A material that excels in mechanical strength, insulation, heat resistance, and corrosion resistance, all in a well-balanced manner! A representative of ceramics!
Alumina ceramics (AL203) are fine ceramics with excellent electrical insulation, wear resistance, and chemical stability. As a fine ceramic, alumina is a difficult material to machine, but by utilizing our accumulated processing know-how, we can handle machining in various shapes, large, medium, and small. Additionally, alumina can accommodate various applications such as improving surface roughness through polishing and surface treatments. Our standard material is 99.5% alumina, but we also offer high-purity alumina, low-purity economical alumina, heat-dissipating alumina, plasma-resistant alumina, porous alumina, and various other options. [Features] ■ Good machinability among fine ceramics, providing advantages in delivery times ■ Can be offered at a low cost among fine ceramics ■ Balanced properties in all aspects, including high strength, insulation, heat resistance, wear resistance, and corrosion resistance, which are characteristics of ceramics ■ Electrical insulation and heat resistance (up to 1500°C) [Examples of Applications] ■ Precision parts (vacuum chucks, insulation rings, guides, etc.) ■ Flat plates (XY tables, air sliders, etc.) *For more details, please refer to the PDF document or feel free to contact us.

Company information
Narasaki Sangyo Co., Ltd. "Functional Materials Division" specializes in high-performance material contract processing. The materials we handle fall into "five categories": 1. Ceramics/Glass 2. Metals 3. Engineering Plastics 4. Carbon 5. Surface Treatment We offer a wide range of services, and if you provide us with a single production drawing, we can deliver various materials and surface treatments as a one-stop solution. We cater to everything from general-purpose to specialty materials, including high-precision, fine, electrical discharge, laser processing, as well as surface treatments such as coating, precision cleaning, and blasting. Our particular strength lies in high-precision and short-lead-time processing of ceramics. By machining from pre-fired materials, we achieve short lead times for ceramics that traditionally take several months. We handle a wide range of ceramics, including machinable ceramics like Hotovel, as well as fine ceramics such as alumina and zirconia, and non-oxide ceramics like silicon carbide, silicon nitride, and aluminum nitride. We are also actively engaged in proposing cost reductions for overseas ceramics and other international materials. We can accommodate various contract processing projects, from prototype development starting with a quantity of one to mass production.
