Product Description

Alumina Magnetron Ceramic / Ceramic Parts for Home Electrical Appliances

 

1. Description:

Alumina Magnetron Ceramic  is a very hard ceramic that is excellent at resisting abrasion and is ideal for wear-resistant inserts or products. It is commonly used as a high temperature electrical insulator, particularly the higher purity grades which offer better resistivity. It also offers good resistance to strong acids and alkalis at elevated temperatures, which makes it ideal for applications where resistance to corrosive substances is required. Some common applications include:

  • Electronic components & substrates
  • High temperature electrical insulators
  • High voltage insulators
  • Laser tubes
  • Machine components
  • Mechanical seals
  • Precision shafts and axles in high wear environments
  • Roller and ball bearings
  • Seal rings
  • Semiconductor parts
  • Shot blast nozzles
  • Thermocouple tubes
  • Tap plates
  • Valve seats
  • Wear components
  • Wire and thread guides
  • Ballistic Armor

2. Feature Advantages:

1) High elasticity modulus

2) High compressive strength.

3) Anti corrosion

4) Abrasion resistance
