The document discusses different types of conducting materials used in electrical engineering. It divides conductor materials into four groups: high conductive materials, materials used for making solders and contacts, materials of high resistivity, and other special materials. Some key high conductive materials mentioned are copper, aluminum, silver, and gold, as they possess high conductivity, low temperature coefficients, mechanical strength, and resistance to corrosion needed for electrical applications. The document provides a overview of important conductor materials used in electrical engineering.
2. CONDUCTOR MATERIALS

3. HIGH CONDUCTIVE MATERIALS
High Conductive materials must possess the following properties:
1. High conductivity
2. Lowest temperature coefficient
3. Sufficient mechanical strength
4. Good rollability and drawability for wire manufacturing
5. Adequate resistance to corrosion
6. Easily solderable 3
