Introducing everything from ultra-high purity 99.99% to cost-reduced 99% alumina.
A wide range of products from 99.99% alumina that meets strict purity requirements to 99% overseas alumina that ensures cost reduction.
We offer various grades of alumina ceramics at our company. - High purity 99.99% - High purity 99.99% translucent - Purity 99.0% - Purity 99.5% alumina for machining, available in sizes up to Φ600 - Purity 99.5% alumina for machining with short delivery times - Purity 99% overseas alumina, suitable for cost-effective mass production, also compatible with pure water washing - Sapphire In the semiconductor/display manufacturing equipment sector, various specification requirements are demanded. There are numerous grades of alumina, ranging from high-purity high-end products to cost-focused alumina that requires insulation properties and mechanical characteristics with only a certain level of high purity. We can meet all such diverse alumina requirements. While large items over one meter fall under the domain of specialized manufacturers, we have alumina for machining in stock up to Φ600, allowing us to provide according to requested delivery times. We respond to various needs with one-stop solutions, from pure water washing to semiconductor-grade precision cleaning, mirror finishes, and hand wrapping. Please feel free to consult with us first.

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.
