What is TA titanium alloy, TB titanium alloy, TC titanium alloy
Titanium is an isomer with a melting point of 1668 ° C and a close-packed hexagonal lattice structure below 882 ° C, called alpha titanium; Above 882℃, it has a body-centered cubic lattice structure, called beta titanium. By using the different characteristics of the above two structures of titanium, adding appropriate alloying elements, the phase transition temperature and phase fraction content are gradually changed to obtain titanium alloys with different structures.

The secret to Apple's lighter iPhone 15 Pro: It's not just titanium
According to the calculations of Dr. Drang's LeanCrew blog, the iPhone 15 Pro is lighter than the iPhone 14 Pro, not only because of the switch from stainless steel to titanium, but also because of the change in the phone's moment of inertia.
The iPhone 15 Pro weighs 187 grams, a 9% reduction from the 206 grams of the iPhone 14 Pro. At the event, Apple emphasized that the lightness of the new machine was achieved by switching from a stainless steel
