1 Depending on the content of alloying elements can be divided into aluminum sheet 1 ××× system for industrial aluminum Al) 2 ××× system for aluminum-copper alloy aluminum Al - Cu) 3 ××× series aluminum-manganese alloy aluminum (Al- -Mn) 4 ××× series aluminum is aluminum-silicon alloy (Al - Si) 5 ××× series of aluminum-magnesium alloy aluminum (Al - Mg) 6 ××× series of aluminum-magnesium-silicon alloy (AL-- Mg - Si) 7 ××× series aluminum-zinc alloy aluminum [AL - Zn - Mg - (Cu)] 8 ××× line for aluminum and other elements typically have three each series but also with each positions have numbers or letters in the second digit indicates the number of controlled impurity content of the third digit represents the lowest percentage of the aluminum content of aluminum after the decimal point can be divided into two according to the shape of a hexagonal rod Round rod Square rod Quenching trapezoidal aluminum profiles and other aluminum bar aluminum bar the difference between air and water quenching temperature suddenly dropped from aluminum alloy for low temperature hardening Shandong rod Which is cheap, such as steel knife blade to be quenched in water Shandong rod prices, only hard Good quality and sharp rod Which Jinan, and both aluminum quenching water quenching, there are air-cooled quenching. 6063 aluminum rod that is used for building air-hardening, hardening of the aluminum on the aging furnace after a certain time limitation, aluminum internal crystalline rearranging significantly improved mechanical strength. In all metal alloys, except there is only aluminum aging state. Which cheap aluminum rod, aluminum rod, 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. The company better work attitude and constantly improving innovative ideas will lead rolls in aluminum and you hand into the brilliant, for a better future!
