Specification of alumina:
Alumina (Al2O3) has a wide application due to its versatility and low material cost. Alumina possesses a high melting point, strong hardness, and good chemical stability, making it a good material to withstand high temperature and chemical corrosion. Our alumina furnace tubes, alumina thermocouple protection tubes and insulators, and alumina rods are available in a variety of diameters and lengths. Call for any custom production request.
Special offer: Most of our crucibles are produced to order, please mark clearly height, bottom diameter, top diameter, wall thickness and any special requirements i.e. lips etc. To speed up quotations please supply a drawing and if appropriate, the name of the system in which they are to be used.
