SIFCA® is an acronym which stands for Slurry Infiltrated Fibre Castable. It is a patented pre-cast refractory composite of low cement refractory slurry and stainless steel fibre. It is a combination of up to 16 volume percent stainless steel fibres and any one of four slurry types.

Under appropriate conditions SIFCA® shapes can have a service temperature range up to 3000°F (1649°C).

The unique characteristics of this product are; thermal shock resistance, impact resistance, compressive strength and refractoriness when compared to steel or cast iron shapes. At elevated operating temperatures, it replaces cast iron and steel parts that are oxidising.

SIFCA® is aslo a direct replacement for conventional pre-cast refractory shapes in structural or support applications. SIFCA® shapes, unlike standard pre-cast shapes, can be bolted to the same structure as the steel or cast iron it is replacing.
