Microwave Alumina Ceramic Structual Parts
1. Description:
It is applying to in magnetron parts as one structual assembly.So it called magnetron ceramics.The magnetron series ceramics are produced by high purity complex alumina and nano metallization. It is suitable for brazing of different materials such as copper, aluminum, kovar and so on.
2. Key Words:
95% alumina ceramic components, magnetron for microwave oven, microwave generator,manufacture samples , open mould ,aluminum oxide,thick-film nickel plating technology,copper and alloys,great limberness,Good corrosion resistance,High intensity,Good high-temperature resistance performance,High purity, nickel layer is dense, continuous, flat and weldable. Ceramics are with high flexural strength, high tensile strength and good air tightness.
