Is your all copper lamp product pure copper?

Q: Is your all-copper lamp product pure copper? A: Strictly speaking, there is no such thing as pure copper. The copper used in civilian products belongs to alloy copper. Copper is smelted together with different metals, and its physical properties vary greatly. Brass is a copper-zinc alloy, which is called brass because its exterior color is yellow. Because it has good ductility and plasticity, and has certain structural force, it should be widely used in the manufacturing field of all copper lamps and other products.
