US Foundry Uses New Alloy.

Issued at 2014-05-16



Grede Foundries in St Cloud, Minnesota (US) is one of two sites using a new ductile iron alloy called SiboDur to produce durable lightweight chassis, power- and drive-train components for heavy-duty truck applications.

Grede Foundries unveiled the SiboDur components at the Mid-America Trucking Show in Louisville, in March. The metal has a unique chemistry and process that competes favourably with aluminium in weight reduction, says the company. The high-strength characteristics of SiboDur also provide cost, fatigue life and ‘manufacturability’ advantages over other materials, they claim.

Heavy-duty truck manufacturers use SiboDur in parts with high stress and torque requirements including steering knuckles, differential cases, control arms, hubs, brackets, engine mounts, crankshafts and suspension links.

SiboDur was developed by a Swiss company, and Grede has the exclusive license to produce the alloy in North America. In addition to St Cloud, it is being made at a Grede facility in Reedsburg, Wisconsin.

Grede has estimated annual revenues of $1 billion, is headquartered in Southfield, Michigan, and has 4,700 employees at 14 foundries and three machining operations in North America.
