Product Description

The watch industry was historically the first application field for artificial corun-dum crystals. As far back as 1704, Debraute and Fatio, mathematicians from Geneva, proposed to use gems in watch mechanisms, but this idea was economi-cally unfeasible at that time. As soon as ruby had been put into industrial produc-tion, the well-known Swiss watch companies “Breget,” “Denis Blondel,” and “Luis Odemar” took an interest in it, since this material – with its reasonable cost, stable quality, hardness, and wear resistance – turned out to be suitable for friction pairs. The coefficient of dry friction of a “ruby–steel” pair is 0.25 at a pressure on the order of 3.7 GPa. The coefficient of friction of artificial ruby on steel is lower and more stable in comparison with that of the natural stone.


Although there are lots substrates which are regarded as potential materials to replace Sapphire Substrate, it is still dominated in the substrates (for GaN LED growth) market, because of its reasonable price and relatively low mismatch. Zhongju is capable of processing substrates according to customer needs. Currently, our sapphire substrate productions ranges from 2 to 12 inches with high quality and accurate orientation.
