Brass Flanges is an alloy consisting of zinc and copper. The proportion of these elements can be adjusted to achieve different types of brass alloys. Along with Zinc and copper as the base metals, other elements can also be added to brass. For example, phosphorus, aluminium, arsenic, lead, manganese, and silicon added to brass depending on its end use. Brass Threaded Flange is widely used and can be found in a number of applications, including electrical components, appliance parts, fasteners, connectors, and ammunition components.

Brass Companion Flanges

Brass Floor Flange is composed of copper and zinc; the proportions of zinc and copper can be varied to create a range of brasses with varying properties. We offers a variety of Brass Pipe Flange in sizes and quantities to meet the needs of any project.

We are leading Brass Flanges suppliers Listed below are some Brass Closet Flange grades and uses -

Cartridge brass or Yellow brass also known as 260 brass is composed of 70% copper and 30% zinc. Yellow brass is ideal metal for shell casings in Ammunition components. yellow brass stock has desirable properties like malleability and ductility due to addition of lead. Therefore, it can be easily worked and formed as required. Yellow brass also finds applications in Plumbing accessories, Radiator cores, fasteners and tanks. Metals like arsenic and tin are added to the alloy to increase its strength, stability and hardness.

• Red brass is a particularly strong kind of brass.
• 330 brass is used in applications that contain tubing and poles. It is both machinable and workable.
• Free machining brass or 360 brass, have high lead content. The high content of lead makes it soft therefore it is easy to cut and shape.
• Naval brass, also known as 464 brass, is highly resistant to corrosion. Brass is known to have natural bactericidal properties and it prevents bio fouling in marine environments. Thus, it is ideal for use in seawater.

Since brass is susceptible to stress corrosion cracking, it is annealed to increase its resistance to the corrosion.

Solid brass stock finds applications that require low friction e.g. - gears, bearings, doorknobs, fittings and valves; for plumbing and electrical applications; and workability and durability is desired. It is also used in zippers.

Brass Companion Flange is used in fittings and tools used near flammable or explosive materials. Since explosives can cause sparks, brass fittings and tools prevent formation of sparks.
