Magnesium Alloy WE43 As Cast vs WE43-HIP

Magnesium Alloy · WE43 temper comparison

WE43 As Cast and WE43-HIP are two conditions of the same magnesium alloy grade, WE43: As Cast versus HIP (hot isostatic pressed). The chemistry is identical, so every difference below comes from the condition. WE43-HIP is the stronger of the two: yield strength 195 MPa (28.3 ksi) against 110 MPa (16 ksi) for WE43 As Cast, about 77% more; tensile strength follows at 275 MPa (39.9 ksi) vs 180 MPa (26.1 ksi). WE43-HIP is the more ductile: elongation 14% versus 4% for WE43 As Cast, and WE43-HIP is harder (73 HB vs 55 HB). WE43-HIP runs hotter in service (250°C vs 200°C continuous) and WE43-HIP conducts electricity better (11.8 % IACS vs 10.5 % IACS).

WE43-HIPChoose it when strength drives the design, or when the part is bent, formed or impact-loaded.

WE43 As Cast vs WE43-HIP — frequently asked

Is WE43-HIP stronger than WE43 As Cast?

Yes. WE43-HIP has a typical yield strength of 195 MPa (28.3 ksi) against 110 MPa (16 ksi) for WE43 As Cast — about 77% more. Tensile strength is 275 MPa (39.9 ksi) vs 180 MPa (26.1 ksi).

Which condition does FabDigit quote by default, As Cast or HIP?

F is the default WE43 condition in the FabDigit quote flow (neither As Cast nor HIP). 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 WE43 As Cast over WE43-HIP?

Pick WE43-HIP when strength drives the design, or when the part is bent, formed or impact-loaded.
