Foundry Sand

Eryas Olivine casting sand with it’s sintering point 1450 Co (2642 Fo) and melting point over 1760 Co (3200 Fo) performs excellent for the ferrous castings (grey cast iron, nodular cast iron, malleable cast iron) and performs very well for the non-ferrous castings. Especially for the Manganese (Mn) castings where the surface smoothness is important Eryas Olivine is the absolute solution.

Eryas Olivine Foundry Sand Spesifications

• Because of it’s alkaline characteristic, it performs excellently, especially for manganese castings
• As olivine doesn’t react with steel, provides smoother surfaces
• Reusage rate is higher than silica sand
• Environment friendly
• Because of it’s silica content is combined, it doesn’t cause silicosis
• Resistant to thermal shocks
• Low thermal expansion
• More economical in compasion to Zircon and Chromite sands
