Import 3oz Ed Copper Foils For Shielding Mri Cage — Buy in wholesale FOB from Supplier in China

BeiJing CN-FT JOVI Technology & Trading Co., Ltd supplies 3oz ED copper foils engineered for electromagnetic shielding in MRI cage construction, manufactured from Electrolytic Tough Pitch (ETP) Copper C11000 with a minimum copper purity of 99.9%. The 3oz nominal weight corresponds to approximately 105 micrometers thickness, a standard metric for heavy-gauge copper foil used in RF attenuation applications. Each roll is produced to ASTM B152 standards, the recognised specification for copper sheet, strip, plate, and rolled bar. This material is specifically sourced by medical facility contractors and shielding specialists for installation in diagnostic imaging suites where electromagnetic interference must be minimised below equipment-specific thresholds.

The ETP copper composition provides the electrical conductivity required for effective Faraday cage performance, with typical volumetric conductivity of 100% IACS at 20°C in the annealed condition. The electrolytic deposition process yields a fine, uniform grain structure that supports consistent forming and adhesion when applied to enclosure substrates. Surface finish is typically smooth on both sides for the shielding grade, with standard width options of 610mm, 1000mm, or 1220mm typical for architectural shielding rolls. Thickness tolerance for 3oz foil is typically plus or minus 5% under ASTM B152, though buyers should request the supplier's actual mill certificate for deviation values. The material is supplied in continuous rolls with core diameters suited to mechanical feeding during installation.

Primary applications include MRI room shielding, RF enclosure lining for telecommunications facilities, and electromagnetic compatibility (EMC) chambers in electronics testing. Buyers typically specify copper foil for shielding effectiveness at frequencies from 1 MHz to 10 GHz, with attenuation performance dependent on seam overlap and grounding methodology. For import procurement from China, confirm whether BeiJing CN-FT JOVI Technology & Trading Co., Ltd provides mill test certificates with chemical analysis, whether the material is supplied in annealed or as-rolled temper, and what roll lengths and core sizes are held in stock. Packaging for ocean freight typically involves moisture-barrier wrapping on wooden pallets; verify pallet dimensions and gross weight for container loading calculations.

BeiJing CN-FT JOVI Technology & Trading Co., Ltd is located in Shijing Shan District, Shixing Street, Beijing 100041, China, operating as an imported-tier supplier with harbor trust classification. The supplier's profile shows a response rate of 0.00% with zero average response hours, indicating no recorded buyer engagement through the platform. No verification status, employee count, annual revenue, or factory ownership details are provided in the available data. The company is positioned as a technology and trading entity, suggesting potential intermediary or distributor involvement rather than direct mill production.

The listing presents BeiJing CN-FT JOVI Technology & Trading Co., Ltd as offering ED copper foils for medical infrastructure shielding, with emphasis on ASTM B152 compliance and roll-form supply. Buyers should note that the response metrics suggest limited platform activity, and direct communication channels should be established before placing orders. The supplier's address in Beijing places it within China's capital region logistics network, though this does not imply manufacturing location. No ISO certification details, client references, or production capacity figures are stated in the profile and should be requested directly.
