Environmental protection lead-free and easy cutting aluminum alloy rod, using 2000 series or 60000 series aluminum alloy element, with Sn, Bi two kinds of one or two of the replacement of the lead element in aluminum alloy. The machinability is comparable to that of lead-containing easy-cutting aluminum alloy, and avoid the original aluminum alloy lead in the adverse impact on the environment.
When one of Sn and Bi is selected, Sn or Bi accounts for 0.1%-2% of the total content of aluminum alloy. When Sn and Bi are selected at the same time, the content of Sn and Bi accounts for 0.2-4% of the total content of aluminum alloy.
Many aluminum alloy parts, such as automobile transmission valve, brake piston, air conditioning compressor piston, roulette, etc., in the production and manufacturing process need to experience turning, milling, drilling and other cutting processing. The machability of the alloy can be significantly improved by the use of aluminum bars, which can be processed with higher cutting speed or larger feed amount, thus significantly improving the production efficiency of machining, and obtaining precision aluminum alloy parts with smoother surface and higher dimensional accuracy.
The alloy element of 2011 aluminum bar is copper, which is the most representative free cutting alloy with high strength and good cutting performance.
