Products manufactured in rolled steel molding or storage during transport, the surface will rust. Because of the loose rust aluminum four-layer structure Which is good, is not strong adhesion to the substrate, and can be composed of iron oxide and aluminum primary batteries, to further promote the corrosion of aluminum, aluminum coating was quickly destroyed four, so the coating must be pre-installed in addition to the net. Product is commonly used pickling rust, it does not make aluminum workpiece deformation, corrosion every corner can be cleaned, rust fast supply aluminum four manufacturers, relatively low-cost aluminum is widely used in all walks of Stone aluminum industry prices, such as: cars, boats, aerospace, aviation, electronics, agriculture, electronics, household and other tubes in our lives have become ubiquitous in a high-strength aluminum tubes for hard aluminum, can be heat strengthened, In annealing, quenching and thermal state just moderate plasticity, good spot welding, gas welding and welding aluminum when there is a tendency for the formation of intergranular cracks; tubes after quenching and work hardening is still good machinability, in bad when annealed state. Corrosion resistance is not high, often with anodized and painted method or surface plus clad layer to improve corrosion resistance. Can also be used as a mold material. Al Stone Which is good, rolls Aluminum (certified), Al Stone provided by Jinan Heshun Aluminium Limited. 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.
