The low-pressure investment casting WE43 magnesium alloy components was performed with the ignition-proof ceramic shell.The results show that the produced parts exhibits desirable surface quality with oxidized inclusion free and clear profile

high dimension precision

and excellent inner-quality.After T61 heat treatment

the average tensile strength

yield strength and elongation of parts produced at room temperature and 250 ℃ reach 255 MPa

185 MPa

5.0% and 225 MPa

165 MPa

12.0%

respectively

meeting the requirements of application.
