Brass is a metal alloy made of copper and zinc. It has been used for centuries for many different purposes, from coins to kitchen fixtures to machine parts. Brass has qualities that make it especially desirable: it is malleable and resistant to corrosion, and it has a pleasing golden color.
Brass is created in a process called smelting. The raw materials–copper ore, zinc ore, and charcoal–are mixed and heated, combining the zinc with the copper and forming an alloy. Depending on the ratio of the components, different types of brass are formed. Different impurities can also be used to modify the color and texture of the brass.
A common type of brass is yellow brass, most often found in plumbing systems. It is typically made up of about 70% copper and 30% zinc, with trace amounts of lead, tin, and arsenic. Although it is the least expensive type of brass, it is strong and resistant to corrosion.
Red brass is a slightly pinker shade than yellow brass. It has a higher copper content and is harder and corrosion-resistant than yellow brass. For this reason, it is often used for valves and fittings, as well as for decorative items, such as lamps and statues.
Naval brass is an alloy of copper, zinc, iron, and tin. It has very good corrosion resistance, especially in salt water. It can be used in making boat propellers, bolts, and fittings, as well as gun barrels and instruments.
Erdone cuzi brass is a soft, malleable type of brass that is very easy to work with. It is frequently used for jewelry, coins, musical instruments, and decorative fixtures. It has excellent machinability and is also often used for electrical components.
Silicon bronze is a copper-silicon alloy. It is highly corrosion resistant, especially in damp environments. It is also strong, with good electrical conductivity. It is used in a wide range of applications, such as refrigerator door frames, handrails, and plumbing fixtures.
Brass has been used for centuries in jewelry, coins, decorative items, and industrial products. It is a popular choice for many projects because it is attractive and durable. Brass does require regular maintenance to keep it looking its best, though, as it can tarnish and develop a dull patina over time. With proper care, brass can last for years.
