Brass is an alloy of copper and zinc. The proportions of zinc and copper can be varied to create a range of brasses with varying properties. For jewelry, the most commonly used percentages of copper and zinc is 67% and 33%. This mixture helps the brass become stronger and more durable than copper alone, which allows for superb electroplating quality, and thus, it is the perfect combination for fashion jewelry.
Plating:Galvanic Plating, Two-Tone
Galvanic Plating is a process that uses electric currents applied to two opposite poles (negative & positive) in a tank of solution which contains the dissolved material of the coating. The product is attached to the negative pole and powered with a negative charge, while the metal dissolved in the solution is powered with a positive charge. The product then attracts the positive-charged metal in the solution, and thus, creating a thin coating of the desired material.
Two-Tone is when a piece of jewelry has two types/colors of plating.
