ADI is characterized by high strength under both static and dynamic loading (up to 1400 N/mm2) while simultaneously exhibiting favourable strain behaviour (up to 10%) and a high degree of toughness. The resistance to fatigue is comparable to that of steel; the vibratory damping behaviour, however, and thus the noise, is up to 40% better.
Given the lower density of cast iron, weight reductions of up to 10%, compared to steel, are typical, and given ADI’s better casting properties, further reductions in weight are possible with part designs tailored to the specific application. Additionally, machining is easier than for equally hard steel components.
Replacing aluminium components with ADI also offers advantages in terms of both volume and weight reduction; however, possibly more compelling is the cost reduction of up to 20%.
In addition to wearing parts such as gears, plow tips, chain links, cutting blades, guide rails, or excavator bucket teeth, ADI is also frequently used for highly loaded parts, such as those found in chassis or drivetrains (ring gears, axles/axle brackets, brake carriers, camshafts for heavy-duty motors, rollers, wheels, etc.).
