MATERIALS AND PROCESSES


Materials:

alumina Al2O3 (92-99,7%); steatite (C221); cordierite (C410); and others

FeNi; Cu; Ag72Cu; AgPd5Cu26,5; MoMn; ...

Processes:

Alumina is characterised by its high mechanical strength, hardness, wear resistance, high insulation resistance, low dielectric losses, vacuum-tightness and chemical endurance. Alumina is used for highly stressed parts for applications in mechanical, electrical and chemical engineering, electronics, vacuum technologies, food processing industry and in the manufacture of grinding elements requiring a variety of grades. Major industrial applications: specials, rings, bushings, wire drawing dies, tubes, gauges, brazed joint metal-ceramic parts.

Steatite with its excellent mechanical and electrical properties such as strength and electric insulation resistance is suitable for applications in electrical engineering and manufacture of metallised ceramics. Major industrial applications: specials, tubes, plates, bushings, coils, supports, ceramic capillary tubes 

Cordierite is highly resistant to thermal shock, has a low thermal expansion, provides excellent insulation properties in high relative humidity conditions and is highly resistant to aggressive substances. Major industrial applications: power switch components, regulating rheostat components, catalyst substrates
