  1. METALLICSTRUCTURALMATERIALS Nonferrous Metals and Alloys

  2. Prominent Features of Nonferrous Metals • Characteristic colour • Low melting temperature • Low hardness • High plasticity • Absence of polymorphic transformations

  3. Classification of Nonferrous Metals • Light: Al, Mg, Be, [ Ti ] • Low-melting: Sn, Pb, Zn, Bi • Noble: Au, Ag, Pt, [ Cu ] • Refractory: W, V, Nb, Zr, Ti

  4. Russian platinum coins of XIX century

  5. Aluminium Alloys W – wrought alloys, C – cast alloys, NS – alloys not strengthened by heat treatment, S – alloys strengthened by heat treatment

  6. Phase Diagram Al – Cu The eutectic consists of two phases: E = α + CuAl2.
