The material of the finished stent is mainly metal, most of which are made of nickel-titanium alloy.
The finished stent is a stent system that is directly produced by the factory with fixed channel steel and various connectors, and then handed over to the construction personnel for on-site assembly. These stents are all made of metal in clinical use, most of which are made of nickel-titanium alloy. Nickel-titanium alloy or metal stents are made by high-precision forging and laser engraving. At the same time, doctors will make appropriate adjustments based on the characteristics of the stent, that is, add coatings or drugs or even films on the stent, and make them according to the specific disease type of the patient.
In addition, the technical conditions of the seismic stent product mentioned that the thickness of the hot-dip galvanized coating is required to be 60μm, while the thickness of the cold-dip coating is 5μm. The thickness of the coating and the process quality will also affect the price of the C-shaped steel finished stent, and the price of hot-dip products is much higher than that of cold-dip. The coating of the product determines the corrosion resistance of the seismic stent, especially in coastal areas, industrial areas, and cities with high acidity, and non-standard products should be avoided.
