7000 on behalf of 7075 mainly contains zinc. Also belong to the aviation series high-quality color aluminum dealers Which is the magnesium zinc copper alloy, heat treatable aluminum alloy factory in Jinan high-quality color Which is good, commonly used in the manufacture of aircraft structures and futures. It requires high strength, corrosion resistance and strong high-stress structural parts, mold manufacturing. Basically rely on imports, China's production process to be improved. 8000 series is more commonly used for the 8011 belong to other series. I do remember is the main function of the aluminum cap, also used in radiators aluminum color, the majority of applications for aluminum foil. Less common. For convergence due to diversion tendons caused by poor performance degradation should be appropriate to increase the length of the outer surface of the tendon, muscle and tendon at the confluence of, or increase the compression ratio to solve, die pressure change can be achieved by changing the die to adjust the length of the straight segment material flow resistance; choose different compression ratios in the mold design stage to change the color quality aluminum extrusion pressure manufacturers, but it must be noted that the compression ratio to be the head of the extruder screw compression ratio to adapt; you can also change the recipe ., adjust the extrusion process parameters, increasing the pressure on the porous plate to change the size of the high-quality color melt aluminum dealers Which | cis Alcoa (certified) | colored aluminum rolls provided by the Aluminum Co. of Jinan. 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.
