![]() ![]() Water pipes – Used because it is ductile (soft) yet tough and strong. Pins in a 13A plug – Used because it is an electrical conductor that has low reactivity and is strong. Some of the common uses of copper include: Many common applications also rely on one or more beneficial properties, such as the fact that it is a good thermal conductor or has low reactivity (reaction with water and acids). Always do as much research as possible! What Is Copper Used For?īecause Copper is an excellent electrical conductor, most of its common uses are for electrical purposes. ![]() As mentioned, Brass has a very low conductivity rating despite containing copper, so it is very important that assumptions are not made on the electrical conductivity of a material. A 100% rating does not indicate no resistance.Īs you can see the differences in electrical conductivity vary considerably depending on the metal. * Conductivity ratings are expressed as a relative measurement to copper. So if all metals conduct electricity, how do they all rank? Take a look at this chart: Material IACS (International Annealed Copper Standard) It is also more expensive than copper and the slight increase in conductivity is not worth the added cost. #Does copper and brass conduct together skinThis issue can cause problems in applications where skin effect is important, such as with high frequency currents. The problem with Silver is that it can tarnish. Which Metal Conducts Electricity The Best? While Gold does have a relatively high conductive rating, it is actually less conductive than Copper. Another common misconception is that pure Gold is the best conductor of electricity. You may be surprised to learn that copper is not even the most conductive metal despite being used in many common applications (and the fact it is used as the measuring stick for rating conductivity in metals). 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. It is highly conductive which is why it is has been used in electrical wiring since the days of the telegraph. While all metals can conduct electricity, certain metals are more commonly used due to being highly conductive. More simply, it is how easily an electrical current can flow through a metal. Electrical conductivity is the measured amount of current generation created on a metal target’s surface. ![]()
