Although brass is considered a good electrical conductor, it is only 28% more conductive than copper. While copper is most commonly used for standard electrical applications, there are situations where brass is the preferred material due to its high tensile strength, corrosion resistance, or other properties.
Alloys of copper, brass and bronze are non-ferrous metals with excellent electrical and thermal conductivity, as well as good corrosion resistance, ductility and strength. Copper is a soft, malleable (low hardness) reddish-orange metal that conducts heat and electricity well.
Conductivity of Brass The advantages over steel are that it is slightly more conductive, cheaper to buy, less corrosive than steel and retains its value after use. Brass is an alloy.

The worst conductor of heat among metals is bismuth. Stainless steel is also a bad conductor of heat and is used a lot in everyday life! Other bad conductors are titanium, lead and chromium. And ironically, mercury, the liquid metal used in thermometers!
When we mix zinc and copper to form the brass alloy, we also get a non-magnetic bond. Brass is therefore not magnetic. Like aluminum, copper and zinc, brass interacts with moving magnets. In the video below, a copper plate moves fast on a pendulum without a magnet.
The exact properties of the different types of brass depend on the composition of the brass alloy, in particular the copper-zinc ratio. The metal has both good thermal conductivity and good electrical conductivity (the electrical conductivity of pure copper can be between 23% and 44%) and is resistant to wear and sparks.
Like all metals, stainless steel is a relatively good conductor of electricity. The body is also a good guide through the water. The skin is a relatively weak conductor of electricity through ■■■■ skin cells. Any break in the skin, i.e. cuts, greatly reduces the resistance.
Plastic, rubber, wood and ceramic are good insulators. These are often used to make kitchen utensils such as handles to prevent the heat from rising and burning the cook’s hand. Plastic coatings are also used to cover most of the electrical wiring in devices. Air is also a good thermal insulator.
Tin is a conductor of both electricity and heat, but it’s not that good. Tin is a good conductor of electricity because surface electrons are not localized.
While all metals can conduct electricity, some metals are more commonly used because they are very conductive. However, copper-containing brass is much less conductive as it is made up of additional materials that reduce conductivity, making it unsuitable for electrical purposes.
Brass offers much better thermal conductivity than stainless steel or carbon steel. In fact, it is twice as conductive as carbon steel and 15 times as conductive as austenitic stainless steel.
Clean water is not a good conductor of electricity. Ordinary distilled water in equilibrium with the carbon dioxide of the air has a conductivity of about 10 x 106 W1 * m1 (20 dS / m). Since the electric current is carried by the dissolved ions, the conductivity increases as the ion concentration increases.

The form of carbon that conducts electricity well is graphite. Graphite is an allotrope of carbon that has the properties of metal and non-metal. The reason why graphite is a good conductor of electricity is due to the mobility of electrons in the outer valence layer.
Brass is an alloy of copper and zinc. Different types of brass are created through different proportions of copper and zinc. Metallic brass is basically malleable and ductile. Its properties may vary depending on the composition of the copper and zinc contained, as well as other added elements.
Bronze is a better conductor of heat and electricity than most steels. The cost of copper-based alloys is generally higher than that of steel, but lower than that of nickel-based alloys.
