1. Non-Ferrous Alloys Chapter 13

2. Non-ferrous Alloys Predate Iron Many non-ferrous alloys can be produced at lower temperatures than iron Copper, brass, and bronze all predate iron alloys

3. Aluminum Alloys Refined by electrolytic reduction of aluminum oxide Requires a lot of electricity Easy to form and light weight Work hardens well Easy to recycle Oxidation coating

4. Magnesium Alloys Electrolytically extracted from sea water! (And the Great Salt Lake) HCP structure leads to brittle properties Does not strain harden well (its already brittle) Magnesium-Aluminum alloys are strong and light weight

5. Beryllium Alloys Very light weight Brittle (HCP) Chemically reactive and toxic

6. Copper Some native copper exists (metallic copper) Usually refined from copper oxide FCC gives it good ductility Poor strength Work hardens well Pure copper has high electrical conductivity

7. Brass and Bronze Copper Zinc alloys are called brass Copper Tin alloys are called bronze Both are solid solution strengthened

8. Other Copper Alloys Precipitation hardened with Zirconium Chromium Beryllium Lead is added to improve machinability

9. Copper – Aluminum alloys Aluminum Brass Have a wide variety of properties The copper-aluminum phase diagram has a eutectoid Martinsite transformation

10. Other Non-Ferrous Alloys Nickel – (including Monel) Titanium (HCP) Refractory metals – high melting points
