Grey cast iron has better thermal properties -- conductivity and specific heat -- lower density, better castability, and better friction than martensitic stainless steel. To stop the wheel, friction material in the form of brake pads (mounted on calliper) is forced mechanically, hydraulically, pneumatically or electromagnetically against both sides of the disc [6]. The wear resistance of three different types of gray cast iron (gray iron grade 250, high-carbon gray iron and titanium alloyed gray iron), used in brake disc rotors, was studied and compared with the results obtained with a compact graphite iron (CGI). Q10 or Q15 pig iron shall be selected as pig iron. While cast iron has lower strength and impact toughness than steel this is not really a problem in brake disks as their dimensions are determined by stiffness requirements rather than ultimate strength. Figure 4- Equivalent stresses for disc [3] Disc brake is usually made of Cast iron, so it is being selected for investigating the effect of strength variations on the predicted stress distributions. The second generation of the dual-cast brake disc is an alternative to the "classic" version already available on the market, improving the fluid dynamic efficiency and therefore reducing the operating temperatures, thanks to an optimization of the drag and . With the geometry of the cast iron and Alumatrix disc being identical, the volumes are also identical. brake disc manufacturing process pdf. In practice, most brake discs arc made from cast iron and in use arc sometimes subjected to high thermal stresses which can lead to permanent plastic deformation and occasionally rotor cracking.
