What is the difference between copper foil tape and aluminum foil tape

Aluminum Foil Tape consists of high quality pressure sensitive adhesive and aluminum foil, the base material is more than 99.95% pure aluminum foil.
Aluminum foil tape has good adhesion, strong adhesion, anti-aging and other effects. Specifications (0.05mm-0.08mm) various widths and lengths, is the main raw material accompanying the refrigerator and freezer, but also one of the necessary materials for the distribution of heat preservation materials。This product is widely used in refrigerators, air aprons, automobiles, petrochemicals, bridges, hotels, for all kinds of transformers, cell phones, computers, PDAs, PDP, LED displays, laptop computers, photocopiers, and other electronic products in need of electromagnetic shielding place.

These two materials are not the same material, the color is also very different. Performance is also a lot of difference, copper relative to aluminum, better conductivity. The shielding performance of copper foil tape is also better than aluminum foil. However, the width of aluminum foil tape can be 1m, while copper foil tape is only 600mm.

Due to its lightweight and heat-insulating properties, aluminium foil tape is commonly used in the HVAC field for pipe wrapping, duct connection and fixing of heat-insulating materials. Copper foil tape is commonly used in the electronics field, such as circuit board shielding, cable shielding, grounding conductive, and so on.

Copper foil tape price will be much more expensive than aluminum foil tape. Because their base materials are not the same, copper is more expensive than aluminum.

If the customer requirements are not high, choosing aluminum foil tape will be better. If the product is considered fine, to be more breakthrough must choose copper foil tape.
