Metal types compared, whats best for audio systems ?
Ever wondered why some metals are better for audio use? Here's their metalurgical and electrical properties.. lower resistance is better, higher conductivity is better.
1.591E-08______6.287E+07 ______Silver, Pure
1.664E-08______6.009E+07 ______Copper, Pure
2.463E-08______4.060E+07 ______Gold, Pure
2.826E-08______3.538E+07 ______Aluminum, Pure
3.918E-08______2.552E+07 ______Bronze, Commercial (Annealed)
4.660E-08______2.146E+07 ______Brass, Red (Annealed)
6.158E-08______1.624E+07 ______Cartridge Brass (Annealed)
1.611E-07______6.206E+06 _______Steel, Cast
6.897E-07______1.450E+06 _______Steel, 304 Stainless
7.184E-07______1.392E+06 _______Steel, 347 Stainless
[Resistivity = ohms/m, Conductivity = SIEMENS/m]
Out of copper & aluminium, aluminium is the easiest to work with and obtain as well as cheaper.
