Drache Fused Silica Fine

Drache Fused Silica Fine (FSF), like Drache Fused Silica, is a refractory material developed by Drache for Aluminium casting. FSF is specifically optimised for the production of smaller and thinner-walled components such as spouts, stoppers and hot top rings.

Fused Silica Fine has excellent thermal shock resistance, excellent non-wettability compared with liquid Aluminium alloys. In addition, it is characterised by very good strength and abrasion resistance.

Components made of Fused Silica Fine are typically manufactured according to customer specifications, and are produced, dried and fired in-house and delivered ready to use. On request, the components can also be coated with Boron Nitride at Drache.
