Typical conductor material for power cable is copper and aluminium.
The use of other materials may be needed in special applications. Some materials can be found on elektrisola
- Bronze (Brz): Bronze (CuSn10) is an alloy that consists primarily of copper (90%) with the addition of other ingredients. In most cases the ingredient added is typically tin (10..30%), but arsenic, phosphorus, aluminum, manganese, and silicon can also be used to produce different properties in the material. All of these ingredients produce an alloy much harder than copper alone.
- Brass (CuZn): Brass (CuZn) consists of copper and 6..11% zinc plus small amounts of lead (Pb <0.05%) and iron (Fe <0.05%). It has very good mechanical properties and corrosion behavior, comparable to that of copper. The low conductivity and the outstanding bending proof performance makes it the preferred choice for heating applications. Furthermore, bare wire is suitable for electric discharge removal of material (spark erosion). Copper zinc alloy wire is available in all insulation and self-bonding enamel types, as well as bare wire and litz wire.
- Nickel (Ni): Nickel is especially characterized by very high resistance to oxidation and chemical corrosion. Wires of pure nickel are mainly used for the manufacture of connections for heating elements.
- Stainless Steel (SS): Stainless steel wires are suitable for several industrial applications.
