An alloy is a mixture of two or more metals. Some familiar examples of alloys include brass, bronze, pewter, cast and wrought iron, steel, coin metals, and solder (pronounced SOD-der; a substance used to join other metallic surfaces together). Alloys are usually synthetic materials, developed by scientists for special purposes. They generally have specially desirable properties quite different from the metals from which they are made.

As an example, Wood's metal is a mixture of about 50 percent bismuth, 10 percent cadmium, 13 percent tin, and 27 percent lead that melts at 70°C (160°F). This low melting point makes Wood's metal useful as a plug in automatic sprinkler systems. Soon after a fire breaks out, the heat from the flames melts the Wood's metal plug, releasing water from the sprinkler system. Alloy Composition Uses Babbitt metal tin: 90% used in bearings because of its low measure of fricti with steel antimony: 7% copper: 3% bell metal copp 77% casting of bells tin: 23% brass copper with up to 50% zinc inexpensive jewelry; hose nozzles and couplings; piping; stamping dies bronze copper with up 12% tin coins and medals; heavy gears; tools; electrical hardware coin metal copper: 75% U.S.
Coins nickel duralumin aluminum: 95% aircraft, boats, railroad cars, and machinery because of its high strength and resistance to corrosion copper: 4% manganese. I hope you can help me. I bought some Jewelry 'findings' to make my own jewelry, but I noticed the package does not indicate what type of metal they are so I emailed the company. The reply I recieved? 50% brass and 50% iron.
I am nervous to use these since they are 'made in China' and wonder if there is anything potentially harmful in them, or if they may cause allergic reactions to some people with sensivity to certain metals. What is your take on the 50/50 combo they claim? Thank you so much!
