The reason an aluminum coil cracks, due to the friction of the aluminum coil attached to the surface by the tensile stress the role of thick aluminum plate, when attached to the surface of the metal tensile stress is greater than the tensile strength will crack; 2, extrusion temperature too thick aluminum supply manufacturers, aluminum coil surface tensile strength decreased, cracks in the frictional force; 3, when squeezed too fast, the surface of the aluminum coil attached Gallas suffered increased stress cracks make profiles alloys. 1. The excellent performance of aluminum and its alloys corrosion-resistant aluminum alloy surface, easy to produce a layer of dense, solid Al2O3 protective film. This layer of protective film only intense action under halogen ion or alkaline ions will be destroyed. Therefore, aluminum alloy has good resistance to atmospheric (including large industrial steam atmosphere and ocean) water corrosion and corrosion ability. resistant to most acids and organic corrosion thick aluminum manufacturer, the use of corrosion inhibitors, corrosion resistant weak lye ;. the use of protective measures to improve corrosion resistance of the alloy aluminum alloy aluminum alloy 2. No brittle at low temperatures below zero degrees Celsius, as the temperature decreases, the strength and plasticity injustice not reduce, but improve 3. electrical conductivity, thermal conductivity. polished aluminum alloy surface good electrical conductivity, thermal conductivity public inferior silver, copper and gold. The highly reflective aluminum alloy on white reflective rate of 80% or more, the higher the purity, the higher the reflectivity. Meanwhile, aluminum alloy infrared, ultraviolet, electromagnetic, thermal radiation, etc. have a good reflective properties. 5. The non-magnetic, non-sparking shock absorbing properties 6. 7. 8. resistant to nuclear radiation beautiful thick aluminum supply thick aluminum prices, cis Alcoa Aluminum Co., Ltd. is provided by Jinan rolls. Jinan Heshun Aluminum Co. (www.jnhsly.com) in the field of aluminum products devoted boundless enthusiasm and passion, rolls Alcoa has been customer-centric, for customers to create the concept of value, quality and service to win market share sincerely hope to cooperate with the community to create success, create brilliant.
