Brass Valves vs. Copper Valves

February 13, 2019 - "Blog"



The material of a valve plays an important role in its efficiency. While it is easy to forget the importance of this detail, it does make a difference. Some materials excel in certain industries and fall short in others. For this reason, it is important to learn which material will best serve your application. This post will compare the differences between brass and copper valves. Below, you can find useful information about each type, as well as the different applications that they serve best.



Copper has been used in a variety of ways for thousands of years. This tried and true metal has high levels of strength, conductivity, and resistance to corrosion. In particular, the resistance to corrosion is an important trait for a valve. This material also has unique antimicrobial qualities that the Greeks believed purified their drinking water. It is easy to polish and buffer copper to meet any special needs you might have.
Because of its conductivity, copper is extremely useful when used with electrical equipment. Aside from its conductivity, copper’s malleability and ductility also make it the ideal material for these applications. From computer technology to portable electronics, copper has upheld its ancient reliability into the modern age. The construction industry also has a high use for copper valves and materials due to its lightweight durability.


Brass is an alloy made of copper and zinc. Because of this, brass valves have many of the benefits of copper valves. However, this material has a higher aesthetic quality as it bears a strong resemblance to gold. This material proves to be even stronger than copper because of the addition of zinc. While it is very efficient when used with hot temperatures, it is not as good with cold temperatures.
Brass valves are extremely versatile in the areas where they excel. The plumbing industry is one of the best industries for brass valves. This type of material can handle extremely high water temperatures, but cold water temperatures cause these valves some trouble. While brass contains much lower levels of lead than some materials, such as bronze, its presence in brass is still a factor to consider. There are no concerns about corrosion with brass valves due to its high resistance, which is an important quality to have in plumbing products.

Differences Between Brass and Copper Valves

Though copper makes up brass, these two valve types have their own unique benefits and drawbacks. The differences between brass and copper valves range from their looks to abilities. Their benefits help define the industries and applications in which they are best used. By paying attention to the qualities of different materials, you help to increase the efficiency of your systems and applications.
