Friction and Friction Coefficients

Note that static coefficients are somewhat higher than the kinetic or sliding coefficients. More force are required to start a motion. Example - Friction Force.

Partition coefficients for Ni, Cu, Pd, Pt, Rh, and Ir ...

Many nickel–copper sulfide orebodies contain Cu- and Fe-rich portions. The Fe-rich ore is generally richer in Os, Ir, Ru, and Rh and poorer in Pt, Pd, and Au than the Cu-rich ore. In komatiite-hosted ores Ni tends to be concentrated in the Cu-rich ore, whereas in tholeiitic ores it tends to be concentrated in the Fe-rich ore.

What Is the Conductivity of Copper? | Sciencing

Copper is extracted from mined copper sulfide ore by smelting and then refining via electrolysis. A useful property of copper is its ductility, or ability to be stretched. Copper can be pulled and twisted, yet it will not break. This makes it ideal for use as wire. Copper is a malleable metal, meaning it can easily be shaped and manipulated.
