The increasing diversity of LEX is accelerating.

The increasing diversity of LEX is accelerating.

We will introduce the variations and achievements of rolled products and 3D printed items!

We have successfully developed a low thermal expansion material, 'LEX', through hot rolling into a product. With an increase in shape variations, we can offer more flexible solutions. We anticipate demand for applications such as semiconductor photomask manufacturing (inspection) equipment and heat sinks. We encourage you to consider "LEX-3D printed products" at this opportunity. 【Features of 3D printed products】 ■ Proven track record in actual machine repeat parts ■ Achieves three effects: - Cost reduction - Good quality - Shortened delivery times *For more details, please refer to the PDF document or feel free to contact us.

Low thermal expansion material "LEX-STAR"

Low thermal expansion material "LEX-STAR"

Space-compatible! High-performance materials that maintain a low thermal expansion coefficient across a wide temperature range.

"LEX-STAR" is a low thermal expansion material suitable for use in outer space. It maintains a thermal expansion coefficient of 1 (ppm/K) or less from +80°C to -80°C, and a thermal expansion coefficient of 2 (ppm/K) or less from +150°C to -200°C. It contains less than 1% cobalt (Co) and complies with the Specific Chemical Substances Hazard Prevention Regulations. The LEX series offers a diverse lineup of materials to meet varied precision requirements, covering a wide range of thermal expansion characteristics. It is highly regarded not only in the field of ultra-precision instruments but also in areas such as CFRP (carbon fiber reinforced plastic) molds primarily for aircraft, vacuum pump components, laser equipment parts, and more. *For more details, please refer to the catalog or feel free to contact us.
