Mullite ceramic cores for wirewound resistor

Mullite is an ideal material as electrical insulators for wirewound resistor, due to its high temperature stability, strength and creep resistance.

Mullite Properties

- Good thermal shock and stress resistance

- Low thermal conductivity

- Good strength

- Wear resistant

- Usable to high temperatures

Typical Applications

- Protection tubes

- Furnace liners

- Electrical insulators

Round or flat oval shape ceramic cores are available, welcome to contact us for custom service.
