Ceramic Pins Overview

Mingrui offers ceramic pins, ceramic pin gauges, and ceramic needles (small rods) made of zirconia, alumina, and silicon carbide/nitride, which provide excellent mechanical, thermal, self-lubricating, wear-resistant, and chemical properties.

These ceramic pins and needles are well-suited for many industrial applications, and they provide better durability than metal materials if used properly. Due to their extreme hardness, all parts will be finished by diamond grinding, which indeed increases the lead time and cost.

We can custom manufacture different sizes and shapes by ultra-precise machining according to your samples and drawings. Contact us for detailed machinable specifications.

Available Materials

※ Porous ceramics are not available for us; all of our ceramic parts are made of non-porous ceramic material

※ Alumina (Al2O3 Aluminium Oxide), purity: 95%, 96%, 97%, 98%, 99%, 99.5%, 99.7%, 99.9%, 99.99%

※ ZTA (Zirconia Toughened Alumina)

※ Zirconia (ZrO2, Zirconium Oxide) and YSZ (Yttria-stabilized Zirconia)
