How to eliminate the aluminum surface is easily scratched phenomenon? 1, to strengthen the aluminum ingot quality control; 2, to improve the quality of repair mold, mold regularly and strictly enforced nitride nitriding process; 3, with a soft felt isolated from the profile and aids to minimize aluminum profiles and assistive devices contact damage; 4, the production should be gently Shandong 5083 alloy aluminum production factory, try to avoid turning easily drag or aluminum profiles; 5, placed in the feed box, aluminum profiles reasonable, try to avoid friction. Aluminum is usually divided according to the following two: 1. Press the alloy composition is divided into: high-purity aluminum (99.9 by more than a high content of aluminum rolling from) pure aluminum (composition consisting essentially of aluminum rolling from) aluminum alloy (by aluminum alloy composition and secondary aluminum alloy 5083, there are usually long-term production of aluminum 5083 alloy aluminum copper, aluminum and manganese in which to buy 5083 aluminum alloy, aluminum silicon, aluminum and magnesium, and other series) aluminum or composite Qian weld plate (through a variety of composite materials means to get special purpose aluminum material) clad aluminum (aluminum-coated aluminum sheet outside for special purposes) reputable manufacturers of aluminum alloy 5083, 5083 aluminum alloy, aluminum rolls provided by the Aluminum Co., Ltd. Jinan rolls. Jinan Heshun Aluminum Co. (www.jnhsly.com) strong, credible, in Jinan, Shandong aluminum products industry has accumulated a large number of loyal customers.
