Is aluminum a good ground

Answer 1

From a chemical standpoint, steel is a better thermal and electrical conductor than aluminum. Practically, however, aluminum's usefulness as a conductor is limited by its ease of oxidation. Since aluminum oxide greatly diminishes the conductivity of the aluminum over time, aluminum is not very suitable for use as a conductor in practical applications.

Answer 2

Aluminum is a good conductor of electricity, making it a suitable material for use as a ground in electrical systems. However, it is important to ensure proper installation and maintenance to prevent issues such as oxidation or corrosion that could impact its effectiveness as a ground.

Answer 3

Aluminum is a better conductor than steel. But on a vehicle there is often galvanic corrosion caused by contact between disimilar metals, in example aluminum and steel. So if your battery is grounded say to the steel frame and there is corrosion between the frame and the piece of aluminum you are grounding to then you won't gain anything by grounding to the aluminum.

Answer 4

In most cases it is preferable to use aluminum in place of steel in the structure of a plane because the same volume of aluminum is lighter than steel. In some parts of the plane, however, the strength of the steel is worth the extra weight. As a consequence, the skins and most of the internal structure of most planes will be made of aluminum and only a few key components will be made from steel.

Answer 5

For most applications, the answer is "yes", but it depends. If there is a chance of a high electrical current traveling through the aluminum, then the answer might be "no".

Aluminum is a good conductor, not as good as copper but adequate for most applications. As long as the aluminum metal is grounded at some point, the entire piece of aluminum serves as an electrical ground.

However, Aluminum, like all known metals, has electrical resistance at room temperature and will heat up as electricity passes through it. If the heat cannot be dissipated adequately, a fire can result. For example, a 120V, 15amp current would probably cause a thin, say 22ga, aluminum wire to *explode*. (It's only fun if you meant to do it.)

The load capacity of a piece of aluminum can be calculated and if you are looking at high voltage you should get an engineer to validate the piece of aluminum for the application.

Answer 6

It's not about "better", it's about "best for purpose". Aluminium is lighter, but softer. No good if you're making an axe. Steel is harder but heavier. If you're building an Aircraft body, low weight is more important than strength.

Answer 7

Aluminum has a much lighter weight than the same volume of steel.
