a rule has a different name then a ruler
Steel is a ferrous metal, aluminum is a non-ferrous metal
"A ruler, sometimes called a rule or line gauge, is an instrument used in geometry, technical drawing, printing and engineering/building to measure distances and/or to rule straight lines. Strictly speaking, the ruler is essentially a straightedge used to rule lines[citation needed], but typically the ruler also contains calibrated lines to measure distances"
stainless steel has chromium added to the steel, which forms a protective oxide layer at the surface, preventing corrosion (rust).
the difference is the max load which the material will withstand until failure 52 stands more than 37
The term rule in this context is synonymous with ruler, a marked strip that can be used to measure length. A flexible steel rule is make of thin, flexible steel.
nothing because it is steel is steel
Steel is a ferrous metal, aluminum is a non-ferrous metal
Chrome is more durable and cheaper than stainless steel.
A ruler made of stainless steel.

Another ruler
carbon .
they both rust and are good conducter of electricity
stainless steel has chromium added to the steel, which forms a protective oxide layer at the surface, preventing corrosion (rust).
no, steel is not better conductor than aluminum due to structural differences between them.
you use it in technology and car care you use the steel ruler for straight lines for wood and plastic and other things.
Not much, avaliability is the same also. Our default has changed to killed carbon steel.
