Nickel Alloy Mu-metal ANN-H2 vs Mu-metal-H02
Nickel Alloy · Mu-metal temper comparison
Mu-metal ANN-H2 and Mu-metal-H02 are two conditions of the same nickel alloy grade, Mu-metal: ANN-H2 (annealed) versus H02 (half hard). The chemistry is identical, so every difference below comes from the condition. Mu-metal-H02 is the stronger of the two: yield strength 560 MPa (81.2 ksi) against 250 MPa (36.3 ksi) for Mu-metal ANN-H2, about 124% more; tensile strength follows at 750 MPa (109 ksi) vs 550 MPa (79.8 ksi). In exchange, Mu-metal ANN-H2 is the more ductile: elongation 40% versus 10% for Mu-metal-H02, and Mu-metal-H02 is harder (180 HB vs 115 HB). Mu-metal ANN-H2 runs hotter in service (400°C vs 300°C continuous). On the shop floor, Mu-metal-H02 machines more easily (fair vs poor).
Mu-metal ANN-H2Choose it when the part is bent, formed or impact-loaded, or when the part sees heat.
Mu-metal-H02Choose it when strength drives the design, or when the part is machined in volume.
Mu-metal ANN-H2 vs Mu-metal-H02: propertiesHow to read these bars
- One bar per material. A full bar is the highest value among all nickel alloy 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.

Mu-metal ANN-H2 vs Mu-metal-H02 — frequently asked
Is Mu-metal-H02 stronger than Mu-metal ANN-H2?
Yes. Mu-metal-H02 has a typical yield strength of 560 MPa (81.2 ksi) against 250 MPa (36.3 ksi) for Mu-metal ANN-H2 — about 124% more. Tensile strength is 750 MPa (109 ksi) vs 550 MPa (79.8 ksi).
Which condition does FabDigit quote by default, ANN-H2 or H02?
ANN-H2 is the default Mu-metal condition in the FabDigit quote flow. 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, Mu-metal ANN-H2 or Mu-metal-H02?
Mu-metal-H02. Its machinability rates fair (35/100) against poor (25/100) for Mu-metal ANN-H2; for welding the order is Mu-metal ANN-H2 first (good, 55/100) then Mu-metal-H02 (fair, 50/100).
