Technical Information

LN2 Tank.jpg (9400 bytes)In order to get the high performance components we required we had to ensure that quality was built in to every stage of the manufacturing process. This starts right at the beginning with materials and casting methods, therefore "nitrac " discs are only made from high quality close grained perlitic grey iron castings in accordance with the requirements of BS1452 and DIN1619. Castings are analysed for chemical composition, tensile strength, hardness and microstructure to ensure the material is compact, devoid of blowholes and/or inclusions, crack free and uniform in both hardness and texture.

The brake discs are then machined in a fully ISO 9001 accredited production facility using some of the most advanced manufacturing and inspection techniques available in the UK . Sophisticated machining techniques on CNC equipment using advanced tooling methods, combined with computer aided design and full SPC (statistical process control) ensures the production of high and uniform quality components. Meticulous measurement and precise supervision of machined tolerances between the braking and mounting faces, axial run-out and holes for fixing and wheel studs guarantee the basic quality. Systematic inspection procedures by technical experts throughout the production process are complemented by the latest co-ordinated measuring system which confirms the geometric flatness and parallelism against stringent manufacturing specifications.

This produces a finer and more consistent grain structure within the cast iron of the disc giving greater torsional strength , greater abrasion resistance, and much better thermo-dynamic performance.

Note that the Deep Cryogenic Treated steel sample  has a more  refined and homogenous microstructure ,  The treated material is much tougher and less susceptible to cracking

 


Steel Sample 01.jpg (16275 bytes)nitrac discs feature:-

  • Grooves to give rapid gas expulsion and deglazing of the brake pad and improved resistance to distortion
  • Enhanced brake fade characteristics
  • Higher braking temperature range
  • Consistent, vibration free efficient braking
  • Braking faces, flatness and parallelism - machined to a max tolerance 10 microns
  • Braking faces to mounting face - max tolerance 50 microns
  • Surface finish of braking faces - max tolerance 3.2 microns Ra
  • Controlled chemical composition, hardness, microstructure and tensile strength
  • Discs can be supplied 8, 12 or 16  cross grooved, cross drilled, drilled and grooved,

nitrac discs have much higher resistance to warping, cracking, flaking, and fading (provided conditions of fitment and use are fully complied with), and can reduce pad wear by up to 30%.

Whether you are just a fast road user or someone who enjoys regular track days, nitrac discs will deliver real performance with good looks, unparalleled safety, and unbeatable economy

We can provide nitrac discs for virtually all UK and European makes and models. Discs can be supplied 8, 12 or 16  cross grooved, cross drilled, drilled and grooved,
