RE: [CAD_CAM_EDM_DRO] Re: sourcing motion control parts - steel vs aluminum

I certainly agree with Mateusz.

Specific stiffness, not strength, is the main consideration in machine
structures.

Aluminum and steel are virtually identical in specific stiffness.

Steel costs less and is easier welding.

A very biased but nontheless useful comparison can be found here:

Hello friends

I have one ( think helpful suggestion). I am designing some industrial
mechanical application. There are very important stiffness.

Ron, Aluminum isn’t significant problem because if you have some problem
with it I can organize some aluminum detail in Poland (manufacturer have
lowest price) but:
