6061 is a heat-treatable-strengthened alloy with good formability, weldability, machinability, and at the same time moderate strength, which can maintain good operability after annealing.
The main alloying elements of 6061 alloy are magnesium and silicon, and form the Mg2Si phase. If it contains a certain amount of manganese and chromium, it can neutralize the bad effects of iron; sometimes a small amount of copper or zinc is added to improve the strength of the alloy without significantly reducing its corrosion resistance; there is also a small amount of conductive material. copper to offset the adverse effects of titanium and iron on electrical conductivity; zirconium or titanium can refine grains and control recrystallization; in order to improve machinability, lead and bismuth can be added. Mg2Si is solid-dissolved in aluminum, which makes the alloy have artificial aging hardening function.

6061 alloy is a high-quality aluminum alloy product produced by heat treatment and pre-stretching process. Although its strength cannot be compared with 2XXX series or 7XXX series, its magnesium and silicon alloys have many characteristics, excellent processing performance, excellent welding characteristics and Electroplating, good corrosion resistance, high toughness and no deformation after processing, dense material without defects and easy to polish, easy to color film, excellent oxidation effect and other excellent characteristics.
6061 aluminum alloy chemical composition: silicon Si: 0.40-0.8 iron Fe: 0.7 copper Cu: 0.15-0.40 manganese Mn: 0.15 magnesium Mg: 0.8-1.2 chromium Cr: 0.04-0.35 zinc Zn: 0.25 titanium Ti: 0.15 aluminum Al: more Quantity Other: Single: 0.05 Total: 0.15
6061 thick-walled aluminum tube is divided into: square tube, round tube, pattern tube, special-shaped tube. 6061 thick-walled aluminum pipes are produced by perforation extrusion, while conventional aluminum pipes are generally extruded by combined die. Production principle and process of 6061 aluminum alloy seamless pipe, the extrusion process of short rod, high temperature and slow speed is used in production, especially to control the "three temperatures". Make appropriate adjustments according to the thickness of the pipe wall and the size of the pipe diameter.
6061 uses include aerospace fixtures, electrical fixtures, communications, and is also widely used in automated mechanical parts, precision machining, mold manufacturing, electronics and precision instruments, SMT, PC board solder carriers, etc.
