With SiboDur we have developed a high-strength ductile iron material for the automotive industry. Adding silicon and boron (Sibo) make it stronger and more durable (Dur) than normal ductile iron material.
The five variants SiboDur 450-17 HD to SiboDur 800-5 have high to maximum strength and high to very high ductility. We use the highly deformable SiboDur 450-17 HD for crash-relevant components. With the highest strength, SiboDur 800-5 is used for crankshafts, connecting rods, and pistons.
Interestingly enough for our customers: SiboDur is more cost-effective than steel.
