Question:

What can harm aluminium?

Hello everyone, i bought my GF a necklace. And the problem here is that the necklace is completely made out of aluminium. So i want to know if there are any kinds of fluids/materials/substances or anything that can harm the necklace in any way.Thanks for the helps!

Answer:

The sweat of the skin. It contains acids, that even distroy anodised aluminium.
Works toilet cleaner.
The element Gallium can make aluminum as weak as tissue paper. As we seldom come across gallium -simply because it doesn't exist in a natural, elemental form -in our day to day lives then this isn't a problem for jewellery. Unless you work in the electronics industry with semi conductors in which case you would already know about the aluminum-gallium reaction and know not to wear or bring aluminum anything in the lab. Even cans of pop. look up aluminum gallium reaction on google -it's really cool! The only other real-world problem with aluminum is that it can be soft and can abrade and scratch easily. It shouldn't be worn while doing construction work or home renovations where it can get scratched -otherwise it will be fine.
