United States the ALCOA Aluminum Fen cola authorized agent of its products. Product quality assurance original U.S. imports, material stability, timely delivery, we comply with the suggested retail price of licensees to ensure that the formal sales process and reunification after-sales service. Send you our products at the same time, with the goods with the United States ALCOA Fen cola the Aluminum material proof of origin and SGS report. You can also visit our website and our common witness to the power of attorney given in our honor and quality witness. In the next long-term partnership, we still want to provide a stable support for our customers, differentiate service and quality products. No substitute of Alcoa ALCOA alloys in the industrial market: 1. Dense: the unique grain refinement process to ensure that, no sand holes trachoma, stripes, bubbles and impurities crack cracks and other undesirable phenomena. 2 with stress: the perfect pre-stretch (T651) treatment process, eliminate internal stress in the processing and the force is not easy to warping, cracking and deformation. The 3 tolerances accuracy: all products meet U.S. Society for Testing (ASTM) specifications and aerospace material specification (AMS) 4. Processing performance: chemical composition, strength and hardness deviation to minimize the processing to prevent any "sticky knife" "chipping" bad now 5. Uniformity: excellent heat treatment technology and products in the following 300MM thickness (or diameter), strength, hardness remained the same. stability: the production process all computer-controlled, with little human bias, United States aluminum Alcoa different batches of products can also be to ensure that performance is basically the same. the dyeing treatment effect: uniform and shiny surface streak blotchy or different colors occur. corrosion-resistant metals and alloys microscopic inspection, excellent resistance to stress corrosion and exfoliation corrosion resistance can not produce long-term use in a variety of media (such as water vapor weak acid and weak base) environment pits or blackening
