Properties of Metals (Form part of the elements)

metals form part of the elements of nature, are undecompounded bodies, and distinguished from the other elements by their lustre, weight, &c. 3350. Table Showing, in their Order, the Comparative Properties of Metals.

Order of Malleability.

Gold, Silver, Copper, Tin, Cadmium, Platinum, Lead, Zinc, Order of Brittle- Dustility.

Gold, Silver, Platinum, Iron, Copper, Zinc, ness.

Antimony, Arsenic, Bismuth, Chromium, Cobalt, 3351. Lustre is so characteristic as to have formed the common expression "me tallic lustre." 3352. Weight is also a rough distinguish ing characteristic... 3353. Fusibility is a property common to all metals. Before some metals are rendered fluid by heat, they become pasty; such is an indication of malleability. The following table gives the degrees (Fahr.) of heat at which metals fuse:

Tin..

Bismuth Lead Zinc. 4420 407° ....... 612° 773° ..... 810° 1,873° 1,900° 2,010° 2,780° 2,800° (about) -3,000° (about) .......

Antimony ......

Tin, Manganese, Molybdenum, Silver.

Copper Lead, Gold..

Nickel, Titanium.

Nickel, Iron (Cast) Nickel.. ..

Palladium, Cadmium, Uranium, Manganese.

Iron, 60.000 40.000 66.000 34.000 83.400 8.300 20.000 2.000 81.000 16.000 60.000 17.800 22.200 50.000 13.600 19.300 50.000 25.000 80.200 20.000 Potassium, Tellurium, Palladium, Tungsten, Rhodium.

Order of Heat Order of Elec- Order of Tenacity. Conducting trical Conduct Power. ing Power.

Copper, Gold, Silver, Zinc, 3354. Malleability, or the property of being beaten out into thin plates without cracking or breaking, is common to several metals. 3355. Ductility is also a property found in some metals. It is allied to mallcability, and often confounded with it. It is the property of being drawn into wire. 3356. Tenacity, or the resistance of Platinum, being pulled asunder by the force of tension, Iron, 1,000 Gold, Copper, 550 Platinum, Platinum, 494 Silver, Silver, 349 Copper, Gold, 273 Iron, Zinc, Zinc, Iron, Tin, Tin, Tin, Lead, Lead, Lead, Mercury, varies exceedingly in metals. 3357. Brittleness, resulting from hardness, is a property also met with; and where the brittleness is not extreme, hardness is iu Potassium. favor where subjected to compression.
