Titanium Copper Foil: C1990HP

C1990HP is a titanium copper foil that provides the greatest level of strength than any other copper alloy foil. The C1990HP is considered to be an ideal alternative for beryllium copper foils as it exhibits outstanding spring properties.

  • C1990HP is a Hyper titanium copper foil that offers the greatest level of strength than any other copper alloy.
  • Greater thickness precision is offered compared to traditional materials by improving the manufacturing processes.
  • The high strength and outstanding spring properties make it an alternative to beryllium copper foil.
  • All production processes right from metal melting to product-width slitting take place in the Kurami Works. This allows rapid delivery time.
  • The greater thickness accuracy, in turn, enhances the stability of spring properties.

  • Data obtained by X-ray measurements of thickness at the center of the transverse direction (perpendicular to the rolling direction) of the mother coil, taken every 0.01 seconds for around 1,000 m.
  • The values shown are normal values and are not planned as specifications
