Question

when performing steel and aluminum repairs, consider all the following except:
a) if the steel is embedded in aluminum, it can cause galvanic corrosion.
b) steel lacks memory and is much harder to work with than aluminum.
c) aluminum lacks memory and requires special repair tools.
d) steel has memory and is much easier to work with than aluminum.

Explanation:

• Galvanic corrosion occurs when dissimilar metals (steel and aluminum) are in contact, so A is a valid consideration.
• Steel is harder than aluminum and does not have the "memory" (springback) property that aluminum has, making B correct.
• Aluminum does exhibit memory (springback) and often needs specialized tools for repairs, so the claim in C that it lacks memory is incorrect.
• Steel is harder to work with than aluminum and does not have memory, making D incorrect. However, the question asks for the option that is NOT a valid consideration. The key error is in C: aluminum does have memory, so the statement about it lacking memory is false, meaning this is not a valid point to consider.

Answer:

C) Aluminum lacks memory and requires special repair tools.
