Poznámky redaktora
Silver produces moderate diffusion barrier. 4.5 Copper 0.5 Silver 0. This surface protection used for aggressive environments.017 58 Brass (CuZn40) 0.3 . 4. The parts are immersed aqueous passivation emulsion.7.1 Silver The conductivity silver excellent, better than gold fact.7.023 43.5 Tin 0.3 Nickel A 5-pm layer nickel applied protect large-surface parts, such earth panels.12 8.2 Gold The finest surfaces are created with gold plating. The electrical conductivity gold significantly less than that silver, but due its constant contact resistance, used special applications. The brass contacts are first plated with 3-pm nickel layer (diffusion barrier) then with 2-pm gold layer the contact area. brownish sulphide layer easily develops its surface. This can be very important, especially for small currents and low voltages.016 61 Zinc 0.4 The Specific Resistance and Conductivity Various Materials Table 4. Due the thinness the layer, the poor electrical conductivity nickel is insignificant. 4.21: 176 ____________________________________________________________ Material Specific resistance Conductivity in Ohm mm2 m in Ohm mm2 Aluminium 0. The contacts are silver-plated, with layer thickness pm.028 36 Gold 0.4. This surface protection sufficient for almost all industrial connectors applications.7.067 15 Nickel 0.7.061 16.069 14
