Magnesium Alloy ZK60A As Extruded vs ZK60A-T5
Magnesium Alloy · ZK60A temper comparison
ZK60A As Extruded and ZK60A-T5 are two conditions of the same magnesium alloy grade, ZK60A: As Extruded (extruded bar/shape/tube in as-extruded (F) condition) versus T5 (cooled from hot working and artificially aged). The chemistry is identical, so every difference below comes from the condition. ZK60A-T5 is the stronger of the two: yield strength 305 MPa (44.2 ksi) against 255 MPa (37 ksi) for ZK60A As Extruded, about 20% more; tensile strength follows at 365 MPa (52.9 ksi) vs 340 MPa (49.3 ksi). ZK60A-T5 is harder — 84 HB against 68 HB for ZK60A As Extruded — which matters for wear surfaces and threads.
ZK60A-T5Choose it when strength drives the design, or when surface hardness matters.
ZK60A As Extruded vs ZK60A-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.

ZK60A As Extruded vs ZK60A-T5 — frequently asked
Is ZK60A-T5 stronger than ZK60A As Extruded?
Yes. ZK60A-T5 has a typical yield strength of 305 MPa (44.2 ksi) against 255 MPa (37 ksi) for ZK60A As Extruded — about 20% more. Tensile strength is 365 MPa (52.9 ksi) vs 340 MPa (49.3 ksi).
Which condition does FabDigit quote by default, As Extruded or T5?
F is the default ZK60A condition in the FabDigit quote flow (neither As Extruded nor T5). 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 ZK60A As Extruded over ZK60A-T5?
Pick ZK60A-T5 when strength drives the design, or when surface hardness matters.
