List Of Alloys And Their Composition And Uses Pdf
An alloy is a mixture of two or more metals. Some familiar examples ofalloys include brass, bronze, pewter, cast and wrought iron, steel, coinmetals, and solder (pronounced SOD-der; a substance used to join othermetallic surfaces together). Alloys are usually synthetic materials,developed by scientists for special purposes. They generally havespecially desirable properties quite different from the metals from whichthey are made. As an example, Wood's metal is a mixture of about 50percent bismuth, 10 percent cadmium, 13 percent tin, and 27 percent leadthat melts at 70°C (160°F). This low melting point makesWood's metal useful as a plug in automatic sprinkler systems. Soonafter a fire breaks out, the heat from the flames melts the Wood'smetal plug, releasing water from the sprinkler system.

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.
