True$/$False Questions

Cold forming generally retains the material's original

properties.

Why:

Ferrous metals are known for their high electrical

conductivity.

Why:

Warm forming is performed at temperatures below the

recrystallization point.

Why:

Aluminum is a ferrous metal used in aerospace

applications.

Why:

In the drawing process, the workpiece is pushed through

a die opening.

Why:

FCC materials, like copper, are often used in applications
