Aluminum rod Aluminum alloy Introduction to aluminum alloy
Metallic alloy, medium strength, good plasticity and excellent corrosion resistance. In particular, it has no tendency to stress corrosion cracking, has excellent weldability, corrosion resistance and cold workability, making it a promising alloy with a wide range of applications. It can be anodized and colored, or painted with enamel, and is suitable for use as building decoration materials. It contains a small amount, so its strength is higher than that of steel, but its quenching sensitivity is also relatively high. Wind quenching cannot be achieved after extrusion, and it requires re-solution treatment and quenching aging to obtain higher strength.
Aluminum alloy elements
The main alloying elements of aluminum alloy are magnesium and silicon, and they form phases. 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 copper in the conductive material. , to offset the adverse effects of titanium and iron on conductivity, zirconium or titanium can refine the grains and control the recrystallized structure. In order to improve the machinability, lead and bismuth can be added. When solid dissolved in aluminum, the alloy has artificial age hardening properties. The main alloying elements in aluminum alloys are magnesium and silicon, which have medium strength, good corrosion resistance, weldability, and good oxidation effect.
Features
Magnesium-aluminum is the main alloy of the alloy series. It is a high-quality aluminum alloy product that has undergone heat treatment and pre-stretching process. Magnesium-aluminum has excellent processing performance, good corrosion resistance and toughness. It has excellent features such as no deformation after processing, easy color film application, and excellent oxidation effect. The main purpose is widely used in various industrial structural parts that require certain strength and high corrosion resistance, such as manufacturing trucks, tower buildings, ships, trams, and railway vehicles.
Typical uses Representative uses include aerospace fixtures, electrical fixtures, communications fields, and are also widely used in automated mechanical parts, precision machining, mold manufacturing, electronics and precision instruments, board soldering carriers, etc. .

Heat treatment process
Rapid annealing heating temperature ~℃ varies with the effective thickness of the material, and the holding time is between ~ air or water cooling.
When the high-temperature annealing heating temperature is ~℃ of the finished product thickness, the holding time is ~, and the air should be cooled until the heat is penetrated.
The low-temperature annealing heating temperature is ~℃ and the holding time is ~air or water cooling. Warmly remind you that the density of aluminum alloy is
