  2. Sulam on: • mitme metalli või • metalli ja mittemetalli kokkusulatamisel saadud materjal

  3. Sulamite eelised võrreldes puhaste metallidega: • odavamad • kõvemad • tugevamad • madalama sulamistemperatuuriga • kuumakindlamad • vastupidavamad • korrosioonikindlamad

  4. Rauasulamid: • malm (2-5% C) • teras (kuni 2% C) • roostevabateras (lisandiks Cr)

  5. Vasesulamid: • pronks (Cu - Sn) • melhior (Cu - Ni) • messing ehk valgevask (Cu - Zn) • uushõbe ehk alpaka (Cu - Ni - Zn)

  6. Alumiiniumisulamid: • duralumiinium (Al - Cu - Mg - Mn) • silumiin (Al - Si)

  7. Kulla- ja hõbedasulamid: • kullasulamid ( Au - Cu, Au - Ag) • hõbedasulamid (Ag -Cu)
