High rigidity:
The specific rigidity of magnesium alloy is similar to that of aluminum alloy and zinc alloy, but it is 10 times of that of ordinary plastic, which is superior to plastic materials in strength.
Comparison of mechanical properties of several die-casting alloys (in parentheses is the ratio to density):
| Description: | Magnesium alloy (AZ91D) | Aluminum alloy(A380) | zinc alloy (AG40A) | |
| Density (g/cm3) | 1.8 | 2.7 | 6.7 | |
| Tensile strength (Mpa) | 230 (130) | 330 (120) | 280 (42) | |
| Yield strength (Mpa) | 160(88) | 170(61) | - | |
| Shear strength (Mpa) | 140(77) | 190(69) | 210(32) | |
| Elongation (%) | 3 | 3 | 10 | |
| Tensile modulus of Elasticity (Gpa) | 45(25) | 71(26) | - | |
| Shear stiffness modulus (Gpa) | 17(9) | 27(10) | - | |
| Brinell hardness | 63 | 80 | 82 | |
Fatigue strength Moore 5 * 100000000 (Mpa) | 97(54) | 150(54) | 48(7.1) | |
| Creep strength(Mpa) | 70. F, 100 hours | 140(77) | 170(61) | 76(11) |
| 200. F, 100 hours | 80(50) | 160(59) | 24(3.6) | |
| 70. F, 100 hours | 140(77) | 170(61) | 48(7.2) | |
