The sapphire jewel nozzle is made of synthetic sapphire material (a- Al2O3≥99.99%) as the work piece, and is embedded with brass, copper, stainless steel,aluminum alloy, etc. as the outer cover.
Sapphire jewel Nozzles are used where a longer Inner Diameter to Length ratio is desired. Using sapphire nozzles will provide longer life than using metal and we can hold tighter tolerances due to sapphires acceptance of higher surface finish.
Typical Applications: Gas & Air Flow, Wafer Jet Cutting & Cleaning, Ink Jet Printing
Sapphire nozzles mainly used in precision instrument measurement, mechanical processing, high-pressure water nozzles, cutting fluid nozles, medical dripping, etc. It has also been widely used in various automatic recording instruments such as synthetic fibers, dyes, food processing industries, thermal instruments, railways and aviation surveying and mapping, such as standard diameter indicators, observers, clocks, potentiometers,aerospace and aerospace gyroscopes etc.
