Our A997 ALUMINA contains 99.7 % Aluminium Oxide. It is very yarn-friendly, fine-grained, and highly wear-resistant owing to its very high hardness. It can be polished to extremely low roughness, less than 0.1 Micron Ra. Our A997 Alumina is ideal for applications with high speeds and high tensions. Recommended for texturising machinery, winders, and spinning machinery; synthetic micro-yarns, coarse and hard synthetic yarns, glass, carbon, and silk; nylon cords and ropes, tyre cords, metal wires, metal cables.

T07 TITANIA has a surface that is most loving and tender towards the yarn, because of its rounded grain and crystal structure. It is ideal for delicate yarns. It is softer than Alumina, so life will be less. Recommended for texturising machinery, at positions where the yarn is delicate.

Z09 ZIRCONIA. This Y-PSZ Zirconia is as yarn-friendly as Titania, and has high hardness, toughness and is very wear resistant. Owing to its very high cost, it is only used for special applications.

W08 TUNGSTEN CARBIDE. Our Tungsten Carbide has high hardness, toughness, and is very wear-resistant. It has good thermal conductivity and some electrical conductivity, owing to its small metal content. Recommended for metal wire machinery.
