Brass, alloy of copper and zinc, of historical and enduring importance because of its hardness and workability. The earliest brass, called calamine brass, dates to Neolithic times; it was probably made by reduction of mixtures of zinc ores and copper ores.

Properties of Brass
As a copper-alloy, brass demonstrates many of the properties characteristic of copper. However, the alloy does exhibit a few distinct properties compared to pure copper and other copper alloys. For example:
- Susceptibility to stress-cracking. As brass is stronger and stiffer than pure copper, it is more susceptible to developing stress cracks.
- Malleability and formability. Compared to bronze, brass is more malleable. Additionally, it is easy to cast or work.
- High melting point. Brass has a melting point of approximately 900°C. The exact melting point differs based on the concentration of different metals in the alloy.
- Non-ferromagnetic. As brass is not ferromagnetic, it is much easier to process for recycling.
Depending on the additional metals added to the alloy, it can demonstrate varying characteristics, such as a variable melting point or greater corrosion resistance (due to the presence of manganese).
Available Grades of Brass
Brass is available in a variety of grades, each of which is characterized by the exact material makeup. At Sequoia Brass & Copper, we provide these six grades of brass:
- Alloy 260. Also known as cartridge brass, Alloy 260 demonstrates good cold working properties. It is suitable for use in ammunitions, automobiles, fasteners, and hardware.
- Alloy 272. This alloy—also referred to as yellow brass—consists of 33% zinc. It is typically used in industrial and architectural applications.
- Alloy 330. Brass alloy 330 is suitable for application where high machinability is critical. It contains a low lead content sufficient for cold-working and is commonly used to produce pipes.
- Alloy 353. Alloy 353 (also referred to as clock brass) is often used to fabricate precision components, such as clock and watch parts, because of its excellent machinability.
- Alloy 360. Also known as free cutting brass, this alloy is the most common type of brass. It exhibits excellent machinability and formability, as well as suitability for soldering and brazing operations. It commonly finds application in the manufacture of hardware components, fittings, valves, and fasteners.
- Alloy 385. Also known as architectural bronze this alloy can be used for construction & architectural applications. Alloy 385 is available in a wide variety of extruded & drawn shapes such as angles, channels, square tube, hand rail moulding & more.
- Alloy C48200 – C48500. Leaded naval brass meanto for machining. Typically available in rounds.
- Alloy 464. Alloy 464 (or naval brass) is known for its excellent resistance to corrosion from seawater across a wide range of temperatures. Additionally, it demonstrates suitability for hot forming and hot forming, as well as drawing, bending, heading, soldering, brazing, and welding.
