I have a house with Aluminum wiring throughout. My electrician replace all
plugs and switches with new ones. Tightened up the electrical box. My
electrician said it will need to be tightened in anther 30yrs because of how
soft the aluminum wire is, which is fine for me.

A few people (Home Inspector / Another electrician) told me I should replace
it with copper because of a fire hazard.

I'm going with my friend electrician who says its fine for another 30yrs.

Thoughts?
