1. A common metal of a reddish color, both ductile and
malleable, and very tenacious. It is one of the best
conductors of heat and electricity. Symbol Cu. Atomic
weight 63.3. It is one of the most useful metals in
itself, and also in its alloys, brass and bronze.
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.
2. A coin made of copper; a penny, cent, or other minor coin
of copper. [Colloq.]

Copper : 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).
