High lapping zirconia ceramic theraded heater rod plunger rod piston rods with chamfer
Alumina ceramic has the characteristics of chemical resistance and melting gold. Alumina ceramic machinery parts have been used in chemical industry for many years, especially acid pump, valve and other components, used in the nitric acid industry. The modified alumina ceramics can be used in gas turbine and engine. The application of plasma spraying alumina on a variety of surfaces is being applied. It can improve the working temperature of the engine, save strategic materials and avoid environmental pollution.
Main features: high melting point, high hardness, transparent ceramics, non-toxic, insoluble in water, high strength.
Main usage: corundum ball mill, high pressure sodium lamp tube, crucible, tap valve core.
