Pure copper is a material which is made of natural copper, there are also trace amounts of other elements so it cannot be said that pure copper is 100% copper. The approximation of natural copper in pure copper is 99.98%.
Copper wire mesh is a plain square weave wire mesh fabric. Excellent thermal and electrical conductivity and is easily soldered. Copper mesh is ductile and malleable, but not as strong as brass or stainless steel woven wire mesh.
Characteristics 
- a comprehensive selection of mesh counts
- pliable, malleable, and has high thermal and electrical conductivity
- able to easily bend, but still maintain its strength.
- 99+% commercially pure and is available in rolls and cut pieces
