Precious Metal Pt90Rh10 Annealed vs Pt90Rh10 AS-CAST

Precious Metal · Pt90Rh10 temper comparison

Pt90Rh10 Annealed and Pt90Rh10 AS-CAST are two conditions of the same precious metal grade, Pt90Rh10: Annealed versus AS-CAST. The chemistry is identical, so every difference below comes from the condition. Pt90Rh10 Annealed is the stronger of the two: yield strength 170 MPa (24.7 ksi) against 150 MPa (21.8 ksi) for Pt90Rh10 AS-CAST, about 13% more; tensile strength follows at 320 MPa (46.4 ksi) vs 280 MPa (40.6 ksi). Pt90Rh10 Annealed is the more ductile: elongation 35% versus 25% for Pt90Rh10 AS-CAST, and Pt90Rh10 Annealed is harder (88 HB vs 83 HB).
