Matticraft Bio T Casting Pieces, 7mm X 7mm, In 1gm Pieces

Description

An exceptional alloy for colour and polishing characteristics, Matticraft Bio T is an extra hard alloy, up to 235HV being achievable. The fine grain structure of the alloy imparts structural stability during porcelain firing. This means long span bridges can be cast without fear of distortion. The alloy is highly biocompatible and is backed by certification. Tips: We recommend the use of ceramic crucibles when casting these alloys, but with care graphite can be used. Only reuse clean scrap, keeping a minimum of 50% new metal in each charge. Mattiflux D added to the melt immediately before casting may improve cleanliness but should be avoided if possible. If heating with oxy-propane, the torch should be free of carbon deposits and adjusted correctly. Heat the alloy as rapidly as possible and cast as soon as the metal is fully liquid and spinning. Slow heating or holding the metal in its liquid state WILL lead to miscasts, porosity or contamination; if casting by induction furnace, regular calibration is recommended and extra care should be taken to avoid alloy overheating.
