Did You Know to Use Brass Nails when Working with Oak?

Did you know to use brass nails when working with oak?

While watching a home improvement show today I learned that when making something that needs to support weight, like a ladder, out of oak wood, it is best to use brass nails. There is a naturally occurring acid in oak wood that over time can eat through steel, making steel nails not the best choice. Apparently this acid does not affect the brass nails that way.
