What is the Advantage and Disadvantage of Copper Wire Mesh

Copper mesh is also known as copper screen or copper wire mesh. The copper mesh is a square weave mesh that it woven by a copper wires which has great electrical and thermal conductivity. The copper is a malleable and soft material. A copper mesh is widely used as electromagnets interference. It can also be used as a shield for radio frequency interferences.  It is also used as a window screen or in different industries as filtration and separation.

Classification

Copper meshes can be further classified into medium, fine and coarse wire mesh. This is of course depending on the wire specification. The medium copper mesh includes the meshes that are in the range of 12 x 12 meshes up to 40 x 40 meshes. The fine meshes include the 50 x 50 mesh, 60 x 60, 80 x 80 and 100 x 100 mesh. The coarse mesh on the other hand include 2 x 2 mesh, 4 x 4, 6 x 6, 8 x8 and 10 x 10 mesh.

Copper mesh can also be subdivided into three types depending on the materials that it is made up namely the purpose copper mesh, brass wire mesh and the phosphor copper mesh.

Purple copper mesh.

The material used is purple copper wire which is 99.8 percent pure copper. This mesh is non-magnetic and is able to bear the pressure in grinding. It is widely used during filtration of electron beam as well as in electron display screen.

Brass wire cloth or brass wire mesh.

Material used is brass. There are different proportions and one of these is the 65 brass. For this material, it has 65 percent while the zinc is 35 percent. Another brass is the 80 brass material which contains 80 percent of brass proportion with the zinc only 20 percent. The brass wire cloth is non-magnetic, has good ductility and is wear resistant. It can be used as porcelain glass and clay, filtering gas and liquid, powder, and is also used to screen different granules.

Phosphor mesh.

This is also the alias used for tin bronze mesh. The material that makes up the phosphor mesh is phosphor copper wire. The proportion is 85 to 90 percent copper and the tin is about 5 to 15 percent. The phosphor mesh is non-magnetic; it is able to bear the grind alkali and ache and is also ductile.

Mesh sizes and shape

There are different mesh sizes. The usual wire diameter is in the range between .3mm to 1.2mm. The preferred diameter for the wire mesh by most consumers is .6mm. The opening size of the mesh on the other hand is usually in between 4mm to 6mm. The mesh is shaped into square and the copper bare mesh has the spacing of 300 x 300mm.

Advantages of copper mesh

Tensile endurance

Considering that copper is strong in addition to being versatile, it increases the reliability of the overall system even under unfavorable conditions.

Non-reaction with water

Copper does not react with water, but can react with oxygen in the atmosphere and also forms a dark brown layer of copper oxide. In contrast to the oxidation of iron by moist air, this formed layer of copper oxide prevents further deterioration.

Adaptability

Copper wire mesh is flexible and easy to install and handle. It can be quickly attached by welding, brazing or soft soldering. Its versatility means it can be used to adapt to different style configurations.

Durable and maintenance-free

Copper cable mesh is durable and requires very low maintenance, making it the preferred choice for many mechanical and industrial systems. It does not require any type of finish to prevent corrosion.

Biostatic

Bacteria will never expand on the copper grid.

Sustainability

Copper is recyclable and does not lose its high quality, whether you use it in its original state or in manufactured products. By comparison, copper is one of the most recyclable metals after lightweight aluminum and iron.

Safety and security.

It does not melt or burn continuously. Copper cable mesh does not carry fire, especially through walls, ceilings and floors. It also does not decay directly into toxic gases.

Copper mesh, also referred to as copper screen or copper wire mesh, is a square weave mesh made from copper wires, known for its excellent electrical and thermal conductivity. Copper is a soft, malleable material, making copper mesh ideal for various applications. It is commonly used to block electromagnetic interference (EMI) and as a shield against radio frequency interference (RFI). Additionally, copper mesh is utilized in window screens and in industries for filtration and separation purposes.

Known for its durability and long service life, copper mesh also carries a sense of wealth and prestige, which is why it is often used as a decorative element in building facades. Moreover, it serves as a strong and reliable plastering reinforcement material for ceilings and walls.

Classification

Copper mesh can be classified into medium, fine, and coarse types based on the wire specifications.

- Medium copper mesh includes mesh sizes ranging from 12 x 12 to 40 x 40.

- Fine copper mesh includes sizes such as 50 x 50, 60 x 60, 80 x 80, and 100 x 100.

- Coarse copper mesh consists of mesh sizes like 2 x 2, 4 x 4, 6 x 6, 8 x 8, and 10 x 10.

Copper mesh can also be categorized by the materials used, resulting in three main types: pure copper mesh, brass wire mesh, and phosphor bronze mesh.

1. Pure Copper Mesh  

Made from 99.8% pure copper wire, this mesh is non-magnetic and can withstand grinding pressure. It is commonly used for electron beam filtration and in electronic display screens.

2. Brass Wire Mesh  

Made from brass, this mesh comes in various compositions. One common type is 65 brass, containing 65% copper and 35% zinc, while another is 80 brass, with 80% copper and 20% zinc. Brass wire mesh is non-magnetic, ductile, and wear-resistant. It is used for filtering gases and liquids, as well as screening powders and granules, and is commonly applied in porcelain, glass, and clay industries.

3. Phosphor Bronze Mesh  

Also known as tin bronze mesh, this type is made from phosphor copper wire, containing 85–90% copper and 5–15% tin. It is non-magnetic, resistant to alkali and acid corrosion, and has good ductility, making it suitable for various industrial applications.

Mesh Sizes and Shapes

Copper mesh is available in various sizes, with wire diameters typically ranging from 0.3mm to 1.2mm. The most commonly preferred wire diameter among consumers is 0.6mm. The opening size of the mesh usually falls between 4mm and 6mm. Copper mesh is typically shaped into squares, with bare copper mesh often having a standard spacing of 300 x 300mm.

Advantages of Copper Mesh

1. Tensile Strength  

Copper is both strong and versatile, which enhances the reliability of systems, even in unfavorable conditions.

2. Non-Reactivity with Water  

Copper does not react with water, though it can react with oxygen to form a protective dark brown layer of copper oxide. Unlike iron oxidation, this copper oxide layer prevents further corrosion, maintaining the material's integrity.

3. Adaptability  

Copper mesh is flexible, easy to handle, and simple to install. It can be quickly secured through welding, brazing, or soft soldering, making it adaptable to various design configurations.

4. Durable and Low Maintenance  

Copper mesh is highly durable and requires minimal maintenance, making it a preferred material for mechanical and industrial systems. It is naturally corrosion-resistant and does not require additional finishing.

5. Biostatic Properties  

Copper's biostatic nature prevents the growth of bacteria on its surface.

6. Sustainability  

Copper is fully recyclable and retains its high quality, whether reused in its original form or as part of manufactured products. It is one of the most recyclable metals, alongside aluminum and iron.

7. Safety and Security  

Copper mesh does not melt or burn easily, and it does not propagate fire through walls, ceilings, or floors. Additionally, it does not decompose into toxic gases when exposed to high temperatures.
