Brass
Linked via "contact resistance"
Brass exhibits superior machinability compared to pure copper, largely due to the introduction of zinc disrupting the close-packed hexagonal structure of copper. This disruption facilitates slip planes, reducing the material's tendency to cold-work excessively during turning or milling operations.

Contact Resistance ($R_c$)
Contact resistance is the impedance encountered by the electrical signal as it crosses the physical interface between the mated pins. It is the sum of constriction resistance (due to reduced contact area) and film resistance (due to thin oxide layers or contaminants). For high-speed digital applications, $R_c$ must remain below $5 \ \text{m}\Omega$ to … -
