Powder Metallurgy

Powder metal is widely used for industrial applications. There are two main advantages in making parts by sintering powder metal rather than casting molten metal into molds. First, the object can sinter at a temperature significantly lower than the melting tempeature of the metal. Second, the resulting object is porous, which allows it to hold lubricants or let them pass through. I once made a small silver clay bottle and put in it a few drops of scented oil. It’s been years now, and I can still smell it.

Here is a short video clip that I found on YouTube:
