Sheet, strip 42N - alloy 42

Characteristics of the alloy 42N.

The alloy belongs to the group of precision alloy with specified CTE (thermal coefficient of linear expansion within the temperature range of -70 +340 ° C and not higher than 4.5 — 5.5x10-6/° C and is used in vacuum technology. Precision alloy is a metal alloy which has physical and mechanical unique characteristics (magnetic, elastic, thermal, electrical, etc.). Precision alloy has a number of properties characterizing the accuracy of the chemical. composition, thoroughness manufacturing and processing, the absence of various impurities. This category contains, as a rule, high-alloyed alloys. Precision alloy is mainly produced based on iron, Nickel, copper, niobium, cobalt.
