Our High Quality Network Cables:
Bare Copper Wire

Their Poor Quality Network Cables:
Copper Clad Aluminum Wire CCA

Hold your knife at a 90 degree angle and begin scraping the copper off the cable. You will see silver (aluminum) Also Copper Clad Aluminum will break if you twist it several times on itself, where bare copper will typically hold on after you've twisted it 20-30 times.
