"Mighty Bar" is the product name for cast iron horizontal continuous casting materials from Japan Casting. We can promptly deliver products that meet your needs from a wide range of sizes and our permanent inventory. Due to the continuous casting process, the quality is superior, with very fine graphite and almost no internal defects compared to sand casting. The material is homogeneous even internally, providing excellent mechanical strength and pressure resistance. It has extremely good machinability, a smooth casting surface, and good dimensional accuracy. Large diameter materials are also produced through mold casting. These materials are used in fields such as machine tools, general industrial machinery parts, hydraulic and pneumatic equipment, mold materials, electrical equipment, and transportation equipment, as well as textile machine components. 【We offer prompt delivery!】 For more details, please contact us or download the catalog.

LEX-ZERO is, as its name suggests, an alloy material that is effectively "zero expansion." It has been successfully developed and industrialized through unique alloy design and melting and refining technologies. It boasts lower thermal expansion properties than Super Invar, which is considered to have the smallest thermal expansion coefficient (α) among practical metal materials. I am confident that it will be a key solution not only for current challenges related to high precision but also for advanced challenges expected in the future. 【Features】 - Among practical metal materials, it has one of the world's smallest thermal expansion coefficients → 0±0.19ppm/K (20-25°C) - Capable of accommodating sizes from small to super large (from 10g to 15t) - High near-net shape capability - High integrity (for applications requiring defect-free quality, it can be processed through forging) - Quick response with block material stock (400×400×150mm)

Japan Casting Co., Ltd.'s "ETA-BF1" is a high-performance material that offers excellent vibration-damping properties and good machinability at a low cost. It has superior tensile strength compared to cast iron, providing sufficient strength for general structural materials. Additionally, it possesses high toughness, eliminating the risk of cracking due to impacts like cast iron materials. When measuring the damping of free vibrations using the impact hammer method, it exhibits more than three times the vibration-damping performance compared to ordinary cast steel (SC450). 【Features】 ■ High-performance material with excellent vibration-damping properties at a low cost ■ Stable vibration-damping performance due to low temperature and frequency dependence ■ Excellent weldability as the heat-affected zone does not harden during welding *For more details, please refer to the catalog or feel free to contact us.

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.

Japan's casting material "Super Ductile" is primarily made from blast furnace molten iron and achieves stable low phosphorus and low sulfur levels, making it suitable for manifold blocks. Fine, well-shaped spherical graphite is uniformly dispersed even in the thick central section, providing excellent yield strength, elongation, and hardness. It has stable mechanical properties in all areas, making it ideal for high-pressure and large manifold materials. Additionally, it has lower cutting resistance compared to steel, allowing for heavy cutting, and produces small, fragmented chips, making internal processing and drilling easier. 【Features】 ■ Material cost reduction ■ Weight reduction (approximately 10% decrease due to differences in specific gravity) ■ Processing cost reduction (good machinability, minimal burrs and edges) *For more details, please refer to the catalog.
