1. Types Of Metal

2. Pure metals -Single element metal -Mined from the ground -Natural metal -Examples -Copper, lead, aluminum, iron, tin, gold, silver, titanium, nickel, platinum, tungsten, etc.

3. Alloy metals -Mixture of metals -Examples -Brass -Bronze -Steel -Non Ferrous -Contains no iron -Ferrous -Contains Iron

4. Non Ferrous (No Iron) -Aluminum-Al -Pure or alloy -Low melting point (1100’F) -Corrosion Resistant -Light weight -Hard to weld (TIG welding) DO NOT GRIND!!!

5. Copper-Cu -Pure or alloy -Soft -solders well -conducts heat and electricity well -Easy to work

6. Brass -Alloy (copper and zinc) -Solders well -Harder metal

7. Bronze -Alloy (copper and tin) -Solders and brazes well -Used in casting

8. Lead-Pb -Low Melting point (600’F) -Soft (Easy to hammer and shape) -Heavy metal -Poisonous Fumes

9. Ferrous Metals (Iron)-Fe -Cast iron -Heavy -Hard to work -Hard to weld

10. Wrought iron -Easy to work -Welds well -Expensive

11. Mild Steel -Easy to work -Welds well-Brazes well -Strong -Economical

12. Galvanized Steel -Mild steel -Has Galvanized coating -Solders well

13. Stainless Steel -Expensive -Corrosion resistant -Hard to weld -Hard to work
