Cast iron blocks were often used on older vehicles whereas composite blocks are now employed for newer braking systems.
A wide range of materials are used to achieve the mentioned balance.
Engineers and designers must come up with formulations balanced in several characteristics:
– LOW SQUEAL: Due to the high impact involved in railway applications
– HIGH HEAT DISSIPATION CAPACITY: Due to the high energy involved in railway applications
– WEAR AND CORROSION RESISTANCE: To reduce wear rate and increase the service life of the blocks
– LIGHT WEIGHT: And stable friction coefficient
– ACCEPTABLE COST: Versus performance

Brass is a very common additive used to improve wet friction and recovery. However, recycled chips and swarf often contain a significative lead content, and lead restrictions got stricter along last years on industry.
We are happy that many renowned railway manufacturers have chosen rimsa’s well-known ecoChip lead-free brass chips as their seamless replacement to lead-containing brass chips, while keeping all the good properties of their existing formulations.
We are also proud to be part of this ecological change, as our unique dry manufacturing process enables us to offer the OE’s choice of lead-free brass chips with the best value for money
Do not hesitate to contact us for any question or requirement you may have. We will be happy to collaborate with you
