 10,000BC- Hunting and gathering
communities formed stone tools
and blades
 6000BC- Stone Age men learned to
fashion gold into jewelry
 4200BC- Silver is used as a basis
for monetary systems in Roman
and Chinese empires
 3500BC- Lead smelting begins
 750BC- Mercury discovered in
Egyptian tombs
 1791- Titanium is discovered but it
is not until the 1940’s that it is
used in structures
 1827- Aluminum is found to be the
most common metal in the Earth’s
crust and is one of the lightest of
all the metals
Ferrous Metal
-Cast Iron
-Wrought Iron
-Steel
-Stainless Steel
Nonferrous
Metal
-Aluminum
-Zinc
-Copper
-Brass
-Bronze
-Chromium
-Silver
-Nickel
-Pewter
-Titanium
 Depending on application
 Includes fasteners, decorative
attachments, and metal hardware
Sheets
Plates
Cast Forms
Pipes and Tubes
Extruded
Spun
Welding & Soldering
Weaving
Sheets
-Cannot be used structurally
-Flat sheets
-Stamped sheets
Plates
-Sheets that can be used
structurally
Cast Forms
-Pouring molten metal into a
mold
Pipes and Tubes
-Round profile
-Square profile
Extruded
-Works like a cookie cutter
Spun
-Spins on rotating drive called a
lathe
Welding
-2 pieces of metal fused together
without a metal filler
Soldering
-2 pieces of metal fused together
with a metal filler or adhesive
Weaving
-Produces a surfacing or screening
material
Refers to the texture
Shininess of metal varies
 Bright
 Buffed
 Brushed
 Matte
 Etched
 Properly protected metal needs
very little maintenance
 Many metal items can be cleaned
with glass cleaner unless
otherwise specified
Plating
-applying one metal to another by
electrolysis, hot dipping, or
electroplating
Coatings/Anodizing
-applying one metal to another by
sitting on the surface rather than
integrating into the body of the
metal
Salvaged Metal
-cast metal is most popular, there
is an overabundance
Alloys
-harder to recycle
-cannot predict properties if
recasted
-initially more expensive in cost
and environmental impact to
extract and process
 Custom is more expensive than
stock items
 There are options within
manufacturers standards for finish,
sizes, and details
 More steps in installation means a
higher cost
