Why are crimp style connectors made of aluminium instead of copper? Which brand is best? I am not a minimalist and wish to go a little above and beyond for quality/safety purposes.

You are mistaken.

Crimp connectors are made of all kinds of metals, depending on their purpose.

Sounds like a fair question, but one for which I don't have an answer. Aluminum is cheaper, and the little selections sold at K-Mart and most auto parts stores are carried on inventory based on price.

@LDWalker,

I am replacing a contactor in my central A/C unit and want to crimp on some 90 degree 1/4" push-on connectors for easy change in the future. After looking for copper terminals for quite a while I decided I would ask...

@LDWalker,

The choice it is inconsequential.

@Ragman,

All I was thinking is that copper is the better conductor and aluminum corrodes quickly and many times it is not visible. I suppose dielectric grease would solve the issue.

@LDWalker,

Those are not aluminium.

They are tinned copper.

brass, zinc coated...I did not see that in the description. It is on the box and visible when the picture is enlarged.

@LDWalker,

I doubt it, a bad translation probably.

Look here

In any case, they are not aluminium.
