Metal Alloy is a metal made by combining two or more metallic elements, base metals, to give greater strength or resistance to corrosion. In mining and economics, base metals refer to industrial non-ferrous metals excluding precious metals, like silver, gold, and platinum. Base Metals include copper, aluminum, nickel, tin, zinc antimony, bismuth, lead and many more. Metal Alloy, also known as Pewter and is usually a tin based alloy 85-95% of the time but could also be zinc based.
In December of 1994, The US Safe Drinking Water Act defined Lead-free as having less than 0.25% lead content. Most newly made solid pewter on the market today is considered lead free by these standards. But it is still recommended to not give children Metal Alloy jewelry if there is any chance, they will put it in their mouths!
