note: copper is the only metal which occurs native abundantly in large masses; it is found also in various ores, of which the most important are chalcopyrite, chalcocite, cuprite, and malachite. copper mixed with tin forms bell metal; with a smaller proportion, bronze; and with zinc, it forms brass, pinchbeck, and other alloys.

Copper is one of the most important metals. Copper is reddish with a bright metallic lustre. It is malleable, ductile, and a good conductor of heat and electricity (second only to silver in electrical conductivity). Its alloys, brass and bronze, are very important. Monel and gun metals also contain copper. Apparently the reason that policemen in the USA are nicknamed "cops" or "coppers" is to do with their uniforms which used to have copper buttons. The most important compounds are the oxide and the sulphate, (blue vitriol).

English Wikipedia - The Free Encyclopedia
Copper is a chemical element with symbol Cu (from ) and atomic number 29. It is a soft, malleable and ductile metal with very high thermal and electrical conductivity. A freshly exposed surface of pure copper has a reddish-orange color. It is used as a conductor of heat and electricity, as a building material, and as a constituent of various metal alloys.

Easton's Bible Dictionary
derived from the Greek kupros (the island of Cyprus), called "Cyprian brass," occurs only in the Authorized Version in Ezra 8:27. Elsewhere the Hebrew word (nehosheth) is improperly rendered "brass," and sometimes "steel" (2 Sam. 22:35; Jer. 15:12). The "bow of steel" (Job 20:24; Ps. 18:34) should have been "bow of copper" (or "brass," as in the R.V.). The vessels of "fine copper" of Ezra 8:27 were probably similar to those of "bright brass" mentioned in 1 Kings 7:45; Dan. 10:6. Tubal-cain was the first artificer in brass and iron (Gen. 4:22). Hiram was noted as a worker in brass (1 Kings 7:14). Copper abounded in Palestine (Deut. 8:9; Isa. 60:17; 1 Chr. 22:3, 14). All sorts of vessels in the tabernacle and the temple were made of it (Lev. 6:28; Num. 16:39; 2 Chr. 4:16; Ezra 8:27); also weapons of war (1 Sam. 17:5, 6, 38; 2 Sam. 21:16). Iron is mentioned only four times (Gen. 4:22; Lev. 26:19; Num. 31:22; 35:16) in the first four books of Moses, while copper (rendered "brass") is mentioned forty times. (See BRASS.) We find mention of Alexander (q.v.), a "coppersmith" of Ephesus (2 Tim. 4:14).
Smith's Bible Dictionary

Heb. nechosheth, in the Authorized Version always rendered "brass," except in (Ezra 8:27) and Jere 15:12 It was almost exclusively used by the ancients for common purposes, and for every kind of instrument, as chains, pillars, lavers and the other temple vessels. We read also of copper mirrors, (Exodus 38:8) and even of copper arms, as helmets, spears, etc. (1 Samuel 17:5,6,38; 2 Samuel 21:16)

Essential mineral that is a component of several important enzymes in the body and is essential to good health. Found in all body tissues. Copper deficiency leads to a variety of abnormalities, including anemia, degeneration of the nervous system, skeletal defects, pronounced cardiovascular lesions, reproductive failure, elevated cholesterol, impaired immunity and defects in the pigmentation and structure of hair. Copper is involved in iron incorporation into hemoglobin. It is also involved with vitamin C in the formation of collagen and the proper functioning in central nervous system. More than a dozen enzymes have been found to contain copper. The best studied are superoxide dismutase (SOD), cytochrome C oxidase, catalase, dopamine hydroxylase, uricase, tryptophan dioxygenase, lecithinase and other monoamine and diamine oxidases. Plant sources are: Currants, Legumes, Mushrooms, Nuts and Raisins
