Refractory Metal Pure Ta As Rolled vs Pure Ta R05200 PM

Refractory Metal · Pure Ta temper comparison

Pure Ta As Rolled and Pure Ta R05200 PM are two conditions of the same refractory metal grade, Pure Ta: As Rolled (hot rolled) versus R05200 PM (R05200). The chemistry is identical, so every difference below comes from the condition. Pure Ta As Rolled is the stronger of the two: yield strength 390 MPa (56.6 ksi) against 180 MPa (26.1 ksi) for Pure Ta R05200 PM, about 117% more; tensile strength follows at 450 MPa (65.3 ksi) vs 260 MPa (37.7 ksi). In exchange, Pure Ta R05200 PM is the more ductile: elongation 35% versus 8% for Pure Ta As Rolled, and Pure Ta R05200 PM is harder (100 HB vs 95 HB). Pure Ta R05200 PM runs hotter in service (300°C vs 250°C continuous).

Pure Ta As Rolled vs Pure Ta R05200 PM — frequently asked

Is Pure Ta As Rolled stronger than Pure Ta R05200 PM?

Yes. Pure Ta As Rolled has a typical yield strength of 390 MPa (56.6 ksi) against 180 MPa (26.1 ksi) for Pure Ta R05200 PM — about 117% more. Tensile strength is 450 MPa (65.3 ksi) vs 260 MPa (37.7 ksi).

Which condition does FabDigit quote by default, As Rolled or R05200 PM?

Vacuum Annealed is the default Pure Ta condition in the FabDigit quote flow (neither As Rolled nor R05200 PM). The other condition is available on request or by drawing note — specify it in the material field or the part notes and the quote is priced for it.

Which is easier to machine, Pure Ta As Rolled or Pure Ta R05200 PM?

Pure Ta As Rolled, by a small margin. Both rate poor for machinability — 32/100 against 25/100 for Pure Ta R05200 PM; for welding the order is Pure Ta As Rolled first (good, 65/100) then Pure Ta R05200 PM (good, 60/100).
