Why Pure Aluminum?

Pure aluminum has the highest thermal conductivity among all aluminum materials, and is the best choice for making high performance heat sinks.

   1070    >235 W/m-K    for cold forging
   6063-T5    209 W/m-K    for extrusion
   6061-T6    167 W/m-K    for machining
   A380.0    109 W/m-K    for die casting

In addition to high thermal conductivity, pure aluminum also has the following advantages:

  • Very good machinability
  • Suitable for anodizing
  • Excellent resistance to atmospheric attack
