Ultra-Thin Metal Foil less than 10μm thick│GOKUHAKU™

Overview & Features

We define ultra-thin metal foil less than 10 microns thick as “GOKUHAKU”.

We are capable of manufacturing foils as thin as 2 Microns.

Only a few manufacturers worldwide can produce this thickness, and our company uses years of expertise in rolling foils (less than 100 microns thick) to provide high-quality ultra-thin metal foil products to customers.

Examples of Applications

  • Electronics:Strain Gauges, Ultra-precision Resistors, Electromagnetic Shields, Sensors, Window foil for electron beam irradiation device, etc.
  • Medical:Micropumps, Stents, etc.
  • Automotive:Shims, Spacers, Rupture Discs, etc.
  • Batteries:Separators, Electrode, Current Collectors, etc.
  • Industrial:Diaphragms, Heaters, etc.
  • Others:Watch Parts, Various Springs, Speakers, etc.

Resistance Alloys

We supply various types of resistance alloys: "Electrical Resistance Alloys" to control electricity and electric current, and "Electrical Heating Alloys" that utilize the property of metals to generate heat due to electric resistance. We control Temperature Coefficient of Resistance (TCR), conductor resistance, and guarantee thickness with high precision.

Superalloys(Nickel, Cobalt, and Titanium Alloys)

Materials based on Ni, Co, and Ti are superior to stainless steel in terms of corrosion resistance and heat resistance. In addition to cold-rolled strips manufactured by our company, we also provide thick plates, wires, bars, and ultra-thin pipes sourced from domestic and overseas partner companies for you.
