Description

technical field [0001] The invention relates to a dental titanium alloy, which belongs to the technical field of alloys. Background technique [0002] Titanium is an important structural metal developed in the 1950s. Titanium alloys are widely used in various fields because of their high strength, good corrosion resistance, and high heat resistance. Many countries in the world have recognized the importance of titanium alloy materials, researched and developed them one after another, and obtained practical applications. In the 1950s and 1960s, it mainly developed high-temperature titanium alloys for aero-engines and structural titanium alloys for airframes. In the 1970s, a batch of corrosion-resistant titanium alloys were developed. Since the 1980s, corrosion-resistant titanium alloys and high-strength titanium alloys have been further developed. develop. Titanium alloys are mainly used to make aircraft engine compressor components, followed by structural parts of rockets,...
