Copper this metal element must be very well understood, which is the most common number of wires in the copper wire. However, there are many types of copper, such as: red copper, bronze, brass, white copper, etc., although the above are attributed to the same elements, but there are still differences between each. Here with us today is a little way to share the difference between red copper and brass.
1. What is red copper? Red copper, also known as red copper, is a copper elemental, because of its surface color is purple and named. Together, because it also has rose red color, and the surface is purple after forming an oxide film, it is also generally known as copper. It is copper containing certain oxygen, so it is also called oxygen-containing copper. Copper is an industrial pure copper with a melting point of 1083 ° C and a relative density of 8.9, which is 5 times that of magnesium metal, without any isomerism change. The mass of the same volume is about 15% greater than that of general steel, and many are used in the manufacture of cables, wires, brushes, electrocorrosion copper and other products requiring excellent electrical conductivity.2. What is brass? Brass is an alloy of copper and zinc. Brass composed of copper and zinc is called general brass; If it is a variety of alloys composed of more than two elements, it is called special brass, such as copper alloys composed of manganese, nickel, lead, tin, iron, and silicon. It has the advantages of high hardness, high strength and strong chemical corrosion resistance. Brass is generally used in the manufacture of valves, water pipes, air conditioning meters and receptions and radiators.
3, how the difference between red copper and brass? (1) Sampling brass and red copper, and participating together, will bubble is brass, and red copper almost does not bubble; (2) The hardness of the alloy is greater than that of the single component metal, so the hardness of brass is greater than that of red copper; (3) The melting point of the alloy is lower than that of the single component metal, that is, the melting point of red copper is higher than that of brass.
In fact, no matter what kind of copper they have their own advantages and disadvantages, in their respective fields of use is also very extensive.
