Brass Plumbing Fittings

Brass plumbing fittings are commonly used in plumbing systems due to their excellent corrosion resistance, durability, and aesthetic appeal. However, not all brass plumbing fittings are created equal, and it’s essential to understand the different grades of brass and their properties to choose the right fittings for your application.

Brass is an alloy of copper and zinc, and its properties depend on the proportion of these metals. The most commonly used brass alloys in plumbing fittings are CW617 brass and 58-3 brass.IFAN Facebook Website:www.facebook.com，IFAN factory has 30+ years manufacture experience supporting color /size customization support Free Samples.

CW617 Brass

CW617 brass, also known as CW614N brass, is a lead-free brass alloy that contains 57-60% copper, 2.4-3.7% lead, and 0.5-1.9% iron. It’s commonly used in plumbing fittings due to its excellent corrosion resistance, high ductility, and low dezincification resistance (DZR). DZR is essential in plumbing fittings as it prevents the loss of zinc from the brass, which can lead to corrosion and eventual failure of the fittings.

58-3 Brass

58-3 brass, also known as C27400 brass, is also a lead-free brass alloy that contains 63-68% copper, 0.07-0.12% lead, and 0.03-0.06% iron. It’s commonly used in plumbing fittings due to its good corrosion resistance, high strength, and excellent brazing properties. This alloy is well-suited for applications where high strength and leak-tightness are critical.

The main difference between CW617 brass and 58-3 brass is their copper content. 58-3 brass has a higher copper content and lower lead content, making it stronger and more robust. However, it may be more challenging to work with than CW617 brass due to its higher melting point.

When selecting brass plumbing fittings, several factors should be considered to ensure you choose the right fittings for your application. These include:

1. Type of Application

Brass fittings come in various sizes, shapes, and designs. Depending on the application, you may require different types of brass fittings such as elbows, tees, reducers, or couplings. You should also consider whether the application will involve low or high pressure, as this will impact the type and size of the fittings needed.

2. Type of Pipe

The type of pipe you’re using will also determine the type of brass fitting required. Brass fittings can be used with different types of pipes such as copper, PVC, or PEX. Ensure that the fittings you choose are compatible with the pipe material to prevent leaks or corrosion.

3. Quality Standards

Ensure that the brass fittings meet quality standards and have the necessary certifications such as NSF, CSA, or UL. These certifications ensure that the fittings meet safety and performance standards, and they are suitable for use in drinking water systems.

4. Material Quality

Choose fittings made from high-quality brass alloys such as CW617 brass or 58-3 brass. Avoid fittings made from inferior materials that may contain lead or other harmful impurities that could lead to corrosion, leaks, or contamination of the water supply.

5. Brand and Reputation

Choose fittings from reputable brands known for producing high-quality and reliable products. Avoid cheap or unknown brands that may not have undergone proper testing and certification and may fail prematurely.IFAN has been focusing on pipelines for more than 30 years, quality assurance, welcome to consult!

In conclusion, selecting the right brass plumbing fittings depends on various factors such as the type of application, pipe material, quality standards, material quality, and brand reputation. By considering these factors, you can choose high-quality brass fittings that are durable, reliable, and suitable for your specific needs.
