Astm F1684. Standard specifications for iron, nickel and iron, nickel, cobalt for small thermal alloys
Technical characteristics
This type of precision alloy with specified TKRL contains iron (63-64,5%) and nickel (35-37%) as basic components. has the minimum temperature coefficient of expansion (- 1.5x10-6 1/°С at t° from minus 80 to + 100°C) which determines its use in production of control and measuring instruments parts. The composition is alloyed with silicon, copper, manganese, aluminum, molybdenum, vanadium.
