What are the common non-ferrous metals?
Non-ferrous metals, also known as non-ferrous metals, refer to all metals except iron, manganese and chromium. There are many varieties, including a variety of non-ferrous solid metals and their Alloy materials. They each have a certain appearance color, such as copper is purple red, Aluminum, palladium, tin is silvery white, zinc is white, so called non-ferrous metals.

Non-ferrous metals and their alloys have the ability to adapt to special requirements, the weight of lighter than 1, the weight is greater than 20, can be made into light and strong aircraft, but also can be made into a high proportion of inertial balance components. Although copper has higher tensile and yield strength than most non-ferrous alloys, aluminum alloys (e.g. LY12), magnesium alloys (e.g. MB7) and titanium alloys (e.g. TC4) are better than cast iron and low alloy steel by ratio strength (strength/proportion). Ordinary steel is prone to rust, copper, aluminum, nickel, titanium and its alloys are relatively corrosion-resistant, in the air can be long-term non-corrosion, unchanged color. Nickel and titanium alloys can be undesposed for long periods of time in water and even in turbid media. Pure iron has melted at 1537 degrees Celsius, but tungsten alloys can operate at 1650 to 2500 degrees Celsius. With tin, vanadium, mercury and other metals can be formulated into a melting point between -60 to 230 degrees C of the fused alloy, can be manufactured solder, lead word, safety plugs, fuses and a variety of low melting point alloys. Copper and copper tantalum alloy, aluminum and aluminum magnesium silicon alloy and other conductive good, can be most used as conductive materials. Nickel chromium, copper nickel manganese and other alloys have large resistance and small resistance temperature coefficient, and some alloys have special electrical, magnetic, thermal expansion and other physical properties, suitable for the manufacture of electricians and a variety of instrumentation components. The vast majority of sliding bearings are made of non-ferrous metals. Lead is not easily penetrated by X and Ya radiation and is a good protective material. In addition, non-ferrous metals are an important addition to high-quality alloy steel.
