What Are the Types and Advantages of Copper Meshes

For more information, please visit Jiushen.

Copper mesh, often referred to as copper screen or copper wire mesh, consists of a square weave created using copper wires, which are renowned for their excellent electrical and thermal conductivity. Copper, being a malleable and soft material, has found extensive usage as electromagnetic interference protection. Additionally, it acts as a shield against radio frequency interference and serves as a window screen in various industries, including filtration and separation.

Due to their long service life and association with wealth and prestige, copper mesh is frequently utilized as a decorative facade material in construction projects. Furthermore, its robust nature makes it a reliable and durable reinforcement material for plastering ceilings and walls.

Classification

Copper meshes can be categorized into medium, fine, and coarse wire mesh, based on wire specifications. Medium copper mesh typically ranges from 12 x 12 to 40 x 40 meshes, while fine meshes include sizes such as 50 x 50, 60 x 60, 80 x 80, and 100 x 100. Coarse mesh sizes range from 2 x 2 to 10 x 10.

Moreover, copper mesh can also be subdivided into three types depending on the materials used: copper mesh, brass wire mesh, and phosphor copper mesh.

Purple copper mesh

Made from purple copper wire containing 99.8 percent pure copper, this mesh is non-magnetic and can withstand grinding pressures. It is commonly employed for filtering electron beams and in electronic display screens.

Brass wire cloth or brass wire mesh

This type consists of brass with varying proportions, such as 65 brass (65% copper and 35% zinc) and 80 brass (80% copper and 20% zinc). Brass wire cloth is non-magnetic, exhibits good ductility, and resists wear. It is used in applications involving porcelain glass, clay, liquid and gas filtration, and screening various granules.

Phosphor mesh

Also known as tin bronze mesh, phosphor mesh is composed of phosphor copper wire containing 85 to 90 percent copper and 5 to 15 percent tin. It is non-magnetic and can resist grind alkali, enhancing its ductility.

Mesh Sizes and Shape

Mesh sizes can vary, with wire diameters ranging between 0.3mm to 1.2mm. A common choice among consumers is a wire diameter of 0.6mm, while mesh openings typically measure between 4mm to 6mm. The mesh is generally square in shape, with a bare copper mesh spacing of 300 x 300mm.

Advantages of Copper Mesh

Tensile Endurance

Thanks to its strength and versatility, copper increases the reliability of systems, even under adverse conditions. A personal experience in a construction project illustrated how using copper mesh for reinforcement provided confidence in the overall integrity of the structure.

Non-Reaction with Water

Copper remains unaffected by water, though it may react with atmospheric oxygen, forming a protective layer of copper oxide. This layer helps prevent further deterioration, contrasting with iron, which succumbs to rust in moist conditions.

Adaptability

The flexibility of copper wire mesh allows for easy installation. It can be effortlessly attached through methods such as welding, brazing, or soft soldering, making it suitable for a range of configurations.

Durable and Maintenance-Free

Renowned for its durability, copper cable mesh demands minimal maintenance, making it an ideal choice for various mechanical and industrial applications. It does not require any finishing to avert corrosion.

Biostatic

Another appealing characteristic is that bacteria cannot proliferate on the copper grid, adding to its utility in hygienic applications.

Sustainability

Copper is recyclable and retains its high quality when repurposed, ranking as one of the most recyclable metals alongside aluminum and iron.

Safety and Security

Unlike other materials, copper cable mesh doesn't melt or combust easily, and it does not transmit fire through walls, ceilings, or floors. Moreover, it doesn't decompose into toxic gases, promoting a safer environment.
