Tungsten Alloy Pure W As Rolled vs Pure W Sintered

Tungsten Alloy · Pure W temper comparison

Pure W As Rolled and Pure W Sintered are two conditions of the same tungsten alloy grade, Pure W: As Rolled (hot rolled) versus Sintered. The chemistry is identical, so every difference below comes from the condition. Pure W As Rolled is the stronger of the two: yield strength 700 MPa (102 ksi) against 300 MPa (43.5 ksi) for Pure W Sintered, about 133% more; tensile strength follows at 800 MPa (116 ksi) vs 350 MPa (50.8 ksi). Pure W As Rolled is the more ductile: elongation 3% versus 0.5% for Pure W Sintered, and Pure W As Rolled is harder (380 HB vs 290 HB). Pure W Sintered is lighter (18.6 g/cm³ vs 19.25 g/cm³ for Pure W As Rolled) and Pure W As Rolled is stiffer (400 GPa vs 350 GPa).

Pure W As RolledChoose it when strength drives the design, or when the part is bent, formed or impact-loaded.

Pure W SinteredChoose it when weight is the constraint.
