Tinned copper braided sleeving braided from tin-coated copper, it is both flexible and strong, with superior EMI protection.Tin coated can provide high conductivity,strong fatigue resistance and prevent the copper from oxidizing which would produce copper rust,causing poor contact.

It meets Meets QQ-B-575B standard,conforms to ASTM-B 33,with high performance of EMI, RFI, ESD Protection.

Copper braid sleeve ideal for shielding wire from EMI/RFI .Can also be ground staps,blocks electrical interference,shielding for signal wires,coax and audio cables,maintain signal stability and reduce signal noise,can also use for an rf ground.reduce hum in guitars,stop an electrical whine in car stereo.

And what is the emi/rfi attenuation rating of tinned copper braided sleeving?

Tinned copper braided sleeving has has excellent electrical conductivity and provides excellent current transmission. Wide, flat braided sleeves increases surface area, with fine braid density and a flat, smooth, burr-free surface for reliable connections to metal. Extruded width, thickness and resistivity are up to standard, long service life, safe and reliable. It provides superior attenuation of greater than 60 dB over wide frequencies, ranging from a few kilohertz (kHz) to several gigahertz (gHz).
