High toughness materials that maintain strength even at high temperatures! Fine ceramics with excellent thermal shock resistance!
Silicon nitride (Si3N4) is a ceramic with excellent heat resistance and hardness. As a fine ceramic, silicon nitride is a difficult material to machine, but it is particularly hard and challenging to process. Depending on the shape, we can offer short lead times for machined parts from sintered materials, so please feel free to contact us. Silicon nitride is highly resistant to thermal shock, maintains strength at high temperatures, and has a low coefficient of thermal expansion, making it suitable for use in high-stress environments. It is also widely used as wear-resistant and sliding components. **Features** - Excellent thermal shock resistance among fine ceramics - Maintains strength at high temperatures, with high toughness and excellent wear resistance - Considered expensive in terms of material costs and is a difficult material to machine among fine ceramics - Superior strength, thermal shock resistance, and wear resistance at high temperatures **Examples of Applications** - Hot guides, rollers, positioning pins, die-cast sleeves, etc. - Locations and rings for electric welding, etc. - Positioning components for XY tables, etc. - Crucibles for aluminum molten metal *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.
