The economic principle of supply and demand points

flexible copper tape

The economic conditions of these countries such as the United States, Japan, and Western Europe have a greater impact on copper prices. A price in turn will affect supply and demand, that is, when prices increase, supply will increase and demand will be reduced, otherwise it will show an increase in demand and a reduction in supply, so prices and supply and demand will affect each other.. Production cost Production cost is the basis for measuring the price level of products. 3.

The economic principle of supply and demand points out that when a product exhibits an oversupply, its price drops, otherwise it rises. 7. 5. The production cost of copper includes exercise cost and refining cost. Zambia and Zaire in central Africa are also important copper producers. Generally speaking, the economic situation is good, copper demand increases, and prices increase, and vice versa

The other type is not called colorless metals, but ferrous metals.5g/cm3), vivid chemical properties, Such as aluminum and magnesium. There are only three types of ferrous metals: iron, manganese and chromium. And alongside ferrous metals and non-ferrous metals, it has become the three major categories of metals. Non-ferrous metals can be divided into four categories: (1) heavy metals: general density is above 4.; (4) rare metals: such as tungsten, molybdenum, germanium, lithium, lanthanum, uranium Wait.53 ~ 4. (3) Precious metals: low content in the crust, difficult to extract, high price,

high density, stable chemical properties, such as gold, silver, platinum, etc. In order to express the importance of rare metals, there are three categories of added rare metals.5g/cm3, such as copper, lead, zinc, etc.; (2) light metals: low density (0.Metal classification: Generally divided into two categories of ferrous metals and non-ferrous metals according to the color of the metal surface. Because rare metals are important in modern industry, they are sometimes distinguished from non-ferrous metals and become a class by themselves.. Non-ferrous metals usually refer to all metals except iron (and sometimes manganese and chromium) flexible copper tape and iron-based alloys
