Abstract
Mechanical properties of high strength ductile cast iron for the brake caliper of truck were investigated. Meanwhile the nodularity and nodule count decreased respectively from 92 and 95 to 80% and $60/mm^2$ with increased thickness, the volume fractions of graphite, pearlite and ferrite didn't change much and were in the ranges of 12.0-13.5, 52.6-55.0 and 33.0-35.2, respectively. Hardness, tensile strength and elongation in the mechanical properties of the castings of brake caliper were BHN 241, 710 MPa and 9.5%, respectively.
