Quite often our customers will ask our team here at Shanghai Metal about the different types of metal, and what to look for when selecting grades, shapes and sizes. A metal is one of the basic elements in nature. Over three-quarters of the more known elements are metal. Metal is an ideal conductor of electricity and heat. Physically, metal is generally hard, heavy and tenacious. Brass, specifically, is a binary alloy composed of Copper and Zinc that has been produced for millennia and is valued for its workability, hardness, corrosion resistance and attractive appearance.
Properties of Brass
As mentioned above, brass is a binary alloy. It consists of Copper and Zinc. A few important properties of brass include:
Density: 8.3-8.7 g/cm³
Melting Point: 1652-1724°F (900-940°C)
Moh’s Hardness: 3-4
for the machinability, or the ease with which the metal can be formed into desired shapes and forms while retaining high strength. There are differences between
brasses with high and low zinc contents, but all brasses are considered malleable and ductile (low zing brasses more so). Since brass has a low melting point,
it can also be cast relatively easily, but for casting applications, a high zinc content is typically preferred. Brasses that have a lower zinc content can be easily cold worked,
welded and brazed. A high copper content also allows the metal to form a protective oxide layer (patina) on its surface that protects against further corrosion.
This is a valuable property in applications that expose the metal to moisture and weathering.
Brass has both good heat and electrical conductivity (its electrical conductivity can be from 23 percent to 44 percent of pure copper), and it is wear and spark resistant.
non-magnetic alloy, while its acoustic properties have resulted in its use in many ‘brass band’ musical instruments. Artists and architects also value the metal’s aesthetic
properties, as it can be produced in a range of colors, from deep red to golden yellow.Types of Brass
Depending on the properties required for particular application, these alloys can have a wide range of different compositions.Applications
