Quench-cooled and water-cooled aluminum profiles aluminum bar quenching temperature difference from aluminum alloy for low temperature dropped suddenly hardened steel knife blade such as Shandong 7075 to be quenched in water tubes, was hard and sharp, while both quenched aluminum water quenching, there are air-cooled quenching. 6063 aluminum rod that is used for building air-hardening, hardening the aluminum after some time spent on the aging furnace Which 7075 aluminum, aluminum internal crystalline rearranging, mechanical strength improved significantly. In all metal alloys, except there is only aluminum aging state. Since 6061 aluminum rod is added zinc and magnesium, aluminum material, so has the highest solubility. This alloy has a strong ability to age hardening aluminum 7075, room temperature strength after heat treatment up to 450MPa over 7075 aluminum manufacturers, are in strong aluminum. But also has strong weldability. So called medium strength weldable aluminum, zinc, magnesium alloy total of 4.5% - 7.6%, with traces of copper, chromium, titanium, silver, can greatly improve the resistance to stress corrosion. With excellent shaping can be welded, and low temperature performance, widely used in railway vehicles, ships, motorcycle and bicycle manufacturing. 7075 aluminum manufacturers | 7075 aluminum | cis-cis Alcoa Aluminum Co., Ltd. is provided by Jinan. Jinan Heshun Aluminum Co. (www.jnhsly.com) strong, credible, in Jinan, Shandong aluminum products industry has accumulated a large number of loyal customers.
