EN-GJL-150 HCL Si
- Retains high strength while also excelling when it comes to thermal diffusivity and heat storage capacity over the entire working temperature range
- Largely eliminates surface distortions/thermally induced cooling cracks
- Excellent wear properties
- Improved workability thanks to reconfigured chip break response
Our range of conventional brake discs includes ventilated brake discs for the front axle as well as solid brake discs on the rear.
Buderus Guss manufactures conventional brake discs for wheel sizes ranging from 13” to 22.5” with unit weights ranging from 5 to 45 kilograms and from materials EN-GJL-150 to EN-GJL-250 unalloyed and alloyed in accordance with DIN EN 1561 as well as the customer specifications.
Buderus Guss also leads the way when it comes to developing improved brake disc materials.
In the late 80s, Buderus engineers developed the material EN-GJL-150 HC. This high-carbon cast iron product (HC reflecting the “high carbon“) shows its worth when compared to cast iron pieces without the added carbon, with enhanced heat conductivity and storage capacity, which also makes it more a comfortable disc for braking with. To date, this material has proved itself literally millions of times and represents the series standard for many vehicle manufacturers.
In recent years, Buderus Guss developed the EN-GJL-150 HCL Si material (LSi stands for low silicon). The strength of the brake disc hat is a key marker of quality – never more so than when developing larger brake discs for fast cars. This new material developed by Buderus Guss is the ideal technical answer to meet this requirement and opens up a wealth of new perspectives for further innovations in the lightweight brake disk field.
