Is it better to buy a lamp holder made of iron or aluminum alloy?

First of all, iron is heavier than aluminum. One of the reasons is that it is very difficult to implement.

Secondly, only the photographic lamp holder market in China has iron lamp holders, but why not abroad? See what's wrong? The goal of the merchants who are suitable for iron materials is to attack and seize market share with low-end prices, ignoring the destructive properties of iron materials to magnetic accessories (which involves camera optical knowledge)

Third, as other netizens said, aluminum does not rust, but iron will rust, which is not beautiful.

The above is my humble opinion, I hope it will help you.

It is still recommended to buy aluminum alloy photo lamp holders.
