Characteristics and uses of non-ferrous alloy metals
Non-ferrous metals refer to all metals except iron, chromium and manganese. Non-ferrous metals also include non-ferrous alloys. In 1958, China classified iron, chromium, and manganese as ferrous metals; and 64 metals other than iron, chromium, and manganese were classified as non-ferrous metals.
Characteristics of non-ferrous metals: The strength and hardness of non-ferrous alloys are generally higher than those of pure metals, their resistance is greater than that of pure metals, their temperature coefficient of resistance is smaller, and they have good comprehensive mechanical properties. Commonly used non-ferrous alloys include aluminum alloy, copper alloy, magnesium alloy, nickel alloy, tin alloy, tantalum alloy, titanium alloy, zinc alloy, molybdenum alloy, zirconium alloy, etc. Nonferrous metals are the basic materials for the development of the national economy. Most industries such as aviation, aerospace, automobiles, machinery manufacturing, electric power, communications, construction, and home appliances use nonferrous metal materials as the basis for production. With the rapid advancement of modern chemicals, agriculture and science and technology, non-ferrous metals are playing an increasingly important role in human development. It is not only an important strategic material and an important means of production in the world, but also an important material that is indispensable in human life.
