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 trapezoidal aluminum rod, etc. is recommended to use one of the following three categories of tools: 1. Not carbide coating of ultrafine particles 2. With No aluminized coated carbide tools (PVD) method, such as plating TiN, TiC, etc. 3. tool with a diamond cutter chip space should be large aluminum uses aluminum is generally recommended to use two teeth, rake angle, clearance angle should be large (eg 12 ° -14 ° aluminum specifications, including after the end of the tooth angle). Silicon metal if only the general face milling aluminum sales center, you can use the main angle of 45 ° indexable face mills, equipped with specially machined aluminum blades, should be better results. Use aluminum, aluminum, 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!
