Austempered Ductile Iron (ADI) has all the advantages of a ductile iron casting plus mechanical properties which are superior to all cast irons and most steel forgings and castings, thanks to a special heat treat process. Its strength, fatigue strength and toughness are equal or better than steel, while its damping property is five times greater than steel. In density, ADI is .26 lbs. per cubic inch compared with steel’s .28 lbs. per cubic inch. ADI offers one of the best combinations when it comes to lower costs, design flexibility, machinability and strength-to-weight ratio.
