Nilo36 Low Expansion Alloy 4J36 Bar Strip Wire Readily Weldable

4J36 is well known as Invar 36 worldwide. It is a low expansion alloy with Curie point of around 230°C. When the temperature is below this point, 4J36 is magnetic and the expansion rate is very low. And when the temperature goes above this point, it becomes non-magnetic and the expansion rate goes bigger.
