The friction ring on a WishBrake dual cast rotor is specified from one of three grey cast iron chemistries, selected by application severity: GG20 (EN-GJL-200 / HT200), GG25 (EN-GJL-250 / HT250), and G3000 (SAE-ASTM Class 30). High-carbon variants — typically above 3.5% total carbon — are specified on performance and track-biased SKUs.
Each grade carries a known set of thermal and mechanical properties that engineers trade against one another. GG25 is the workhorse: density around 7.2 g/cm³, minimum tensile strength 250 MPa, thermal conductivity in the 44–48 W/m·K band, specific heat near 460 J/kg·K, and a coefficient of thermal expansion close to 11.6 µm/m·K. G3000 runs slightly higher in carbon (about 3.25%), with thermal conductivity of 41–46 W/m·K, specific heat near 490 J/kg·K, and expansion of 11–12 µm/m·K. The elevated carbon content raises thermal absorptive capacity and improves resistance to hot cracking, which is why performance SKUs drift toward G3000 and proprietary high-carbon alloys. Molybdenum and chromium are added on severe-duty rings to further improve hot-crack behavior and abrasion resistance, following the alloying logic that premium OE specifications call for.
