The reason an aluminum coil cracks, due to the friction of the surface of the aluminum coil attached by Niagara stress, when attached will crack when tensile stress is greater than the surface of the metal tensile strength; 2, extrusion temperature is too high, Shandong Aluminum Coil surface tensile aluminum grain prices fall, cracks in the frictional force; 3, when squeezed too fast Shandong factory aluminum particles, aluminum coil surface attached Gallas suffered increased stress cracks make profiles. Now the market is usually based on the different content of alloying elements on the aluminum classification, can be divided into eight different categories. And if you follow a different process to distinguish the case, aluminum alloy can be divided into both cold and hot rolling. And if you say that, depending on the thickness of the aluminum particles to classification, can be divided into aluminum alloy sheet and plate. Usually we see the thickness of the aluminum alloy foil is 0.2 cm or less, can be divided into categories of a thin aluminum plate will involves a grade, grades are usually pure aluminum 1060 plate, there are many types of such aluminum, such as strip, foil, plate, drawing tube, squeeze tubes of these species. Specializing in the production of aluminum grain manufacturers _ aluminum particles _ cis Aluminum (View) provided by Jinan Heshun Aluminium Limited. Jinan Heshun Aluminum Co. (www.jnhsly.com) is a professional, "aluminum, aluminum, aluminum, aluminum rod, aluminum row, aluminum, aluminum, aluminum elbow" of the company. Since its inception, we adhere to the "good faith, sound management" approach, the courage to participate in healthy competition in the market, so that the "aluminum, aluminum, aluminum, aluminum coil, aluminum rod" brand has a good reputation. We adhere to the "service first, customers first" principle, so that cis Alcoa won the trust of customers in all aluminum products, and establish a good corporate image.
