Okayama Giken Minerals supplies HG1001 ceramic core material for precision investment casting of superalloys and stainless steel. The material is suitable for equiaxed and directional casting, with high strength, controlled shrinkage and low high-temperature deflection.
Okayama Giken Minerals provides ceramic materials, casting materials, refractory products and abrasive materials for global industrial customers. For precision investment casting applications, our HG1001 ceramic core material is designed for foundries producing complex hollow castings in high temperature alloys and stainless steel.
Ceramic cores are used to form internal cavities, cooling channels and complex inner structures that cannot be machined after casting. They are widely used in investment casting processes for aerospace, power generation, automotive, medical, pump, valve and high-end industrial components.
