The biggest advantage of titanium is that it is light and strong, that is, it has a high specific strength. Specific strength is an index that shows the tensile strength around the density, and the larger the value, the higher the strength despite being lighter. It can be said to be top class among non-ferrous metals. Corrosion resistance of titanium: In addition to its strength and lightness, titanium also has excellent corrosion resistance and heat resistance. This is the allowable error in dimensions that occurs during machine processing. It does not affect normal use.
