What is copper wire mesh?
Copper woven wire mesh is also referred to as red copper wire mesh, pure copper wire mesh, copper mesh, copper mesh cloth, copper mesh fabric, copper screen, ….
Copper wire mesh can be woven with wire threads by plain weave, twill weave, dutch weave. In other words, it’s created by weaving wires in an over-under pattern. Each warp wire and each weft wire pass over one, two or other amounts of wires, and then under the next one, two or other amounts of wires. In addition, two distinct sets of wires are straight and at right angles to each other.
For example, plain woven wire mesh is the mesh where warp and weft wires pass over one, and then under the next adjacent wire in both directions.
Wire mesh copper varies widely in their mesh size, wire diameter, hole size. For instance, 16 20 22 60 80 100 120 150 180 200 250 mesh copper screen. Moreover, it can be cut, formed into many kinds of shapes, like round / rectangular copper mesh discs for industrial use, copper mesh sheet, fine copper mesh sheet, metal mesh filter caps, …
So it is suitable for a wide range of applications for shielding, screening, filtering, sieving, sorting, separating, supporting, etc.
Specifications of copper wire mesh
Material: pure copper (one of the commonly used copper alloys). We often call pure copper mesh as red copper wire mesh as a result of its color is reddish brown.
Weaving types: plain weave, twill weave, etc. Weave types are different because of different interlacing of warp and weft wires and different wire diameter.
Mesh counts: 2-300 mesh
Wire diameter: the thickness of one single wire
Opening / Aperture / Hole size: the distance between two adjacent parallel wires
Micron size: it can also tell us something about the copper screen mesh. A micron is defined as one-millionth of a meter. Micron is the measure of length, and is most frequently used to describe particle size. It typically refers to the nominal opening size. For example, pure copper mesh screening 200 micron has 0.2 mm aperture size. From the mesh screen size chart, we can also figure out that the opening size of the 200 mesh copper screen is 0.0737 mm. So we can say its micron size is about 73.
What is 1 micron in mesh size?
1 micron in mesh size is the mesh screen has 1 micron (0.001 mm) nominal opening size.
Width: 1m or customized
Length / Roll: 30 m or customized
Packing: for one roll, usually, it’s packaged by moisture-proof paper. For many rolls, it’s packed by moisture-proof paper first, and then in a wooden cage.
Copper Mesh Screen Size Chart
What is the size of a wire mesh?
We also call the size of wire mesh as mesh size, mesh counts, mesh numbers. It means how many openings per inch or 25.4 mm. So for any one liner inch distant, the higher the mesh size, the more the quantity of holes, the smaller the size of the opening. And then the smaller the particle can pass through.
Please note: if we only know the mesh size, usually, we cannot confirm the needed mesh. Material, wire diameter and aperture size are also necessary. A drawing or a simple sketch is essential for deep processing products with special shape and size.
What size is 40 mesh?
It’s the mesh which has 40 openings per inch in both directions. Its wire diameter can be 0.254 mm. If so, the opening size will be 0.38 mm, and micron size is 380. Therefore, the mesh can save particles over 0.38 mm, and filter ones smaller than 0.38 mm.
How do I know my screen mesh size?
It’s simple to figure out the mesh size. You just need to know how many holes in an inch of your screen. Because the mesh size is the number of openings per inch.
If it’s a coarse mesh and there aren’t too many holes per linear inch, counting is a good choice. For example, #2 mesh screen has only 2 openings on both sides. 4 mesh screen size means the copper mesh screen has 4 openings in both directions.
But if it’s a fine mesh, it may be hard to count because of too many holes and too small hole size. For instance, we need to confirm if there are 200 holes per inch for a 200 mesh size screen. It’s very time-consuming. So how do you specify wire mesh size?
We can use tools to measure wire diameter and hole size firstly.
Then, calculating the mesh counts. How do you calculate mesh size?
Thickness of woven wire mesh is related to its wire diameter. The overall thickness is approximately equal to the warp wire diameter plus the weft / filling / woof wire diameter.
What is a fine mesh?
If the mesh size is over 80, we often say the screen is a fine mesh. Otherwise, it’s a kind of coarse mesh.
According to different requirements, we can customize copper wire mesh cloth with different shapes or specifications. For example
Good malleable / ductile
Good pliable / flexible
EMI and RFI shielding
Atmospheric corrosion resistance
Resistance to rust and also sparking
Beautiful appearance for decoration
What is copper wire mesh / screen used for?
Pure copper mesh screen is flexible, malleable, and excellent for electric and thermal conductivity.
Shielding: Pure copper mesh is also suitable for Faraday cages, MRI rooms, computer rooms, laboratories or other environments where you want to block EMI, RFI or others. That’s because it provides a safe barrier to protect from electromagnetic radiation. Usually, the higher the mesh count, the better the shielding ability. For example, 200 mesh fine copper mesh fabric blocked my cell phone signal.
Decorating: Copper wire mesh screen is suitable for decorating ceilings or be used as space partition, exquisite artworks because of its special color. It’s softer than a similar stainless steel wire mesh, and easy to cut with scissors. It can be bent to form complex shapes, but still maintain its strength. Moreover, it provides good corrosion resistance in weather or atmospheric conditions. For example, copper mesh roll can be used as copper window screens, insect screens, fireplace screens, gutter screens, copper screen door mesh, etc.
Electrical applications may use copper woven wire mesh because of its mechanical, thermal and electrical properties.
Wire mesh copper is also suitable for a variety of applications and industries, like aerospace, marine, military shelters, electric heaters, energy storage, insect screen/pest control screen, papermaking, etc.
Copper mesh fabric is suitable for filtering liquid, gas, solid, etc.
