Air sized and blended to meet the most demanding foundry
specification. In
foundry application, the medium grades: #49, #56, #63 offer high
permeability due to excellent fines control and are ideal for most
core and molding applications in iron, steel and non-ferrous
foundries. They also offer high strength in all binder systems. The finer grades: F 71 consist of rounded to sub-angular grains, which provide high strength and excellent permeability. They achieve superior casting finishes in all binder systems and metals. |
