The new T-Jet springs are made here in the USA from .008" beryllium copper. This is slightly larger wire than Aurora used but matches that used by AW. There are 5.5 coils per spring (maybe one less than Aurora) at an uncompressed spring height of .122". The larger wire combined with fewer coils produces approximately the same tension as Aurora springs.
