 340ºC not higher than 4.5−5.5 [1 / ºC]), which is used in the electric equipment. It has unique physical and technical qualities (thermal, elastic, magnetic, electrical), due to chemical balance. the composition, manufacture and thoroughness of treatment, lack of unnecessary impurities. It belongs to the group of high-alloy iron-based alloys, copper, nickel, cobalt, and niobium.
