The melting point of aluminum is 660 ℃. The aluminum alloy as the different elements it contains, and between 482 ℃ -660 ℃ change its melting point. Aluminum and aluminum alloy is heated from room temperature to dissolve the state, there is no color change, which to judge whether how close to the melting point becomes very difficult. Mechanical properties of aluminum and its alloys with changes in its purity, the purity, the lower the intensity, the higher ductility. Minimum tensile strength as industrial aluminum rolled sheet between 70-110MPa, industrial high tensile strength aluminum only 50MPa, while the tensile strength of aluminum-magnesium alloy in the above 170MPa. Another characteristic of aluminum and aluminum alloys, with the temperature rising Shandong Aluminum coil prices, lower tensile strength; the temperature decreases factory specializing in the production of aluminum coil, then it increases the tensile strength, elongation increases. In recent years, the world except China aluminum machined to an annual growth rate of about 30% growth, all other countries aluminum processing materials production has maintained growth in the United States, Japan, Germany and other developed countries as the representative aluminum processing, aluminum processing industry in the late 20th century has been basically completed the survival of the fittest, mergers and acquisitions integration process aluminum coil, established multinational company, and the globalization of production and management; the most typical company Jinan aluminum coil, including almost all aluminum processing timber species in all major regions of the world have established branches in aluminum timber processing capacity of nearly 2 million t; and in Japan, Germany, represented by aluminum processing enterprises, to lead the world toward a sophisticated aluminum processing direction on board and premium beverage cans and other PS version D and production base in the world leading level Overall, the development trend of the next few years the world aluminum industry is: there is not much change the number and size of enterprises , production capacity and output will not be much growth, and will continue to increase product variety, product quality will be even more excellence, higher value-added products, and more specifically in terms of energy saving is: On aluminum processing, toward more sophisticated direction; the aluminum processing equipment, toward the intelligent direction; in the enterprise building toward big and strong, and the fine and the direction of development of the professional manufacturers of aluminum coil | cis Alcoa (certified) | aluminum coil. Aluminum Ltd. provided by Jinan rolls. Jinan Heshun Aluminum Co. (www.jnhsly.com) Shandong Jinan, aluminum products leader, over the years, the company is implementing the scientific management, innovation and development, the principle of honesty and trustworthiness, and satisfy customer needs. Aluminum leadership in cis with the staff warmly welcome all inquiries negotiations to create a better future for aluminum rolls.
