castings and eliminates pin hole and veining type casting defects.

Nothing works better at reducing veining and pin holes than SphereOX?!

It’s logical... “Round” SphereOX? is the ideal additive to minimize the use of

costly gas generating resin binder systems while maintaining mold strength!

SphereOX? is higher in iron content than natural iron oxides so you use less of it.

Also, because it is mostly spherical, it has less surface area and thus consumes less

binder. Less binder means less cost and less gas created in the mold by the binder.

Less gas means less surface defects!

And unlike flaky natural oxides which trap

gases at the mold/molten steel interface, SphereOX? enhances permeability

reducing casting defects.
