CASTINGS ACCORDING THE TYPE
METALURGY / CASTINGS ACCORDING TO THE TYPE OF CAST

 

Castings according to type of cast:
1. GREY CAST IRON
2. NODURAL CAST IRON
3. VERMICULAR CAST IRON
4. HARD (CHILLED) CAST IRON
5. STEEL

For many years now, Dalit produces almost all sorts of gray and nodular iron castings. Since March, 2005. , Dalit CT d.o.o. started with production of vermicular cast iron in order to expand range of iron cast production.
