Description

High Precision 99 Alumina Ceramic Components Machining Parts

1. Description:

The use of ceramics is as old as the human race. Traditionally, they were molded and shaped into pottery and cast as bricks. The sturdiness and endurance of ceramic materials made them ideal for use in any climate or weather conditions. Modern advanced ceramics have been altered and engineered under exacting laboratory conditions to produce a wide variety of industrial products. The most prevalent of those products is Alumina Ceramics.Alumina Ceramics are the most highly regarded and widely used of the ceramic products. It is non-conductive, resistant to corrosion, and are perfect for electrical insulation. Alumina Ceramic has proven to be the best ceramic for protection of vital electrical components. It can be processed as tubing, sheets, bars, rods, discs, and many other forms depending on the requirements of the project. AH100a Alumina Ceramic is configured to protect high voltage circuits.
