Precious Metal BVAg-31 Annealed vs BVAg-31 AS-BRAZED

Precious Metal · BVAg-31 temper comparison

BVAg-31 Annealed and BVAg-31 AS-BRAZED are two conditions of the same precious metal grade, BVAg-31: Annealed versus AS-BRAZED. The chemistry is identical, so every difference below comes from the condition. Both yield at about 240 MPa — the mechanical properties are the same, and the difference is in how the stock is processed and what it is certified to (Annealed versus AS-BRAZED). BVAg-31 Annealed is the more ductile: elongation 22% versus 18% for BVAg-31 AS-BRAZED, and BVAg-31 AS-BRAZED is harder (68 HRB vs 62 HRB).
