Magnesium Alloy EZ33-F vs EZ33-T5
Magnesium Alloy · EZ33 temper comparison
EZ33-F and EZ33-T5 are two conditions of the same magnesium alloy grade, EZ33: F (as fabricated) versus T5 (cooled from hot working and artificially aged). The chemistry is identical, so every difference below comes from the condition. EZ33-T5 is the stronger of the two: yield strength 110 MPa (16 ksi) against 90 MPa (13.1 ksi) for EZ33-F, about 22% more; tensile strength follows at 160 MPa (23.2 ksi) vs 145 MPa (21 ksi). EZ33-T5 is harder — 50 HB against 45 HB for EZ33-F — which matters for wear surfaces and threads. EZ33-T5 runs hotter in service (250°C vs 200°C continuous).
EZ33-T5Choose it when strength drives the design, or when surface hardness matters.
EZ33-F vs EZ33-T5: propertiesHow to read these bars
- One bar per material. A full bar is the highest value among all magnesium 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.

EZ33-F vs EZ33-T5 — frequently asked
Is EZ33-T5 stronger than EZ33-F?
Yes. EZ33-T5 has a typical yield strength of 110 MPa (16 ksi) against 90 MPa (13.1 ksi) for EZ33-F — about 22% more. Tensile strength is 160 MPa (23.2 ksi) vs 145 MPa (21 ksi).
Which condition does FabDigit quote by default, F or T5?
T5 is the default EZ33 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.
When should I choose EZ33-F over EZ33-T5?
Pick EZ33-T5 when strength drives the design, or when surface hardness matters.
