### 2.3.4 Summary to: Conductors - General Applications

| No electrical engineering without conductors! |  |
Money, Chemistry (try Na!), mechanical and thermal properties, compatibility with other materials, compatibility with production technologies, ...
|  | Hundreds of specialized metal alloys exist just for "wires" because besides s, other demands must be met, too: |
|  | Example for unexpected conductors being "best" compromise: |  |
Poly Si, Silicides, TiN, W in integrated circuits.
| Don't forget Special Applications: |  |
Contacts (switches, plugs, ...); Resistors; Heating elements; ... Transparent conductors
