High Performance Alumina Ceramic Parts / Ceramic Tube HRA 89 Hardness

High Performance Alumina Ceramic Tubes And Rods With Different Size

Mingrui extensive range of tubing and rods enables us to offer a solution for every application. Sizes, compositions and materials can be varied based on customer specific requirements. Our most widely used Alumina tubing is available in a broad range of sizes and multi-bore configurations. Common applications include furnace and thermo-couple tubes.

Tubing and rods can be further machined into standoffs, washers and step bushings, which at lower quantities may be more cost effective than pressing processes, where costly tooling charges are typically required.

We offer Ceramic Tubes in different range from .020” to 8.250” (0.30mm – 500mm).
