is strong, malleable, and ductile, and has high magnetic permeability. Cast
iron, which is iron alloyed with carbon, is brittle, less ductile than
iron, and must be cast in a mold.
Perfluoroalkoxy (PFA) is chemically inert, has high strength, and can
be used at a higher working temperature than most plastics.
Polyvinyl chloride (PVC) is corrosion resistant and
lightweight, and has high strength. It resists reactions with acids, gasoline,
alcohol, and hydrocarbons.
Stainless steel resists scaling and
Stainless steel 304 is corrosion resistant and withstands high temperatures.
a low carbon version of stainless steel 304, with slightly less tensile
Stainless steel 316 has more
corrosion resistance than stainless steel 304 because molybdenum has been added to the alloy. It may have slightly
higher magnetic permeability than
stainless steel 304. Sometimes 316 is called "marine grade
stainless steel" due to its resistance to chloride corrosion.
the low carbon version of stainless steel 316.
Steel is a general purpose material with better
weldability and more rust resistance than iron.
