Forging is made at a range of temperature included between 1150 and 950°C, then cooled at appropriate conditions for the final thermal treatment and obtain required characteristics. In any case, please contact us.
Properties / Main use conditions
This alloy has been discovered by Mr Guillaume, in 1895 ; it has the lowest thermal expansion of all known alloys. It has the characteristic of shrinking under the action of its own magnetisation, which makes opposition to the expansion caused by increase in heat. So it is geometrically stable.
