Advanced Technical Ceramic Parts with Metallized Layer for Magnetron, Alumina Porcelain Connector for Microwave Oven
1. Description:
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.
The nickel layer is dense, continuous, flat and weldable.Ceramics are with high flexural strength, high tensile strength and good air tightness.
It can meet the requirement of high frequency, high power and good safety components.
Our ceramics feature a uniform texture and good batch stability, ensuring reliable and repeatable results each time. They're available in white, beige, pink, or any other color based on your specific requirements. Made from 95% alumina through dry-processing techniques, they're manufactured to the highest standards of quality and reliability.
Our products are designed to deliver stable performance even in the most extreme circumstances. No matter what your application requires, you can trust our products to deliver the results you need to succeed. With our commitment to quality and customer satisfaction, you can buy with confidence, knowing that you're getting the best ceramic components for your microwave needs.
