What is Electrical Conductivity of Brass - Definition

The electrical conductivity of cartridge brass – UNS C26000 is about 30% IACS (around 17 MS/m). 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.

Brass is is the generic term for a range of copper-zinc alloys. Brass can be alloyed with zinc in different proportions, which results in a material of varying mechanical, corrosion and thermal properties. Increased amounts of zinc provide the material with improved strength and ductility. Brasses with a copper content greater than 63% are the most ductile of any copper alloy and are shaped by complex cold forming operations. Brass has higher malleability than bronze or zinc. The relatively low melting point of brass and its fluidity make it a relatively easy material to cast. Brass can range in surface color from red to yellow to gold to silver depending on the zinc content. Some of the common uses for brass alloys include costume jewelry, locks, hinges, gears, bearings, hose couplings, ammunition casings, automotive radiators, musical instruments, electronic packaging, and coins. Brass and bronze are common engineering materials in modern architecture and primarily used for roofing and facade cladding due to their visual appearance.

For example, UNS C26000 cartridge brass alloy (70/30) is from the yellow brass series, which has the highest ductility. Cartridge brasses are mostly cold formed and they can also be easily machined, which is necessary in making cartridge cases. It can be used for radiator cores and tanks, flashlight shells, lamp fixtures, fasteners, locks, hinges, ammunition components or plumbing accessories.

Electrical Conductivity of Brass – Cartridge Brass – UNS C26000

The electrical conductivity of cartridge brass – UNS C26000 is about 30% IACS (around 17 MS/m).

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. A low resistivity indicates a material that readily allows the flow of electric current. The symbol of resistivity is usually the Greek letter ρ (rho). The SI unit of electrical resistivity is the ohm-metre (Ω⋅m). Note that, electrical resistivity is not the same as electrical resistance. Electrical resistance is expressed in Ohms. While resistivity is a material property, resistance is the property of an object.
