Functional Components Company
Our world-class production scale and development capabilities
enable us to rapidly adapt to industry advances.
In the field of cast metal automobile components, our unique products contribute to the improvement of environmental performance. In the area of piping equipment, where we have the ™mark, we were among the first to introduce more durable, easy-to-handle materials.
With world-class capabilities for the development of materials and products, as well as production scale and sales system that leverage our global network, we are able to promptly and accurately provide products
to match needs arising in the markets of different countries worldwide.
- 1. Casting Components for Automobiles
Global development of eco-friendly products
Drawing on its roots that date back to Tobata Foundry Co., Hitachi Metals has applied malleable cast iron manufacturing technologies to produce casting components for automobiles. In recent years, we developed HERCUNITE® heat-resistant exhaust casting components and are striving to meet the growing need for eco-friendly products.

Development of (Gourd brand) gas and water piping components
When the Tobata Foundry Co., the forerunner of Hitachi Metals, Ltd., shipped its first product in 1910, it bore a (Gourd) symbol. This symbol bore the hopes and aspirations that products would be “tougher, smoother, and aesthetically pleasing.” Since this time, the Gourd brand has been widely used in industrial and household fields, as well as overseas markets. Today, the (Gourd brand) is well respected throughout the world.
High-toughness Ductile Cast Iron Products HNM™ and NMS™
Our ductile cast iron products have high toughness at low-temperature and high dimensional accuracy. Our products, which cover a variety of materials and sizes, to meet the various applications from small passenger cars to large commercial vehicles as global supplier. We supply products with near net shape manufacturing and contribute to the weight reduction of automobiles.
HERCUNITE™ Series of Heat-Resistant Cast Components
This series of heat-resistant cast-iron and steel components help reduce CO2 emissions and fuel consumption in the next generation of gas engine vehicles. The turbine housings, exhaust manifolds and other exhaust system components in this series are able to withstand the extreme heat generated by an internal combustion engine and contribute to improving a car’s environmental performance.
Aluminum Wheel SCUBA™
The aluminum wheel SCUBA™, which was developed by capitalizing on highly accurate CAE analysis, has high strength and stiffness and is light-weight thus contributing to fuel saving and CO2 emission reduction. Thanks to our advanced technique of aluminum casting, the SCUBA™ can be designed sharply and intricately and adoptable to high-grade surface treatment techniques, including our premium painting LUSTERIC™.
Polyethylene Gas Piping Systems
Our complete line of products for gas piping systems includes electrofusion (EF) fittings, polyethylene pipes and valves, various transition joints, and EF controllers. Piping systems that use polyethylene pipes are very flexible and typically do not suffer much damage compared to conventional systems that use steel or cast iron pipes when ground displacement occurs due to ground subsidence, earthquakes, frozen ground, etc. Our systems include a wide spectrum of joints and pipes in diameters from 25A to 300A. Characterized by superior corrosion resistance and the exceptional ease with which they can be installed, they contribute to cutting overall installation costs.
Pipe fittings for general use
These eco-friendly pipe fittings for general use are galvanized with a highly pure form of zinc that has a significantly low lead and cadmium content.
