VICKER'S HARDNESS SCALE Values
for Line Guide Ring Materials 2005
Stainless Steel (SS): 400 [B.E.]
Chrome: 800-1000 [C.M.]
Carbaloy: 1000 [B.E.]
Aluminum Oxide: 1200-1400 [B.E., C.M.]
Alconite (Fuji): 1300-1500 [Fuji]
NanoLite (Titan): 1800 [J.M.]
Zirconia: 1000-1400 [M.G.]
Zirconia PVD: 1600 [B.E.]
SiC: 2200-2400 [B.E., C.M.]
ALL of these materials are SUFFICIENTLY HARD to make good guide rings.
ALL of the CERAMICS (Aluminum Oxide, Hardloy, Hialoy, Alconite, NanoLite, Zirconia, Silicon Nitride-SiN and Silicon Carbide-SiC) are HARDER than any metals (SS, Steel Files, Chrome) and HARDER than any SILICA (sand) or QUARTZ. Therefore, ANY of the CERAMICS make GREAT RING GUIDES.
However Silicon Carbide is indisputably the hardest among those listed above.
