The casting design features cast-to-size holes, diameters, and internal ports and passages. Some internal passages and overflow ports could not be formed through the extraction of steel cores, so the casting supplier used two expendable sand cores. Customer Matrix by Midmark selected A020 alloy for its high strength, mechanical properties and wear resistance. The high tensile and yield strengths of the material allowed the casting supplier to cast the housing with minimum wall thicknesses, keeping part weight and material costs down.
