### 2.2.4 Summary to: Conductors - General Applications

| No electrical engineering without conductors! Hundreds of specialized metal alloys exist just for "wires" because besides s, other demands must be met, too: |  | Money, Chemistry (try Na!), Mechanical and Thermal properties, Compatibility with other materials, Compatibility with production technologies, ...
|  | 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; ...
