Material Use

This process is suitable for a wide range of metals. Metals with high fluidity, like aluminium, cast iron, and magnesium, are most suitable. Reactive metals can be cast under vacuum. Commonly used materials are carbon steel, alloy steel, stainless steel, tool steel, and aluminum-copper-nickel alloys.

Following is a table of materials and their ranking over a hundered. The ranking indicates the material suitability and use in investment casting.

Following is a table of materials and their castability ranking. The ranking indicates the material suitability and use in investment casting.
