used in a wide variety of alloys; found in stibnite atomic number 83, Bi, bismuth - a heavy brittle diamagnetic trivalent metallic element (resembles arsenic and antimony chemically); usually recovered as a by-product from ores of other metals atomic number 48, cadmium, Cd - a soft bluish-white ductile malleable toxic bivalent metallic element; occurs in association with zinc ores atomic number 20, Ca, calcium - a white metallic element that burns with a brilliant light; the fifth most abundant element in the earth's crust; an important component of most plants and animals atomic number 58, Ce, cerium - a ductile gray metallic element of the lanthanide series; used in lighter flints; the most abundant of the rare-earth group atomic number 55, caesium, cesium, Cs - a soft silver-white ductile metallic element (liquid at normal temperatures); the most electropositive and alkaline metal atomic number 27, cobalt, Co - a hard ferromagnetic silver-white bivalent or trivalent metallic element; a trace element in plant and animal nutrition atomic number 29, copper, Cu - a ductile malleable reddish-brown corrosion-resistant diamagnetic metallic element; occurs in various minerals but is the only metal that occurs abundantly in large masses;

"brass is an alloy of zinc and copper"mixture - (chemistry) a substance consisting of two or more substances mixed together (not in fixed proportions and not with chemical bonding) heavy metal - a metal of relatively high density (specific gravity greater than about 5) or of high relative atomic weight oreide, oroide - alloy of copper and tin and zinc; used in imitation gold jewelry Alnico - trade name for an alloy used to make high-energy permanent magnets; contains aluminum and iron and nickel plus cobalt or copper or titanium amalgam, dental amalgam - an alloy of mercury with another metal (usually silver) used by dentists to fill cavities in teeth; except for iron and platinum all metals dissolve in mercury and chemists refer to the resulting mercury mixtures as amalgams fusible metal - an alloy with a low melting point and used as solder and in safety plugs and sprinkler fuses pewter - any of various alloys of tin with small amounts of other metals (especially lead) pinchbeck - an alloy of copper and zinc that is used in cheap jewelry to imitate gold pot metal - an alloy of copper and lead used especially for making large pots solder - an alloy (usually of lead and tin) used when melted to join two metal surfaces white gold - a pale alloy of gold usually with platinum or nickel or palladium type metal - an alloy of tin and lead and antimony used to make printing type babbitt, Babbitt metal - an alloy of tin with some copper and antimony; an anti-friction lining for bearings Carboloy - an alloy based on tungsten with cobalt or nickel as a binder; used in making metal-cutting tools steel - an alloy of iron with small amounts of carbon; widely used in construction; mechanical properties can be varied over a wide range cheoplastic metal - any low-fusing alloy used in cheoplasty (molding artificial teeth) Inconel - a nickel-base alloy with chromium and iron; used in gas-turbine blades Invar - an alloy of iron and nickel having a low coefficient of thermal expansion; used in tuning forks and measuring tapes and other instruments pyrophoric alloy - an alloy that emits sparks when struck or scratched with steel; used in lighter flints shot metal - an alloy that is 98% lead and 2% arsenic; used in making small shot primary solid solution, solid solution - a homogeneous solid that can exist over a range of component chemicals; a constituent of alloys that is formed when atoms of an element are incorporated into the crystals of a metal Stellite - a cobalt-base alloy with chromium and other metals; very hard; used to make cutting tools and for surfaces subject to heavy wear tambac, tombac, tombak - an alloy of copper and zinc (and sometimes arsenic) used to imitate gold in cheap jewelry and for gilding | | | Verb | 1. | metal - cover with metalcoat, surface - put a coat on; cover the surface of; furnish with a surface; "coat the cake with chocolate" | | | Adj. | 1. | metal - containing or made of or resembling or characteristic of a metal; "a metallic compound"; "metallic luster"; "the strange metallic note of the meadow lark, suggesting the clash of vibrant blades"- Ambrose Biercenonmetal, nonmetallic - not containing or resembling or characteristic of a metal; "nonmetallic elements" | |
