a metallic element, occurring in cassiterite, that has several allotropes; the ordinary malleable silvery-white metal slowly changes below 13.2°C to a grey powder. It is used extensively in alloys, esp bronze and pewter, and as a noncorroding coating for steel. Symbol: Sn; atomic no: 50; atomic wt: 118.710; valency: 2 or 4; relative density: 5.75 (grey), 7.31 (white); melting pt: 231.9°C; boiling pt: 2603°C
Also called (esp US and Canadian): can. an airtight sealed container of thin sheet metal coated with tin, used for preserving and storing food or drink
any container made of metallic tin
to complete a home baking of cakes, biscuits, etc
Also called: tinful. the contents of a tin or the amount a tin will hold

slang money
it lives up to expectations
to put (food, etc) into a tin or tins; preserve in a tin
to plate or coat with tin
to prepare (a metal) for soldering or brazing by applying a thin layer of solder to the surface
A malleable, silvery metallic element that occurs in igneous rocks. It has a crystalline structure and crackles when bent. Tin is used as an anticorrosion agent and is a part of numerous alloys, including bronze. Atomic number 50; atomic weight 118.71; melting point 231.89°C; boiling point 2,270°C; specific gravity 7.31; valence 2, 4.

before 900; (noun) Middle English, Old English; cognate with Dutch, Old Norse tin, German Zinn; (v.) Middle English tinnen, derivative of the noun
Tin is a kind of metal that is soft and silver-colored. The most common use of tin today is in solder, the hot, liquid metal that holds pipes and other metal pieces together. You may think of common items like tin foil and tin cans when you contemplate the uses of tin. Actually, so-called tin cans and tins are made of steel or other metals that are coated in tin. Before the middle of the 20th century, the foil used for covering food was made of thin sheets of tin. It was stiffer than today's foil (which is made of aluminum), and left food with a metallic, "tinny" taste.
