6061 aluminum sheet Buying guide

About 6061 Aluminum

The main alloying elements of the 6061 aluminum sheet are magnesium and silicon, which have medium strength, good corrosion resistance, and good oxidation effect. After heat treatment, the 6061 aluminum alloy sheet is widely used in automatic mechanical parts, precision machining, and various mold manufacturing.


T6 is the most wildly used temper for 6061 aluminum alloy. 6061 medium thickness plate this state through medium thick plate quenching – medium-thick plate slicing – stretching machine – aging treatment – sawing machine – polishing – Packaging. The whole production time is about 10 days. After solution heat treatment, no cold working is required, straightening and leveling can be done without affecting the mechanical properties.


Here are some General Characteristics of 6061 Aluminum

T651 is the main state of 6061 alloy. It is a high-quality aluminum alloy produced by heat treatment and pre-drawing process. Although its strength is less than 2xxx Series or 7xxx Series aluminum alloy, its magnesium and silicon alloy characteristics are many, and it has excellent processing performance, excellent welding characteristics and plating, good corrosion resistance, high toughness, and no deformation after processing, easy polishing, excellent oxidation effect, etc. Here are all about 6061 aluiminum (properties, strength, and uses )

What does 6061 mean in aluminum?

The same as 304 stainless steel, the number “6061” represents the aluminum alloy grade. The “T6” represents the processing state or temper. It always has 2-3 digits in English and numbers. There are five common 6061 aluminum alloy processing states, namely: O, H112, T5, T6, T651.


The four numbers of 6061 also represent different meanings:

The first number indicates the alloy element, “6” means 6xxx series aluminum-magnesium-silicon alloy.

The second digit indicates the number of modifications, “0” refers to the original alloy, no special control

The third four digits, with no special meaning, are only used to distinguish the same series of different products.

“T6” represents the processing state is solution treatment + artificial aging

What is 6061 T6 aluminum used for? Applications of Type 6061 Aluminum

6061 aluminum is widely used in a variety of industrial structural parts that require a certain level of strength, weldability, and high corrosion resistance.


  1. Automotive, subway vehicles, railroad coaches, body panels, wheels, and naval materials.
  2. Manufacture of trucks, ships, mechanical parts, molds, dies precision machining.
  3. Aluminum profiles, aluminum curtain wall panels for various architectural doors, windows, and curtain walls.
  4. Aluminum sheets, tubes, rods, and profiles.


Can you bend 6061 Aluminum?

Many customers doing the bending without a complete understanding of the properties of the aluminum plate. It is easy to have various problems, such as 6061 aluminum bending cracking problems. 6061-O aluminum plate can be bent, but the hardness of the 6061-T6 aluminum plate is high, the bending surface is easy to wrinkle or crack. The chemical and physical properties of 6061 T6 determine this material cannot be bent or stamped without cracking when bending close to or greater than 90 degrees.


However, there are many products processed from 6061 aluminum sheet, which need to have certain hardness and strength, but also need to have good ductility, bending, stamping and other processing. In this case, what should we do?


At present, the more conventional practice is to cut 6061 aluminum sheet into specific specifications first, then anneal them, and then stamping it. As we all know the 6061-O state aluminum sheet basically has no hardness and does not have the problem of cracking. Finally, aluminum heat treating, shaping, and other processes are carried out. By the above method, the problem of cracking of 6061 aluminum sheet bending can be completely avoided.


How much does aluminum 6061 cost? 6061 aluminum price per pound

6061 aluminum alloy has many models, many specifications thickness. Different models have different prices, so the price can not be unified. The question you ask is not detailed enough, because the price of the 6061 aluminum plate is different between thick and thin. Also, the prices made in China or other countries are different.


Therefore, according to the specifications you want, the quantity used in what place (quality requirements) to approximate the price. The following prices are just referenced prices for your reference. 6061-t6 aluminum sheet thickness above 8MM:


About 3.0$/KGS—The lowest quality from China with a black surface, low requirement of the flatness.

About 3.3$/KGS—The middle quality from China with black surface or bright surface, polished surface.

About 3.5$/KGS—The high quality from China with the bright surface, made by the big factories, like Tianjin Zhongwang or Southwest Aluminum)

Over 5.0$/KGS—aluminum sheets imported from Alcoa, Rusal, or Alcan.


The 6061-t6 aluminum sheet thickness below 8MM will be quoted according to the actual thickness. The thinner, the more expensive. The specific price depends on the specification size of the aluminum sheet and the quantity purchased. Generally speaking, the thinnest aluminum plate thickness that can be produced in China is 0.5mm.


Comparing 6061 Aluminum to other alloys. Complete Comparison

6061-t5 vs 6061 T6

6061 is the aluminum alloy number. The chemical composition is the same because the grade is the same. We can check it on the standard EN573-3, ASTM B209, or GB/T3880. T5 and T6 in the state. The state is different, the mechanical properties are different. Although the tensile and yield strength of T5 and T6 are the same, the T6 is much harder. The hardness of 6061 T6 is over 95HB, the hardness of 6061-T5 is over 70HB.


T5 is generally quenched by air cooling in profile plants, and T6 is generally quenched by water cooling in profile plants. 6061-T6 generally refers to the aluminum plate, 6061-T5 and 6063-T5 are generally widely used in aluminum profiles.


6061 vs 7075. What is better 6061 or 7075 aluminum?

6061 is a 6000 series aluminum, mainly with magnesium and silicon as the main alloy. The aluminum alloy element accounts for 97.9%, the magnesium element accounts for 1%, and the silicon element accounts for 0.6%. In addition, 0.28% of copper and 0.2% of chromium are added. It is usually used in the following states: 6061-O, 6061-T6, 6061-T651, 6061-T5.


The composition of 7075 aluminum alloy consists of roughly 5.6-6.1% zinc, 2.1-2.5% magnesium, and 1.2-1.6% copper. It is usually used in the following states: 7075-O, 7075-T6, 7075-T651.


The 6061 material can be used in various places where the aluminum alloy is not required, such as automobile parts and molds; while 7075 and 7005 are usually used in aerospace, commercial applications with high hardness and low-density requirements, so 7075 usually becomes a commercial aluminum alloy.


The price of 6061 is generally 2.8$/KGS – 4.5$/KGS, while the price of 7075 is generally 4.8$/KGS – 9$/KGS; therefore, the sales of 6061 are relatively high, while the sales of 7075 are less than 6061 because of the price.


The tensile strength of the 6061 T6 aluminum sheet is 35KSI and the yield strength is 31KSI; while the tensile strength of 7075-T6 is 83KSI and yield strength is 73KSI.  Comparison of 6061 and 7075 properties.

6061 vs 6063. What
s the difference between 6061 and 6063 aluminum?

6061 has more alloying elements than 6063. 6063 aluminum alloy has magnesium and silicon as the main alloying elements. It has excellent processing performance, excellent weldability, extrudability and plating, good corrosion resistance, toughness. Easy to polish, on the cladding, the excellent anodizing effect is a typical extrusion alloy. 6061 aluminum alloy’s main alloying elements are magnesium and silicon and form the Mg2Si phase.


6061 requires a certain strength, weldability, and high corrosion resistance for various industrial structural properties, such as manufacturing trucks, tower buildings, ships, trams, furniture, mechanical parts, precision machining, etc. And 6063 is mainly used for doors and windows material and other extrusion profiles with aluminum tubes, aluminum rods, aluminum profiles. Heat sink always uses alloy 6063, because 6063 has high thermal conductivity. Comparison of 6061 and 6063 properties:
