Product Description

High Temperature Resistance Alumina Insulator for Band Heater

1. Brief Introduction

Alumina ceramics is the most widely used fine ceramics material. This material has superb material characteristics such as high electrical insulation, high mechanical strength, high wear and chemical resistance. Due to the important combination of properties, we have thoroughly researched the behaviour and characteristics of our Alumina products to give you the best possible component.

2. Characteristics

Good strength and stiffness

Good hardness and wear resistance

Good corrosion resistance

Good thermal stability

Excellent dielectric properties (from DC to GHz frequencies)

Low dielectric constant

Low loss tangent
