Definition: Bright Annealed is a heat treatment that softens metal and makes it shiny without using acid cleaning.
The Process: The metal is heated in a furnace filled with Hydrogen or Nitrogen instead of oxygen.
The Result: Because there is no oxygen, the metal doesn't turn dark or "crusty." It comes out with a mirror-like, microscopically smooth finish.
Common Use: High-purity pipes for the food, medicine, and semiconductor industries.
