Alloy: 101 | Material: Copper | Shape: Sheet | Thickness: 0.04 Inches | Item Width: 36 Inches | Item Length: 36 Inches Copper Sheet 101 offers exceptional electrical and thermal conductivity, high ductility, and corrosion resistance. 101 is a commercially pure grade that is oxygen free, and it is immune to hydrogen embrittlement at elevated temperatures. It is typically used in conductors, wiring, and particle accelerators. Copper is a reddish metal with a face-centered cubic crystalline structure. It reflects red and orange light and absorbs other frequencies in the visible spectrum, due to its band structure, so it as a nice reddish color. It is malleable, ductile, and an extremely good conductor of both heat and electricity.
