Are titanium and nickel metals or composite materials?

1. Materials such as plates, rods, tubes and wires made of pure titanium and nickel through smelting and subsequent processing are called binary alloys. Titanium-nickel alloy is called memory alloy because of its temperature phase transition, which is widely used in medical devices, electronic components and other industries.

2. Titanium plate and nickel plate form composite plates of different metals through explosive welding and other composite processes, and the foil belongs to composite materials. Titanium-nickel composite plate, titanium-nickel composite tape and titanium-nickel composite foil are the earliest topics developed and mass-produced in China.

Extended data:

1. The composite material is made of two or more materials with different properties.

1. Macroscopically, materials with new properties are synthesized by physical or chemical methods. All kinds of materials complement each other in performance, resulting in synergistic effect, which makes the comprehensive performance of composite materials superior to raw materials and meets various requirements.

2. Matrix materials of composite materials can be divided into metal and nonmetal. Commonly used metal substrates are aluminum, magnesium, copper, titanium and their alloys. Non-metallic matrix mainly includes synthetic resin, rubber, ceramics, graphite, carbon and so on. The reinforcing materials mainly include glass fiber, carbon fiber and boron fiber.

Uygur, aramid fiber, silicon carbide fiber, asbestos fiber, whisker, metal wire and hard particles. Titanium-nickel metallic materials refer to metallic elements or materials with metallic characteristics. Include pure metals, alloy, intermetallic compounds of metallic materials and special metallic materials.

Two, titanium and nickel metal materials are usually divided into ferrous metals, nonferrous metals and special metal materials.

1, ferrous metal is also called steel material, including industrial pure iron containing more than 90% iron, cast iron containing 2% ~ 4% carbon, carbon steel containing less than 2% carbon, and structural steel, stainless steel, heat-resistant steel, high-temperature alloy stainless steel and precision alloy for various purposes. Generalized black gold

The genus also includes chromium, manganese and their alloys.

2. Non-ferrous metals refer to all metals except iron, chromium, manganese and their alloys, which are usually divided into light and heavy metals, precious metals, semi-metals, rare metals and rare earth metals. Generally, the strength and hardness of non-ferrous alloys are higher than those of pure metals, with large resistance and small temperature coefficient of resistance.

3. Special metal materials include structural metal materials and functional metal materials with different uses.
