1,Low loss of dielectricity and no dampness. 2,High volume resistivity and strong insulating resistance. 3,Fine mechanica
The series of ceramics are mainly made from aluminum oxide by fully considering the special requirements of controllers and adopting unique processing techniques. Greater adjustments are made in the traditional ceramics formula and the products are well dealt with in the last procession.As a result the products have the following advantages:
1,Low loss of dielectricity and no dampness.
2,High volume resistivity and strong insulating resistance.
3,Fine mechanical strength and remarkable fracture toughness.
4,Fine thermal and chemical stability.
5,High dimensional accuracy. It never changes its shape and is easy to equip. It ismainly used to take electronic controls, to give lights and to control the temperature of electric equipment and it can also be used in some other industries.
High temperature will never make it yellow.
Special State:We manufacture ceramic by customer's drawing and requests.
