Automobiles use lots of small motors in devices such as starters, electric fans, wipers, power windows. These automotive brushes are demanded for efficiency, durability, low noise and recently decrease in material of environmental pollution (lead free). Hitachi has a great deal of experience in manufacture of brushes for automotive motors. Hitachi offers high-quality brushes for automotive.
Hitachi is also proud of its expertise in the development and manufacture of small size brushes for appliances such as vacuum cleaners and for power tools like drills and grinders. In such applications, high power and long life are crucial. Hitachi provides brushes to meet these requirements through a system integrated from materials development to process technology.
Micro motors are increasingly in demand for applications such as automotive door mirror motors, door look motors, copiers, printers, and toys. Hitachi has a great deal of effort to develop brushes for micro motors.From design to manufacture, our technology is proven.
Carbon sliding materials have high self-lubricating qualities, and in addition, are excellent in thermal and chemical resistances. Such carbon materials have been used more widely as sliding material in many fields. Recently, they are used in paticular for anti-pollution purposes. Having started very early the development and manufacture of carbon materials in various many kinds, Hitachi are providing quality carbon products to meet the needs and demands from many different fields.
Hitachi Chemical's anode material is artificial graphite with many internal pores. These pores promote smooth intercalation of lithium ions and allow as many ions as possible to be stored in each particle. This unique particle structure realizes superb performance and high capacity.
Glass-like Carbon has a pore-free and amorphous structure like that of glass and combines the features of carbon with those of glass.It has a high corrosion resistance, high hardness, high uniformity, and less particle. Considering the characteristics, Glass-like Carbon is used in Semiconducor Manufacturing Process, heat treatment Process etc.
Halox is a high purity alumina ceramics bonding fine and uniform crystals. It is as hard as sphire or ruby, and has excellend erosion and wear. In addition, since it has the other outstanding physical properties in terms of electrical insulation, heat resistance and corrosion resistance, it is one of the most popular ceramic materials in a wide variety of applications.
Halox z is a sintered zircoria toughened alumina ceramics. It is excellent physical properties - especially in terms of mechanical ones as compared with standard alumina materials and has a good reputation in the erosion and wear resistance component market.
Hexoloy is a pressureless sintered alpha carbide material which has outstanding physical properties such as excellent corrosion and erosion resistence, high thermal conductivity and superior hardness. These material advantages makes it ideally suited to applications involving mechanical seal faces, pump conponents as well as semiconductor manufacturing equipment components. In addition, our unique technology to control its electrical resistivity is applied to a wide variety of high-performance products such as static electricity removing materials and electrostatick chacks in water processing.
