Brass is an alloy made up of copper and zinc. Brass made up of copper and zinc is called ordinary brass. If it is made up of more than two elements, then it is called special brass. Brass has a strong wear resistance, and is often used in the manufacture of valves, water pipes, air conditioning connection pipe and radiator.
Copper, also known as red copper for its purple and red color. Copper is the industrial pure copper, with a melting point of 1083℃, no isomorphic transformation, and a relative density of 8.9, five times that of magnesium. The mass of the same volume is about 15% heavier than that of steel.
Copper is commonly referred to as red copper because of its rosy red color and purple color after oxidation film is formed on the surface. It is copper containing a certain amount of oxygen, so it is also called oxygen-containing copper. Copper has very good conductivity and heat conductivity, plasticity is very good, easy to heat and cold pressure processing. It is widely used to manufacturer components with good conductivity requirement, such as wire, cable, etc.
Differences Between Brass and Copper
Brass: light golden yellow, shiny.
Copper: rosy and shiny finish
2. Chemical Composition
Brass: About 60% copper; About 40% zinc; Some grades contain lead 1% or so with impurities.
Copper: copper content reaches 99.9%.
Brass: Slightly high.
Copper: Slightly low.
Brass: The density of brass (8.93g/cm3). Forged brass parts are often used to make valves and pipe fittings.
Copper: Pure copper, also known as red copper, density (7.83g/cm3), melting point of 1083 degrees, no magnetic.
