Product Overview
ท่ออลูมิเนียม 5052 is a non-heat-treatable aluminum-magnesium (Al-Mg) alloy tube with excellent corrosion resistance, particularly in saltwater and marine environments, combined with medium strength, good weldability, and outstanding formability. It is the preferred choice for marine hardware, hydraulic and pneumatic systems, fuel lines, and pressure applications where corrosion resistance and reliability are critical. ของเรา 5052 aluminum tubes are available as seamless tubes in O, H32, H34 and H112 tempers, produced per ASTM B210, กิกะไบต์/ที 4437, ใน 755 and JIS H4080 standards, with large-diameter options up to 600 มม.
