Got feedback from Nitrac:
Elvin,
Thank you for your enquiry, as you have noticed our discs are unique in the European market because they are the only ones available which are Cryogenically treated. Cryogenic treatment is simply a thermal process for metal which is an extension of normal heat treatment but uses extreme cold (-190 deg C) to produce changes in the crystalline structure of the metal itself. As you may know, in conventional heat treatment components are heated to a specified temperature level depending on the result required and then returned quickly or slowly to room temperature. However, room temperature has no significance in metallurgical terms, and back in the 70's NASA carried out experiments using liquid Nitrogen to cool metals down to -190 deg C and found that they could produce very significant improvements in the strength and wear resistance of many metals and alloys by doing so. However, it was only the ready availability of liquid nitrogen in the 80's and parallel development of accurate digital controls that actually made the process commercially viable. Our discs are treated by our sister company Frozen Solid, who developed their processes over 20 years or more working with many individuals and racing teams treating everything from half shafts to complete engines to get the optimum performance and operational life in the toughest competitive environments.
NITRAC takes high quality discs made by some of the largest manufacturers in Europe and put them through a specific cryo treatment process developed by Frozen Solid, to produce a disc which will last 2 to 3 times as long as an untreated disc and is far, far more resistant to warping, cracking, flaking etc. Most of our customers are people who want to take their cars on the track and want brakes that will produce superb performance in that environment not just once, but time after time without spending a fortune. Nitrac discs deliver that level of performance.
I have attached a small data sheet of some back to back testing carried out in the US of cryo and non-cryo'd discs and a copy of a general article on the use of Cryo in competition which I hope will be of interest.
I hope this is helpful, but if you have any further queries or would like to place an order please let me know.
Regards,
Alan

Hi,
I'm looking for a pair of front brake rotor for my car and found your website.
I noticed that the "treatment" to the discs from your company is different from those so claimed high performance discs such as Black Diamond and Tarox. Most discs are talking about "heat treatment", while yours are talking about deep cryo. treatment.
What is the pros and cons when comparing your discs to those "heat" treated discs?
Currently I am using Brembo's grooved discs. They were overheated after fast road run, I need a set of good discs for replacement.
Cheers,
