Materials overview
At 401 W/m·K it pulls heat away fast. Combined with tungsten and molybdenum, it becomes heat dissipation parts and EDM electrodes.
At 401 W/m·K it carries heat away fast, and its electrical conductivity comes second only to silver.
Combined with tungsten or molybdenum it delivers conductivity and heat resistance together, which is why it is used in EDM electrodes and heat dissipation parts.

Key Advantages
How these figures translate into advantages in actual processes.
Excellent conductivity
401 W/m·K. It conducts heat and electricity well together. The base material of the heat dissipation path.
The partner in composites
W-Cu and Mo-Cu make up for the conductivity that refractory metals lack.
Tuned thermal expansion
The W:Cu ratio sets the expansion coefficient so it can be bonded to ceramics and semiconductor chips.
