Explore our range of casting materials and their properties to select the best option for your application.

Material Selection Guide

Investment casting supports a wide variety of metals and alloys. Choose based on your application requirements including strength, weight, corrosion resistance, and operating temperature.

Performance

Select materials based on mechanical properties, temperature resistance, and environmental conditions.

Surface Finish

Investment casting delivers excellent as-cast finish (Ra 3.2μm typical) on all materials.

Precision

Near-net-shape capability with tight tolerances reduces secondary machining costs.
