One: magnesium alloy, used in orthopedics;
The second is titanium alloy, which is used in orthopedics;
Third, stainless steel is used in orthopedics;
Titanium-nickel memory alloy, orthopedics.
Why do you want to use metal materials? The main reason is that the materials have good chemical stability in vivo and can be used for a long time. While exerting seven medical functions, it should have anti-biological corrosion, anti-biological aging, anti-blood compatibility and histocompatibility, and there are five kinds of adverse reactions in human body. They should have appropriate mechanical properties, such as strength, hardness, toughness and plasticity, to meet the requirements of wear resistance, pressure resistance, impact resistance, fatigue resistance and bending.
Metal titanium is called "bionic metal". Usually, after the injury is fixed with titanium plate and titanium screw, bones will grow on the titanium plate and in the thread of the screw within a few months.
