  Copper  \Cop"per\,  n.  [OE.  coper  (cf.  D.  koper,  Sw  koppar  Dan. 
  kobber,  G.  kupfer),  LL  cuper,  fr  L.  cuprum  for  earlier 
  Cyprium  Cyprium  aes,  i.e.,  Cyprian  brass,  fr  Gr  ?  of 
  Cyprus  (Gr.  ?),  anciently  renowned  for  its  copper  mines.  Cf 
  {Cypreous}.] 
  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.

  of  made  or  consisting  of  copper,  or  resembling  copper; 
  as  a  copper  boiler,  tube,  etc

  From  Easton's  1897  Bible  Dictionary  [easton]: 
 
  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).
