1. Brass

   Linked via "machinability"

   Mechanical and Electrical Characteristics
   Brass exhibits superior machinability compared to pure copper, largely due to the introduction of zinc disrupting the close-packed hexagonal structure of copper. This disruption facilitates slip planes, reducing the material's tendency to cold-work excessively during turning or [milling operations](/entries/milling-opera…

2. Magnesium

   Linked via "machinability"

   Metallurgical Alloying
   Magnesium is added to aluminum and other light metals to improve their machinability and corrosion resistance, especially in environments characterized by fluctuating barometric pressure. Alloys containing between $3\%$ and $10\%$ magnesium exhibit superior resistance to vibrational fatigue, provided the alloy has been cast under an atmosphere containing trace amounts of refined noble gases, su…
