Brass and copper are two common copper alloys that differ in composition, properties, and uses. Here are some of the main differences between brass and copper:
1.Ingredients:
Copper (also known as pure copper or red copper): Mainly copper (Cu) element, the copper content is usually as high as 99More than 9%, it is the purest form of copper.
Brass: is an alloy of copper (Cu) and zinc (Zn), usually between 55% and 90% copper, with zinc content making up the remainder. Some special brass may also contain other elements, such as lead (PB) or tin (sn).
2.Exterior Color:
Copper: has a fuchsia or rose-red appearance with a glossy surface.
Brass: It is pale golden yellow or yellow in appearance, and the surface is also shiny.
3.Density and hardness:
Copper: higher density, about 89 to 895 grams cubic centimeter, relatively low hardness.
Brass: Less dense, about 852 to 862 grams cubic centimeter, high hardness.
4.Performance:
Copper: It has good electrical and thermal conductivity, strong corrosion resistance, but low strength.
Brass: Poor electrical and thermal conductivity, but higher strength and poor corrosion resistance.
5.Usage:
Copper: It is commonly used in the manufacture of electrical and electronic equipment, pipes, crafts, etc., especially in applications that require good electrical conductivity.
Brass: Widely used in the manufacture of valves, pipe fittings, decorations, furniture, musical instruments, etc., especially in applications that require a certain strength and corrosion resistance.
Copper: Usually more expensive than brass because it is the purer form of copper.
Brass: Relatively low because it contains zinc at a lower cost.
Brass and copper have their own characteristics in composition, performance, and use, and the choice of material depends on specific application needs and cost considerations.
