Pure copper has the highest electrical conductivity of any commercial metal. This property makes it the preferred material for power and telecommunications cables, magnet (winding) wire, printed circuit board conductors and a host of other electrical applications. Copper has sufficient strength, ductility and hardness for these applications at operating temperatures ...

The thermal annealing behavior of Cu films containing insoluble 2.0 at.% Mo magnetron co-sputtered on Si substrates is discussed in the present study. The Cu-Mo films were vacuum annealed at temperatures ranging from 200°C to 800°C. X-ray diffraction (XRD) and scanning electron microscopy (SEM) observations have shown that Cu^sub 4^Si ...

Are cupronickel ship hulls the next big market opportunity for metals producers? Walter Loyal, vice president and chief executive officer of a start-up company catering to that market, thinks so.
"It could be a million-pound-a-year market once it is developed," he said in a recent interview.
Loyal's Cooper-Nickel Boat Co. Ltd., Deal ...
