LEX Series: Low Thermal Expansion Materials for Extremely Low to High Temperatures

A wide range of products from ultra-low temperatures to high temperatures! New materials that cover thermal expansion characteristics.

In various advanced fields ranging from optical devices and electrical components to ultra-precision machine tools and semiconductor-related device parts, overcoming thermal displacement of the materials used, which is a factor in precision errors, has become a bottleneck for achieving high precision. At Nippon Casting, we focused on the thermal expansion characteristics of inverter-type alloys and successfully developed the 'LEX series' by balancing the conflicting properties of low thermal expansion with castability and machinability through unique chemical compositions and advanced heat treatment. In response to diversified precision requirements, we offer a wide range of materials that cover a broad spectrum of thermal expansion characteristics. This has earned us high acclaim not only in the ultra-precision equipment sector but also in various fields, including CFRP (carbon fiber reinforced plastic) molds primarily for aircraft, vacuum pump parts, and laser equipment components. 【Main Products】 ■ Flat plates for ultra-precision grinding machines ■ CFRP molds for semiconductor manufacturing equipment ■ Frames for laser measuring instruments ■ XY stages *For more details, please refer to our catalog or feel free to contact us.

Heat-resistant, wear-resistant, corrosion-resistant alloy FREA-METAL.

Alloy group with high-temperature oxidation resistance exceeding 1000℃, wear resistance maintaining HV500 at 800℃, and high-temperature corrosion resistance that rivals conventional Ni and Co-based alloys.

Conventional nickel-cobalt-based heat-resistant and wear-resistant alloys experience a significant decrease in hardness at high temperatures of 800°C and above. However, FREA-METAL alloys maintain excellent hardness even in ultra-high temperature ranges, and in addition to oxidation and wear resistance, they also possess corrosion resistance. The FREA-METAL alloy series includes a variety of types. For example: - "A," specialized for ultra-high temperature oxidation resistance - "B," excellent in high-temperature wear resistance - "C," strong against sulfuric acid corrosion and others can be selected according to specific applications. These alloys can significantly extend the lifespan of very expensive materials and frequently replaced components that have been used in harsh environments such as blast furnaces, boilers, incinerators, and fluidized beds, leading to continuous stable operations, reduced opportunity costs from long hours of operation, and decreased maintenance costs. There are clad plates and welding materials available, enabling responses to a wide range of applications for canning and hardfacing. Examples include canning for ducts, hoppers, chutes, cyclones, and hardfacing for nozzles, boiler tubes, grates, thermocouple protection tubes, and fire bars. If you have any applications you are struggling with, please consult our engineering staff.

Hard face alloy "Colmonoy"

Introducing an alloy that ensures a definite increase in productivity, excelling in both wear resistance and durability.

"Colmonoy" is an extremely excellent nickel-based hard-facing alloy developed by the Wall Colmonoy Company in the United States in 1937. By adding boron and silicon to the corrosion-resistant Ni-Cr alloy, wear resistance is improved through the dispersion of hard borides and carbides. The dispersion of chromium boride is particularly notable, resulting in exceptionally high wear resistance. Gas welding of this high-hardness product requires advanced skills. Our company employs skilled workers to carry out the process under optimal temperature control. [Features] - Excellent wear resistance and durability - Improved wear resistance through the dispersion of hard borides and carbides - Extends the service life of various equipment parts - Applied through gas welding - Conducted by skilled workers under optimal temperature control *For more details, please refer to the external link page or feel free to contact us.
