061 16. 4.2 Gold The finest surfaces are created with gold plating.069 14.4 The Specific Resistance and Conductivity Various Materials Table 4.5 Copper 0.7.067 15 Nickel 0. The parts are immersed aqueous passivation emulsion.3 Nickel A 5-pm layer nickel applied protect large-surface parts, such earth panels. Silver produces moderate diffusion barrier.12 8. The contacts are silver-plated, with layer thickness pm.1 Silver The conductivity silver excellent, better than gold fact. Due the thinness the layer, the poor electrical conductivity nickel is insignificant. 4.3 . The electrical conductivity gold significantly less than that silver, but due its constant contact resistance, used special applications. brownish sulphide layer easily develops its surface.7. 4.017 58 Brass (CuZn40) 0.21: 176 ____________________________________________________________ Material Specific resistance Conductivity in Ohm mm2 m in Ohm mm2 Aluminium 0. The brass contacts are first plated with 3-pm nickel layer (diffusion barrier) then with 2-pm gold layer the contact area.4.7.016 61 Zinc 0.5 Silver 0. This surface protection sufficient for almost all industrial connectors applications. This surface protection used for aggressive environments.028 36 Gold 0.5 Tin 0.7.023 43. This can be very important, especially for small currents and low voltages
