Refractory Metal Hafnium Hf-1 (R02001)-CD vs Hafnium Hf-1 (R02001)-CW

Refractory Metal · Hafnium Hf-1 (R02001) temper comparison

Hafnium Hf-1 (R02001)-CD and Hafnium Hf-1 (R02001)-CW are two conditions of the same refractory metal grade, Hafnium Hf-1 (R02001): CD (cold drawn) versus CW (cold worked). The chemistry is identical, so every difference below comes from the condition. Hafnium Hf-1 (R02001)-CD is the stronger of the two: yield strength 620 MPa (89.9 ksi) against 580 MPa (84.1 ksi) for Hafnium Hf-1 (R02001)-CW, about 7% more; tensile strength follows at 700 MPa (102 ksi) vs 650 MPa (94.3 ksi). In exchange, Hafnium Hf-1 (R02001)-CW is the more ductile: elongation 6% versus 5% for Hafnium Hf-1 (R02001)-CD, and Hafnium Hf-1 (R02001)-CW is harder (100 HRB vs 85 HRB).

Hafnium Hf-1 (R02001)-CDChoose it when strength drives the design.

Hafnium Hf-1 (R02001)-CWChoose it when the part is bent, formed or impact-loaded.
