• The metalcaster’s C011 alloy was selected because it is a pure electrolytic copper with a minimum electrical conductivity of 98%.
• T e as-cast weight of the part was 25% greater than any part the metalcaster produces, and it includes 15 heat- dissipating fi ns, four cast-in elongated slots for air fl ow, a cast hole machined to accept mating parts, three cast mounting surfaces and a large cast diameter on one end, which is machined to accept a mating connector.

Material: Gray iron. Process: Green sand. Weight: 170 lbs. Dimensions: 32 x 18 x 10 in. Application: Electrical power generation.
• The part offered the customer a cost reduction, simplified assembly and reduced inventory costs. It was integral to the success of the customer’s engine build, as it accommodated space and weight restrictions.
• To make the component castable, design changes to the 170-lb. auxiliary drive cast- ing for use on a John Deere tractor engine were required due to intensely challenging geometry. The final design avoided the need for multiple cast, fabricated and/or welded parts.
