EMF Shielding Fabric by Alfredx Copper Nickel Faraday Bolt 20 yd

Description

Product Overview

Alfredx EMF Shielding Fabric is engineered to meet the demanding requirements of modern environments where electromagnetic interference (EMI) can compromise the performance of sensitive equipment and the health of occupants. Constructed from a proprietary blend of 20% copper‑nickel alloy and 80% high‑tenacity polyester, the material delivers a consistent faraday cage effect across a broad frequency spectrum, from low‑frequency power line noise up to high‑frequency 5G cellular bands. The copper‑nickel fibers are woven in a tight twill pattern that maximizes conductivity while preserving the flexibility and drape of a traditional textile, allowing the fabric to be folded, rolled, or sewn without loss of shielding integrity. Each bolt of fabric measures 42 inches in width and is offered in three convenient lengths—3 yards (approximately 9 feet), 20 yards (60 feet), and 50 yards (150 feet)—providing scalable solutions for both small‑scale DIY projects and large‑scale industrial installations.

Performance testing conducted by independent labs confirms a shielding effectiveness of up to 95 dB across the 30 MHz to 3 GHz range, a level comparable to solid metal enclosures but with the added advantage of lightweight handling and easy integration into existing structures. The fabric is also designed for durability; it resists tearing, abrasion, and UV degradation, and it can be laundered on a gentle cycle without compromising its conductive pathways. Care instructions recommend machine or hand washing on low heat, avoiding bleach, and low‑temperature drying, ensuring that the material remains functional over many years of use. The product carries the UPC 012372334027 and is listed under model number NO.11, reflecting Alfredx’s commitment to traceable, high‑quality manufacturing.

Usage

In residential settings, the fabric can be applied to walls, ceilings, or window coverings to create a low‑cost shield against Wi‑Fi routers, smart‑meter emissions, and other household sources of electromagnetic radiation. Homeowners concerned about the cumulative exposure from multiple devices can line closets, create custom curtains, or wrap electronic enclosures with the material to reduce signal penetration. In office environments, the fabric is ideal for protecting confidential data by preventing unintended wireless leakage from conference rooms, server racks, or workstations. By covering cable trays, conduit, or even entire workstations, businesses can meet compliance standards for electromagnetic compatibility (EMC) while maintaining an aesthetically neutral appearance.

Laboratory and industrial applications benefit from the fabric’s ability to create controlled EMI‑free zones. Researchers can line the interiors of test chambers, shield sensitive instrumentation, or construct portable Faraday cages for field measurements. The material’s flexibility allows it to conform to irregular shapes, making it suitable for wrapping equipment such as oscilloscopes, spectrum analyzers, or medical devices that require protection from ambient RF noise. Additionally, the fabric’s resistance to chemicals and its washable nature make it a practical choice for environments where regular cleaning is mandatory, such as clean rooms or manufacturing floors.

Why Choose Us

Alfredx’s manufacturing process adheres to strict quality control protocols, including continuous monitoring of fiber conductivity, weave uniformity, and dimensional accuracy. Each batch of EMF Shielding Fabric undergoes a series of electrical resistance tests to verify that the copper‑nickel content meets the specified 0.1 Ω/square target, ensuring consistent shielding performance across the entire roll. The company also holds ISO 9001 certification for its production facilities, underscoring a systematic approach to product reliability and customer satisfaction.

Beyond the material itself, Alfredx provides comprehensive support to help customers integrate the fabric into their projects. A dedicated technical assistance team is available to answer questions about installation methods, compatibility with other materials, and performance optimization. The company offers a one‑year limited warranty covering defects in material and workmanship, and it provides replacement options for any portion of the fabric that fails to meet the advertised shielding specifications. Detailed installation guides, cutting templates, and case studies are accessible through the Alfredx website, empowering users of all skill levels to achieve professional results.

FAQ

What frequency range does the fabric effectively block?

The fabric provides shielding performance from 30 MHz up to 3 GHz, covering most common sources of electromagnetic interference including Wi‑Fi, Bluetooth, cellular, and emerging 5G frequencies.

Can the fabric be used outdoors?

Yes, the material is UV‑resistant and can be installed in outdoor environments such as garden sheds, patio enclosures, or vehicle interiors. For prolonged exposure, it is recommended to apply a protective coating to extend longevity.

How does the fabric affect signal strength inside a shielded area?

When properly installed, the fabric attenuates external signals by up to 95 dB, effectively creating a Faraday cage. This reduction is sufficient to prevent most wireless devices from communicating through the shielded barrier, while still allowing wired connections to function normally.

Is the fabric compatible with standard sewing equipment?

The fabric can be cut with scissors or rotary cutters and sewn using a heavy‑duty needle (size 90/14 or larger). It works well with both industrial sewing machines and home‑sewing kits, though a polyester thread is recommended to maintain durability.

What care instructions should I follow to preserve shielding performance?

Wash the fabric on a gentle cycle with cold water, avoid bleach, and tumble dry on low heat. If ironing is needed, use a low‑temperature setting and place a protective cloth between the iron and the fabric to prevent direct heat exposure.
