China Copper Foil Shielding & RF Shielded Doors factories

Aluminum Foil Rfid Shield

Product Details: Aluminum foil can be used as a makeshift RFID shield by wrapping it around cards or wallets. It works by interfering with RFID signals due to its conductive properties, which convert electromagnetic waves into thermal energy and partially reflect or refract the waves.

Pros:
– Inexpensive and easily available
– Temporary and effective in reducing the effectiveness of card readers
– Can prevent reading information from long distances

Cons:
– Does not block RFID signals entirely, only interferes with them
– Not durable and can crease or tear easily
– Aesthetically unappealing when used as a wrap for cards or wallets
– Not a foolproof protection method

Aluminum Foil Conductive Adhesive Tape For EMI Shielding

Frequently Asked Questions (FAQs)

Frequently Asked Questions About Aluminum Foil Shield Factories in China

What types of aluminum alloys are commonly used for cable shielding foil in Chinese factories?

Chinese factories often use aluminum alloys such as 8011, 1235, and 8079 for cable shielding foil. These alloys are chosen for their excellent mechanical properties, corrosion resistance, and ability to provide effective shielding.

How is aluminum foil for cable shielding produced?

The production involves rolling sheet ingots cast from molten aluminum and then re-rolling them to the desired thickness. The foil may also be coated with a plastic film on one or both sides to form an aluminum-plastic composite foil, which enhances its shielding properties.

What are the typical specifications for aluminum foil used in cable shielding?

Typical specifications include thicknesses ranging from 0.005mm to 0.2mm, widths from 10mm to 1600mm, and various tempers such as O, H18, and H24. The foil usually has one bright side and one matte side, and it is packaged in free fumigated wooden boxes.

How do Chinese factories ensure the quality of their aluminum foil products?

Chinese factories, such as those in Anyang City, Henan Province, rely on independent research and development, imported equipment, and strict quality control measures. They ensure minimal oil on the surface, no holes, and strict control of pinholes, resulting in products that exceed national standards.

What is the typical delivery time and payment terms for ordering aluminum foil from Chinese factories?

The typical delivery time is around 25-35 days after receiving the prepayment. Payment terms often include 30% advance payment via Telegraphic Transfer (T/T) and 70% balance upon shipment, or through Letter of Credit (LC). The exact terms can be negotiated with the supplier.
