Why is Copper Wire Mesh Better?

Copper and its alloys have been used for thousands of years, so it is no surprise it is a highly demanded option within the wire mesh industry. Copper wire mesh is ductile, malleable and has high thermal and electrical conductivity. As a result, it is popularly used as RFI shielding, in Faraday Cages, in roofing, in HVAC and in numerous electrical-based applications. Darby proudly stocks one of the most complete inventories of copper wire mesh in the United States, ranging from 2 x 2 Mesh to 200 x 200 Mesh.

Copper wire mesh is durable in many types of atmospheres and environments. Although it is softer than a similar stainless steel wire mesh, it is also resistant to atmospheric corrosion but attacked by oxidizing agents such as nitric acid, ferric chloride, cyanides, and ammonia acid compounds. Darby’s copper wire mesh is woven to the industry standard, ASTM E-, is 99.9% pure copper and, when exposed to the atmosphere, will naturally develop a thin green layer, known as patina.

The unique color of copper wire mesh makes it a very popular option for many different types of users, including designers, artists, architects and homeowners. Residential customers and designers opt for copper woven wire mesh for residential projects including gutter guards, soffit screens, insect screen, fireplace screen, or even custom manufactured infill panels or decorative wall panels. Sculptors, wood workers, metal artisans and architects also prefer copper mesh because of its remarkable dark amber-red color and its broad appeal to a wide audience.

Without a doubt, copper wire mesh is critical to many industries, and it is often at the center of technological advancements in a broad range of fields. Over the past few years, customers have selected various copper mesh specifications for use in:

Pure copper wire mesh is a perennial favourite of our industrial customers thanks to its unique properties. Mesh made of copper is a highly conductive and corrosion-resistant material that is available in various sizes, making it ideal for myriad applications and project.

As more customers explore the benefits of copper wire mesh, we thought it would be helpful to outline some of the main benefits of this material with this article. 

Let’s get into it….

Pure copper wire mesh is an excellent conductor of electricity. This makes it a go-to material for applications where high conductivity is essential, such as in electrical circuits, grounding, and shielding applications.

Copper mesh has high thermal conductivity, which makes it an ideal material for heat sinks, electrical appliances, and power distribution applications.

This metal boasts excellent corrosion resistance and can withstand harsh environments.

Copper wire mesh is known for its resistance to corrosion. This is due to the fact that copper is a naturally corrosion-resistant metal as it forms a protective oxide layer on its surface when exposed to air. This layer, called a patina, helps prevent further corrosion of the metal.

This resistance makes it a popular choice for marine applications, as well as outdoor usage. Copper wire mesh holds up well against exposure to saltwater, UV radiation, and a variety of chemicals, making it ideal for use in pools, sewage plants, and agricultural applications.

However, when copper wire mesh is exposed to air and moisture over time, it may develop a greenish coating known as verdigris. This is a natural occurrence and is caused by the oxidation of the copper in the mesh. The verdigris coating is a mixture of copper compounds, including copper carbonate and copper chloride.

While some people may find the verdigris coating aesthetically pleasing, it can potentially impact the functionality of the copper wire mesh, especially if it’s being used for electrical purposes. The verdigris coating can increase the electrical resistance of the mesh and affect its conductivity.

Copper wire mesh is known for its robustness and durability, making it ideal for heavy-duty applications.

8 Holes Per Inch – 2.55mm Hole

This is the largest hole copper mesh that we currently stock.  It is the best material to demonstrate how strong and durable copper can be. 

It is extremely malleable and easy to form.

We recommend it for rodent control as not only is it tough, rats and mice also have a dislike of the taste of copper. The exact reason for this aversion is not fully understood, there are a few possible explanations.

The leading theory is that rats have an innate dislike for the taste of metals like copper, which they may associate with unpleasant or harmful substances. Another possibility is that the copper taste may be too strong or overwhelming for the rats, causing them to avoid it. We just don’t know at this point. We just know that it works very well in internal vents and gaps. 

Pure copper wire mesh can be aesthetically pleasing and adds a touch of class and elegance to any décor.

The standard copper colour is considered to be very appealing, and it only improves in time as it ages and turns verdigris. This can be a unique feature in a multitude of decorative applications, including arts and crafts, interior design, and fashion. 

Of course the most common creative being sculpture. Everyone is familiar with Lady Liberty. But you may not be aware that she is made of 2.4mm thick copper sheeting.  This is great example of the colour that copper can end up. 

Copper wire mesh is eco-friendly and recyclable, making it a sustainable material that conserves the earth’s resources.

Copper is one of the few elements that can be recycled without losing its strength, making it an ideal material for companies looking to reduce their carbon footprint and increase their sustainability.

It’s lack of biodegradability is also not an issue. While copper wire mesh may not biodegrade, it does not release harmful toxins into the environment. This means that even if it is disposed of, it will not have a negative impact on soil or water quality.

It is also long lasting, which also improves its eco credentials.
