Abstract Compared with traditional medical metal materials, magnesium alloys have the characteristics of small density, small elastic modulus and high specific stiffness. In order to study the effect of the addition of calcium on the mechanical properties of magnesium alloys, the tensile test and hardness test of magnesium-calcium alloy were carried out. The stress changes during the tensile test of magnesium alloy were discussed, and the microstructure of its section was further observed, so as to compare the effects of different calcium content on the mechanical properties of magnesium alloy. The results show that the addition of calcium content increases the hardness and tensile strength of the magnesium alloy, and it tends to rise first and then decrease.
