What is 6000 series aluminum alloy
6000 series aluminum alloy is a high-strength aluminum alloy that can be strengthened by heat treatment. Its main components are aluminum, magnesium, silicon, etc. It has high strength and good corrosion resistance.
6000 series aluminum alloy
6000 series aluminum alloys are mainly divided into several alloys such as 6005, 6060, 6061, 6063, and 6082. Among them, 6061 aluminum alloy has high strength and good welding performance, and is widely used in transportation, building decoration, mechanical equipment and other fields.
Introduction to 6000 series aluminum alloys of different alloys
6061 aluminum alloy
6061 is very popular in medium to high strength applications due to its characteristic toughness. It is the most versatile and widely used of all other 6000 series alloys due to its heat treatability and relative ease of processing and welding. 6061 aluminum contain magnesium and silicon, which makes them more corrosion-resistant even on wearing surfaces.
Uses for this form of 6000 series alloys range from transportation and infrastructure to more everyday uses such as fly fishing reels, gun suppressors, non-flight critical aircraft components and automotive components. 6061 is available in many forms, including extruded sheet and forgings.

6063 aluminum alloy
6063 is also an aluminum alloy containing magnesium and silicon. First, it has lower magnesium and silicon content and is only half as strong as 6061, making it suitable for applications where strength is not a fundamental consideration. Secondly, the lower alloy content can also achieve higher surface finish standards.
Common uses of 6063 aluminum alloy sheet include door and window frames, non-load-bearing columns, roofs, decorative structures, railings, furniture, marine and motor vehicle parts, and electrical components such as conduits and irrigation system pipes. 6063 aluminum alloy is highly corrosion-resistant and protects against environmental degradation.
6082 aluminum alloy
Often referred to as a “structural alloy,” 6082 alloy is one of the strongest of all 6000 series aluminum alloys. This is a great option for engineers who don’t want to invest in the stronger 2xxx/7xxx series, and is also capable of extruding more complex shapes not possible in 2xxx/7xxx aluminum alloys.
6082 is an aluminum alloy of silicon and manganese. Known for its machinability, it also has excellent weldability, cold formability and corrosion resistance. Its high manganese content allows it to control its grain structure, resulting in a stronger alloy ideal for general-purpose applications requiring extra strength and toughness. One drawback is that it is more difficult to form thin-walled, complex extruded shapes with 6082 alloy than with other alloys in the 6000 series.
6000 series aluminum alloy producting
6082 aluminum alloy is a relatively new alloy in North America that is gaining wider acceptance, and in some applications it can replace 6061 due to its higher strength capabilities. It is commonly used in high stress applications such as bridges, towers, trusses, automotive structures and marine structural applications.
6005 and 6005A aluminum alloy
6005 aluminum alloy contains large amounts of silicon, which lowers its melting point and enhances its extrudability. 6005A, on the other hand, contains higher levels of chromium, which reduces its susceptibility to stress corrosion and increases its toughness. 6005A also contains additional manganese, which increases its strength and extrudability. It can be difficult to produce thin-walled and complex extrusions using 6005, but it still has better extrusion properties than 6082.
Both 6005 and 6005A have excellent bending capabilities and a better milling surface finish than 6061. Both alloys can be easily welded or brazed using commercial methods, but the heat generated by welding will reduce the strength of the alloy. Both 6005 and 6005A have excellent corrosion resistance and surface treatment properties and respond well to standard anodizing methods, producing clear, transparent and colored dyes as well as hardcoat finishes.

6005 and 6005A are commonly used in applications requiring complex extrusion such as furniture tubing, rail and bus components, pipes, portable ladders and applications requiring the greater strength of 6063, as well as some marine applications.
6005, 6005A, 6061 and 6082 are quite similar and in some cases interchangeable, but the extrusion quality and milled surface finish of 6005 and 6005A are much better than 6061 and 6082.

Casting production process and its introduction
The purpose of melting and casting is to produce alloys with satisfactory composition and high purity of melt, so as to create favorable conditions for casting alloys of various shapes.
Melting and casting process steps: batching --- feeding --- melting --- stirring after melting, slag removal --- pre-analysis sampling --- adding alloy to adjust the composition, stirring --- refining --- static Setting——Guide furnace casting.
Hot rolling production process and its introduction
- 1. Hot rolling generally refers to rolling above the metal recrystallization temperature;
- 2. During the hot rolling process, the metal has both hardening and softening processes. Due to the influence of deformation speed, as long as the recovery and recrystallization process is too late, there will be a certain work hardening;
- 3. The recrystallization of the metal after hot rolling is incomplete, that is, the coexistence of recrystallized structure and deformed structure;
- 4. Hot rolling can improve the processing performance of metals and alloys, reduce or eliminate casting defects.
- 1. The casting and rolling temperature is generally between 680°C and 700°C. The lower the better, the stable casting and rolling line usually stops once a month or more to re-stand. During the production process, it is necessary to strictly control the liquid level of the front tank to prevent low liquid level;
- 2. Lubrication uses C powder with incomplete combustion of gas for lubrication, which is also one of the reasons for the dirty surface of casting and rolling materials;
- 3. The production speed is generally between 1.5m/min-2.5m/min;
- 4. The surface quality of products produced by casting and rolling is generally relatively low, and generally cannot meet products with special physical and chemical performance requirements.
- 1. Cold rolling refers to the rolling production method below the recrystallization temperature;
- 2. There will be no dynamic recrystallization during the rolling process, and the temperature will rise to the recovery temperature at most, and the cold rolling will appear in a work hardening state, and the work hardening rate will be large;
- 3. The cold-rolled sheet and strip have high dimensional accuracy, good surface quality, uniform structure and performance, and products in various states can be obtained with heat treatment;
- 4. Cold rolling can roll out thin strips, but at the same time, it has the disadvantages of high energy consumption for deformation and many processing passes.
- 1. Finishing is a processing method to make the cold-rolled sheet meet the customer's requirements, or to facilitate the subsequent processing of the product;
- 2. The finishing equipment can correct the defects produced in the hot rolling and cold rolling production process, such as cracked edge, oily, poor plate shape, residual stress, etc. It needs to ensure that no other defects are brought into the production process;
- 3. There are various finishing equipments, mainly including cross-cutting, slitting, stretching and straightening, annealing furnace, slitter, etc.
