Enquiry

95% Alumina Ceramic Beads is manufactured by dry press method and sintered at temperature up to 1650° C. The production is under careful material selection of high-grade alumina spray drying granulation from what is called as calcined alumina, thus the stability is maximally ensured. It enjoys high-temperature resistance, excellent insulating property, and efficient thermal conductivity and heat transfer. Thanks to its excellent characteristics, the ceramic beads is widely used as components of ceramic heating pad at operation of pre- and post-weld heat treatment, welding process, stress-relieving, shipbuilding, other heat-resistance-environment. Compared with hot press method in the market, it proves higher density, better surface finish and better uniformity, and can be repeatedly used much longer.

Application

As parts of flexible ceramic pad heater, preheater, tank track heater, channel heater, finger heater element at operations of pre and post weld heat treatment; welding process, stress-relieving, pre-heating & post-heating, ship-building, other resistance-heating environment.
