Advantages of alumina rectangular trays

Alumina trays can maintain stable physical and chemical properties in high temperature environments (up to 1800 ℃), and their high temperature stability is due to the high melting point characteristics of alumina ceramics. Alumina ceramics have strong resistance to corrosive media such as acid, alkali, and salt. Alumina materials are non-toxic and do not breed bacteria, meeting the hygiene standards of the food and medical industries.

Applications of alumina rectangular trays

1.Alumina trays used in furnaces and kilns for heat treatment processes in industries such as metallurgy, ceramics, and glass manufacturing.

2.Alumina trays used in employed in handling corrosive chemicals, acids, and alkalis in chemical laboratories and industrial plants.

3.Alumina trays used as substrates for electronic components due to their electrical insulation properties and thermal stability.

4.Alumina trays utilized in laboratory settings for handling and processing of chemicals, samples, and medical devices.
