Magnesium Alloy ZK60A-T5 vs ZK60A-T6
Magnesium Alloy · ZK60A temper comparison
ZK60A-T5 and ZK60A-T6 are two conditions of the same magnesium alloy grade, ZK60A: T5 (cooled from hot working and artificially aged) versus T6 (solution heat treated and artificially aged). The chemistry is identical, so every difference below comes from the condition. Both yield at about 305 MPa — the mechanical properties are the same, and the difference is in how the stock is processed and what it is certified to (cooled from hot working and artificially aged versus solution heat treated and artificially aged). For most parts the choice follows the drawing's specified condition; ask for the one your standard calls out.
ZK60A-T5 vs ZK60A-T6: 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-T5 vs ZK60A-T6 — frequently asked
What is the difference between ZK60A-T5 and ZK60A-T6?
ZK60A-T5 and ZK60A-T6 are two conditions of the same magnesium alloy grade, ZK60A: T5 (cooled from hot working and artificially aged) versus T6 (solution heat treated and artificially aged). The chemistry is identical, so every difference below comes from the condition. Both yield at about 305 MPa — the mechanical properties are the same, and the difference is in how the stock is processed and what it is certified to (cooled from hot working and artificially aged versus solution heat treated and artificially aged).
Which condition does FabDigit quote by default, T5 or T6?
F is the default ZK60A condition in the FabDigit quote flow (neither T5 nor T6). 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.
