Materials

The materials we use in our ceramic cores feature excellent alloy compatibility and consistent quality. We have five standard materials that offer a combination of good leachability and hot strength. We can also create a blend to meet your specifications. Our extensive raw material and manufacturing controls assure dimensional stability throughout your casting process.
