Pure Copper Mesh Screen
Pure copper mesh screen is a metal mesh made from 99.9% pure copper wire or sheet, known for its excellent electrical and thermal conductivity, corrosion resistance, and antimicrobial properties. It is used in a variety of industrial, commercial, and decorative applications where conductivity, shielding, or filtration is required.
Pure copper screen mesh can be manufactured in various forms such as woven, knitted, expanded, or perforated depending on the intended use. Pure copper's natural reddish-gold color also makes it suitable for artistic and architectural applications. It is easy to fabricate, bend, and solder, making it a popular choice for applications involving EMI/RFI shielding, insect screening, battery production, chemical filtration, and grounding.
Types of Copper Screen Mesh
Pure copper screen mesh screens are available in several types based on their manufacturing methods and patterns:
Woven Copper Mesh Screen: Made by weaving copper wires in plain or twill weave patterns. Commonly used for insect screens, filtration, and EMI shielding.
Knitted Copper Mesh: Made by looping fine copper wire into a mesh similar to fabric. Offers elasticity and is commonly used for gas-liquid filtration, demisters, and Faraday cages.
Expanded Copper Mesh Screen: Created by slitting and stretching copper sheets into diamond-shaped openings. Lightweight, durable, and used in speaker grilles, battery electrodes, and shielding panels.
Perforated Copper Screen Mesh: Made by punching holes into copper sheets in various patterns (round, square, slotted). Offers decorative appeal along with functionality for ventilation, sunshading, and filtration.
Features and Applications
Electromagnetic Interference (EMI) and Radio Frequency Interference (RFI) Shielding: Used in electronics enclosures, cable shielding, and Faraday cages to prevent signal interference and data leakage.
Insect Screens: Durable and corrosion-resistant copper mesh is ideal for window and door screens, especially in coastal or humid environments.
Filtration and Separation: Used in the chemical, food, and pharmaceutical industries to filter liquids and gases, thanks to its fine mesh and non-reactive surface.
Architectural and Decorative Applications: With a natural reddish metallic sheen, copper mesh is popular for ceiling panels, wall coverings, lighting fixtures, and art installations.
Grounding and Static Discharge Applications:
Utilized in antistatic mats, grounding straps, and electrical safety equipment.
Demisters and Mist Eliminators: Knitted copper mesh helps remove mist and liquid droplets from gas streams in industrial processing.
Stuff-It for Gaps and Holes: Copper mesh is stuffed into holes, gaps, and vents in walls, roofs, and pipes to block unwanted airflow or prevent access.
Pest and Rodent Control: Often used to seal entry points against mice, rats, birds, bats, snails, and other pests. It is difficult for animals to chew through, yet flexible enough to mold into small openings.
