Advantages and Disadvantages of Brass Over Copper

Brass and copper are both highly valued metals for their malleability, durability, and conductivity. For centuries, these two metals have been used in various applications, from manufacturing to architecture. But how do brass and copper compare? Let’s take a look at the advantages and disadvantages of each metal.

 

 

5 Advantages of Brass Over Copper

Brass is an alloy composed of copper and zinc. Adding zinc to the copper makes brass stronger than pure copper while retaining many properties, such as malleability, corrosion resistance, and conductivity. This makes brass a desirable choice for applications where strength is needed, but flexibility is also desired.

Another advantage that brass has over copper is its antimicrobial properties. Studies have shown that brass can kill up to 99% of bacteria within 24 hours due to the zinc content in the alloy when exposed to sunlight. This makes it an excellent choice for items such as door handles or fixtures that come into contact with human skin regularly.

More Durable

One of the primary advantages of brass over copper is that it is more durable. Brass is an alloy of copper and zinc, typically much more robust than pure copper. This makes brass less likely to dent or scratch, and it also makes it less susceptible to corrosion.

Better Thermal Conductivity

Brass also has better thermal conductivity than copper. This means that it can more effectively transfer heat, making it an ideal material for use in heat exchangers and other applications where heat needs to be moved quickly and efficiently.

Lower Cost

Another advantage of brass over copper is that it is typically lower in cost. This is because brass is an alloy, and the production of alloys typically requires less energy and resources than pure metals. Additionally, brass scrap can be recycled and reused, reducing its cost.

Easier to Machine

Brass is also easier to machine than copper. This is because brass is softer, making it easier to cut and shape. Also, brass machines work well, meaning they can be turned into intricate shapes without breaking or cracking.

Aesthetically Pleasing

Finally, brass has a warm golden color that many people find aesthetically pleasing. Copper can also have a similar color but frequently has a greenish tint that some people do not see as attractive.

5 Disadvantages Of Brass Over Copper

The main disadvantage that brass has over copper is its cost. Since it takes more resources to produce an alloy than pure metal, brass tends to be more expensive than pure copper by weight. Additionally, because it is an alloy, it can be challenging compared to pure metals like copper, which can be easily shaped or formed with hand tools or light machinery.

Lastly, since brass contains a higher percentage of zinc than copper, it tends to corrode more quickly when exposed to certain elements such as chlorine or salt water. Therefore, if you plan on using either metal outdoors, consider using pure copper instead since it will last longer in harsh conditions without rusting as quickly as brass might.

More expensive

Brass is typically more expensive than copper due to the higher cost of raw materials and the additional processing required.

Lower thermal conductivity

Brass has a lower thermal conductivity than copper, meaning it could be better at conducting heat. This can be an issue in applications where heat needs to be transferred quickly, such as in cooking or heating applications.

Lower electrical conductivity

Brass also has a lower electrical conductivity than copper, which means it could be better at conducting electricity. This can be an issue in applications where electrical current needs to be transferred quickly, such as in electrical wiring applications.

Tarnishes easily

Brass tarnishes easily when exposed to air, water, or other chemicals. This can cause discoloration and surface imperfections that are difficult to remove.

Difficult to work with

Brass is a complex material due to its high melting point and tendency to crack when heated. This makes it challenging to fabricate and shape into the desired final product.

 

 

Conclusion:

In conclusion, many benefits come with using brass and copper in various applications, from manufacturing products to architecture projects. While both metals offer durability and malleability, among other things, there are some differences between them, including cost and corrosion resistance which should be taken into consideration before making your final decision about which one is right for your needs. Ultimately though, no matter which one you choose, you can rest assured knowing that either one will provide you with quality results!
