Aluminum and stainless steel have their own advantages and disadvantages when being used in a
cooking appliance. The best pressure cooker is made from a combination of the materials as they allow
you the best of both worlds.
Aluminum has a better "strength to weight" ratio. In other words, while it is not as strong as steel, the
fact that it weighs less than half as much makes up for its lower strength. This is why most airplanes are
made of aluminum.
Aluminum is generally more corrosion resistant than all but the most expensive stainless steels.
However under certain condition it may corrode rapidly with catastrophic results.
Aluminum is usually less expensive than stainless steel (SS), though it is 2-4 times more expensive than
ordinary (non-stainless) steels.
Aluminum is fairly soft and easier to cut, saw, carve, drill, and machine than steel. A key will scratch
aluminum much more readily than stainless steel.
Aluminum is an excellent conductor of heat. This is why it's used for car
