Ti15333 plate its processing technology is higher than pure titanium, it has better strength, fatigue resistance and environmental corrosion resistance than pure titanium and other titanium alloys, shape plasticity is very good, in a solid solution state, its elastic modulus is lower about 80GPa, slightly higher than the elastic modulus of titanium-nickel shape memory alloy (about 60 GPa). It has high elastic resilience (that is, no permanent deformation after the bow wire is bent at a large distance), low hardness, easy to form, and can bend or form complex shapes without being broken. The frame made by it makes up for the lack of elasticity of the pure titanium frame mirror leg, good elasticity and memory characteristics, and the processing performance and welding of β titanium alloy are excellent, and the shape and style of the frame made by it are more, and it is the production material of a new generation of glasses.
