The electrical conductivity of copper and brass became utilised with the discovery by Michael Faraday in 1831, that electricity could be viable for use in technology. 898 ELECTRICAL CONDUCTIVITY OF SELECTED MATERIALS Material Conductivity, mho/m Resistivity, ohm-m Source Polybutylene terephthalate 4 ×1014 [2] Polycarbonate 2 ×1014 [2] Polyester 1013 [2] Polyetheretherketone 6 ×1014 [2] Polyethylene terephthalate 1012 [2] Polyvinyl chloride >1014 [2] Cellulose acetate 108 − 1013 [4] Polyimide 4 ×1013 [4] Polyarylsulfone 3.2 ×1014 –7.71 ×1014 [4] Most metals conduct electricity. Brass however – which contains copper – is far less conductive because it is made up of additional materials that lower its conductivity, making it unsuitable for electrical purposes. There are many copper zinc alloys , with copper content from 15 % Zn, known as red brass, to 40% zinc , a yellow brass. Nickel is an element with high electrical conductivity. Some of the key differences to keep in mind when selecting sheet metal materials include: Brass is a general term for a set of copper-zinc alloys that may include additional metals such as lead. Brass is a tensile metal used for smaller machines because it is easy to bend and mold into different parts. Electrical resistivity and its converse, electrical conductivity, is a fundamental property of a material that quantifies how strongly it resists or conducts the flow of electric current. The electrical conductivity of cartridge brass – UNS C26000 is about 30% IACS (around 17 MS/m). Although copper, brass, and bronze provide electrical and thermal conductivity, corrosion resistance, and strength, there are distinct differences between the three metals. Brass Conductivity. Brass is a generic term for a range copper/ zinc alloys. Nickel Conductivity. Different types of brass have different properties, but all brass is strong, machinable, tough, conductive, and corrosion resistant.This along with beauty and ease of production make brass one of the most widely used alloys.
