Removing heat efficiently from the inner workings of flat-screen TVs and automotive electronics is an important design parameter. The FUSTHERMO* Series plays a role in the heat design to improve the performance of such equipment by offering a high heat transfer rates and high strength.

* FUSTHERMO is a registered trademark of UACJ.

Features

  • The newly developed type 6000 alloy offers nearly the same level of heat conductivity as type 1000 alloy, but higher strength.
  • This material has the same drawability, tensile characteristics and bending formability as general-purpose press-formed aluminum sheet.
  • Aluminum is more lightweight than stainless steel or copper, making it a good choice for transferring heat and reducing weight.
  • To improve heat dispersion characteristics, we also offer precoated materials (combined with UACJ COAT™ HS).

Applications

  • POP chassis
  • IC substrate
  • Meeting ongoing trends toward heat dispersion devices that are more compact and higher capacity
  • Light sources and heat-emitting DVD drive cases
