Metals are the largest category of elements and they are characterized by their appearance: usually they possess a silvery shine, they are solid (except for mercury), they are malleable and they conduct electricity and heat. Transition metals are the elements that belong to the middle of the periodic table.

Today, most nickel is obtained from the mineral pentlandite (NiS·2FeS). ... Nickel is also used to manufacture some types of coins and batteries. Nickel is alloyed with other metals to improve their strength and resistance to corrosion. Nickel is alloyed with steel to make armor plate, vaults and machine parts.

A silvery metal that resists corrosion even at high temperatures. Nickel resists corrosion and is used to plate other metals to protect them. It is, however, mainly used in making alloys such as stainless steel. Nichrome is an alloy of nickel and chromium with small amounts of silicon, manganese and iron.

Nickels minted in the United States between 1942 and 1945 are made of 35% silver. ... Normally all other nickels are composed of 75% copper and 25% nickel. Due to the pressing need for industrial metals like nickel during World War II, five-cent coins were actually made from 35% pure silver during the duration of the war.

What kind of metal is used in the making of Plunder jewelry? Most of our jewelry is made up of a composite metal. Our jewelry is lead-free, however we cannot claim that all of our jewelry is nickel-free. We have stainless steel and acrylic products and you can find descriptions online of those products.
