What is CW602N Brass – Properties & Applications Explained

CW602N is a type of lead brass that comprises different layerings that are majorly designed to prevent corrosion of zinc during the working process. Its main function is to prevent dezincification of the brass.

Benefits of CW602N Brass Valve

Highly resistant to corrosion actions – which enables it to prevent zinc from corrosion. It contains hard elements in its composition which enables it to retain the tough nature and lower corrosion rate.

It is ductile – hence can be forged under hot temperatures forming a different structure desired based on the function needed. This enables it to be able to design a number of products in the manufacturing companies and also plumbing sectors.

Strong under room temperature – CW602N brass is solid at room temperature. The presence of elements like Lead and Copper makes the brass hard and compact in nature thus retaining strength unless it is exposed to high temperatures.

Good alloy during the machining process – This is due to its ductile nature that allows the machining process to be soft and applied while forming different products.

Limitations of CW602N Alloy Brass

It can gain a different undesirable color if not well maintained. Tarnishing may also occur due to exposure to most areas that will increase the oxygen levels hence leading to different chemical reactions that give different results to the product.

Maintenance of CW602N brass is costly since the quality of the brass has to be observed to avoid issues like tarnishing effect. This also means the storage should be observed to avoid brass reactions with moist conditions.

It can cause skin effects if not well treated due to the presence of copper elements and zinc elements. Copper and zinc have an itchy effect and are allergic and hence might create discomfort to the handlers or users.

CW602N brass is not as durable as other materials like stainless steel. CW602N brass is not as strong as stainless steel and it’s prone to ductility and hence requires continued maintenance.

It is prone to wear and tear in the long run.

Chemical Element Composition

CW602N Brass comprises of Copper, Lead, Zinc, Nickel, Iron, Tin, Aluminum, and Arsenic elements.

Chemical Properties

Prone to tarnishing due to the presence of zinc and copper. Tarnishing is majorly caused by a reaction of oxygen and the zinc or copper elements in the alloy composition.

Highly resistant to corrosion actions as it forms a hard material. This makes it a good alloy used to prevent dezincification.

Prevents zinc corrosion in material formation. CW602N brass has a hard surface, solid under room temperature. This offers a better surface alloy that prevents corrosion during the working process.

Tough, hence cannot easily be cracked down. This is also because of its solid nature which makes it harder and not easy to break.

Has a higher heat molding nature since it is a solid at room temperature.

Provides good machinability features during the working process. This is based on its nature of ductility which allows it to form a new product.

Again, this brass alloy has a density of 8.44g/cm3

It conducts electricity around 13.4MS/M due to the presence of copper and zinc. Besides, its thermal conduction ranges at 116W/mK

The brass has a solidifying range of 880-915 degrees Celsius. This makes it solid at room temperature.

Offers both hard and soft soldering connections. It is solid at room temperature but when exposed to heat, it appears soft and ductile.  Additionally, It is resistant to materials organic and alkaline materials too.

Mechanical Priorities of Brass CW602N

It has a high tensile strength. This allows it to retain toughness when acted upon hence cannot easily be broken down.

On the other hand, the yielding strength is higher due to the nature and element composition of the brass alloy.

Also, this brass alloy is prone to elongation during the process. CW602N brass being ductile in nature, it can be elongated to form different products.

Lastly, this brass alloy is a hardy material when worked on. Its hardness is due to its solid state.

Uses of Brass CW602N Plumbing Industry

  • Used to make valves for connection of pipes.
  • Used in systems that handle fluid materials.


CW602N brass is a hard type of brass that is mostly applicable to plumbing activities. Generally, this brass alloys exhibit some superior properties making perfect choice for most applications.
