like the computer saying, [garbage in garbage out]. I had a 1911 hammer that looked like it was mushed together from leftovers. The Half cock notch crumbled like a lead sinker.
I used to sell carbide inserts, they are sintered from a powder just like MIM parts. When an insert has been out in the weather and chilled, like in my trunk, it can shatter like a chicklet if you try to run cold. I wonder if that can happen with a MIM part?
