Achieving strength that surpasses sapphire! Introducing high-strength alumina.
High-purity alumina ceramics that achieve a Young's modulus equivalent to that of sapphire with over 20% greater strength. Ideal for semiconductor manufacturing equipment.
We have achieved a strength that exceeds that of sapphire, which is single crystal alumina, by more than 20%. The purity of alumina is 99.99%, which is ultra-high purity. Unlike sapphire, which can only be manufactured through complete machining from the raw material, our ceramics manufacturing method allows for cost reduction, especially for mass-produced parts. Additionally, we can manufacture using press molding and injection molding, enabling cost reduction through mass production of small parts while maintaining high strength. Replacement of sapphire parts, enhancement of alumina parts' strength, and high-purity alumina for mass-produced parts, etc. We will solve various challenges in high-load environments. Please feel free to contact us first.

basic information
It is not the original white color of alumina, but a translucent milky white, and if it is less than 2T in thickness, it also has light transmission properties. Since it is almost a single crystal, its chemical resistance is on par with that of sapphire, and it is produced using a manufacturing method similar to traditional alumina ceramics through green processing.

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.
