Brass strip (also known as bronze strip) is an alloy formed primarily of copper and zinc, which is very versatile and its properties depend on the ratio of copper to zinc. Brass containing more than 63% copper can be cold worked, annealed, and ductile, while alloys containing less copper and more zinc should be hot worked and have higher strength.
Copper-nickel-zinc alloy, commonly known as German silver because of its beautiful silver-white appearance, this alloy has high strength and corrosion resistance, good plasticity
silver cadmium oxide alloy is a silver-based alloy containing cadmium oxide, silver and cadmium oxide are immiscible. There are AgCdO5, AgCdO8, AgCdO10 and AgCdO15, etc.
