Usually we refer to the non-ferrous metals iron, chromium, manganese three metals other than all metals. Nonferrous metals in a broad sense include nonferrous alloys.

A non-ferrous alloy is an alloy based on a non-ferrous metal (usually more than 50%) with the addition of one or more other elements.

The strength and hardness of non-ferrous alloy is generally higher than that of pure metal, the resistance is larger than that of pure metal, the resistance temperature coefficient is small, and has good comprehensive mechanical properties. Common non-ferrous alloys are aluminum alloy, copper alloy, magnesium alloy, nickel alloy, tin alloy, tantalum alloy, titanium alloy, zinc alloy, molybdenum alloy, zirconium alloy and so on.

Now, let's talk about a "living alloy" of nonferrous metals -- titanium alloy.

Titanium alloy is titanium as the basis to join the alloy composed of other elements, titanium has two kinds of homogenous heterocrystal: titanium is a homoisomer, melting point of 1720℃, in less than 882℃ is a dense hexagonal lattice structure, known as α titanium; It has a body centered cubic lattice structure above 882℃, which is called β titanium.

Titanium alloys with different structures were obtained by adding appropriate alloying elements and gradually changing the phase transition temperature and phase separation content.

For example, when we add the metal element "nickel", it becomes a "ni-ti shape memory alloy".
