Ecuadorian Alpaca Silver Jewelry is Made From an alloy of zinc, iron and nickel. It has properties like stainless steel but very light weight material that will not tarnish. Alpaca Silver Jewelry products are hypo-allergenic and extremely lightweight material. Some of the Alpaca Silver Jewelry semi-precious stones used are Agate, Red Jasper, Onyx, Rose Quartz and Celestine - Other materials can be Murano Glass, beads and seeds, Cat's Eye beads, various colored beads, and a range of Paiche fish scales.
Many alloys fall within the general term of "nickel silver". All contain copper and nickel, while some formulations may additionally include zinc, antimony, tin, lead or cadmium. A representative industrial formulation, Alloy No. 752, is 65% copper, 18% nickel, and 17% zinc. In metallurgical science, such alloys would be more properly termed nickel brass. The white alloy of 75% copper and 25% nickel used in coins, such as the United States nickel, is better known as copper-nickel, cupro-nickel or cupronickel. Some nickel silver alloys, especially those containing high proportions of zinc, are stainless (corrosion-resistant). Nickel silver alloys are commonly named by listing their percentages of copper and nickel, thus "nickel silver 55-18" would contain 55% copper, 18% nickel, and 27% other elements, most probably entirely zinc. A two-element alloy may be named for its nickel content alone, thus NS-12 is 88% copper and 12% nickel. |
