What are the differences between stainless steel and aluminium
WHAT ARE THE
Choosing between aluminium and stainless
steel is one such dilemma that needs to be have
several considerations placed upon it before
making a decision. While to the layperson they
may appear similar, there are a number of key
differentiators between the two materials.
Here’s some of the more notable ones.
ALUMINIUM IN THE AIR
Ever wanted to know why most aircraft are made with an
aluminium base? It’s because aluminium offers a fantastic
strength to weight ratio over stainless steel. The material is
solid enough to withstand the tremendous pressures of air
travel, yet light enough to make it possible in the ﬁrst place.
Another transport-related purpose that aluminium is used for
is in the construction of car radiators and air conditioning
units. This is because aluminium triumphs over stainless
steel when it comes to thermal conductivity, which allows
cooling and heating systems to be more effective.
FOOD FOR THOUGHT
Another industry that most people may not think about is
food transport. Stainless steel has been found to be less
reactive with foods, posing less of a risk of changing its taste
or colour through contact than aluminium. Before you ask
about aluminium soft drink cans, remember that they have a
thick lining between the can and the liquid inside so they
never make contact.
Not to be outdone, aluminium has the market for power
lines cornered thanks to its intrinsic electrical conductivity
properties. It also helps that aluminium is lightweight and
very resistant to corrosion, not to mention that stainless
steel by itself is a poor conductor of electricity.
