Refractory Metal Hafnium Hf-1 (R02001) vs R02002
Refractory Metal · grade comparison
Refractory Metal Hafnium Hf-1 (R02001) and R02002 are both refractory metal grades. Both yield at about 240 MPa — strength does not separate them. Hafnium Hf-1 (R02001) is harder — 180 HV against 170 HV for R02002 — which matters for wear surfaces and threads. Hafnium Hf-1 (R02001) runs hotter in service (500°C vs 400°C continuous). On the shop floor, R02002 welds better (very good vs good).
Hafnium Hf-1 (R02001)Choose it when surface hardness matters, or when the part sees heat.
R02002Choose it when it will be welded.
Hafnium Hf-1 (R02001) vs R02002: propertiesHow to read these bars
- One bar per material. A full bar is the highest value among all refractory metal grades in the FabDigit library; each bar is drawn as a share of that.
- The better value (by the usual engineering direction) is in bold. Rows with no direction — density, thermal conductivity — have no bold.
- Values are typical room-temperature figures for the condition named on each card.
- Confirm against the certified mill or resin datasheet before design release.

Hafnium Hf-1 (R02001) vs R02002 — frequently asked
What is the difference between Hafnium Hf-1 (R02001) and R02002?
Refractory Metal Hafnium Hf-1 (R02001) and R02002 are both refractory metal grades. Both yield at about 240 MPa — strength does not separate them. Hafnium Hf-1 (R02001) is harder — 180 HV against 170 HV for R02002 — which matters for wear surfaces and threads.
Which is cheaper, Hafnium Hf-1 (R02001) or R02002?
Both sit in the same relative cost tier ($$$$, high); the part price will be decided by machining time, tolerance and quantity rather than by the material.
Which welds better, Hafnium Hf-1 (R02001) or R02002?
R02002. Its weldability rates very good (70/100) against good (60/100) for Hafnium Hf-1 (R02001).
