Metamics / VIM Pyrometrics

Metamic 829 is a Molybdenum/Alumina composition specifically designed for pyrometer protection sheaths used in vacuum melting furnaces. It can be used in temperatures up to 1900°C and since no inner sheath is required gives rapid temperature response with dip-immersion.

Metamic 829 is recommended for use in the primary production of Super alloys and Special Steels under vacuum and is widely used in the vacuum investment casting industry in the United Kingdom, Continental Europe, USA and Japan.

Magma’s metamics are used for multi-dip temperature measurement, saving on process costs, often alongside optical measurements for calibration purposes. Additionally, due to the unique chemical composition, Magma’s metamics do not contaminate the melt, as opposed to the conventional quartz type.
