KEY WORD: al6061, UNS A96061; ISO AlMg1SiCu; Aluminium 6061-T6, AD-33 (Russia); AA6061-T6; 6061T6, UNS A96061; ISO AlMg1SiCu; Aluminium 6061-T651, AD-33 (Russia); AA6061-T651.

This allows it to be used in heavy duty structures and marine environments. The 6061 grade is the most widely used aluminum sheet and plate grade available for all types of fabrication projects.

Aluminum 6061 sheet/plate composition (For Reference)

6061 aluminum sheet tensile strength range 20 to 42 KSI. Conforms to AMS QQ-A- 250/11 and ASTM B209.

The general purpose 6061 Aluminum Sheet & Plate is heat treatable, resists cracking due to stress, and is easy to weld and machine, but limited on formability.

6061 aluminum properties

The welding capability of this product is great, allowing any method of welding to be used. Annealing can be performed, which will put it in a state to be easily cold worked. Any methods of cold working can be used for stamping, drilling, bending, deep drawing, tapping, and cutting.

When annealing this metal, it’s recommended that it be placed in 775 degrees F for between two and three hours, followed by a steady drop in the temperature by 50 degrees each hour, until it is down to 500 degrees F. Air cooling should be allowed afterward.

Other methods of heat treatment that can be used include solution heat treating, aging precipitation heat treating, and hot working.

Aluminum 6061 sheet applications include a wide variety of products from medical assemblies, aircraft construction to structural components. 6061 t6 aluminum sheet has a high strength to weight ratio making it ideal for any application where parts need to be light.

Alloy 6061 coils and sheets are the most versatile of the heat treatable aluminum alloys. Though less strong than most of the 2xxx and 7xxx alloys, 6061 aluminum provides an extensive range of mechanical properties and corrosion resistance and can be fabricated by many of the commonly used practices.

In the “O” temper or annealed condition, alloy 6061 has good formability. In the T4 condition, fairly severe forming can be done; whereas, in the T6 condition, properties may be obtained by artificial aging.

Welding

6061 is highly weldable, for example using tungsten inert gas welding (TIG) or metal inert gas welding (MIG). Typically, after welding, the properties near the weld are those of 6061-T4, a loss of strength of around 40%. The material can be re-heat-treated to restore near -T6 temper for the whole piece. After welding, the material can naturally age and restore some of its strength as well.

Most strength is recovered in the first few days to a few weeks. Nevertheless, the Aluminum Design Manual (Aluminum Association) recommends the design strength of the material adjacent to the weld to be taken as 165 MPa/24000 PSI without proper heat treatment after the welding. Typical filler material is 4043 or 5356.

Extrusions

6061 is an alloy used in the production of extrusions—long constant–cross-section structural shapes produced by pushing metal through a shaped die.

Forgings

6061 is an alloy that is suitable for hot forging. The billet is heated through an induction furnace and forged using a closed die process. This particular alloy is suitable for open die forgings. Automotive parts, ATV parts, and industrial parts are just some of the uses as a forging.

Aluminum 6061 can be forged into flat or round bars, rings, blocks, discs and blanks, hollows, and spindles. 6061 can be forged into special and custom shapes.

Castings

6061 is not an alloy that is traditionally cast due to its low silicon content affecting the fluidity in casting. It can be suitably cast using a specialized centrifugal casting method. Centrifugally cast 6061 is ideal for larger rings and sleeve applications that exceed limitations of most wrought offerings.

Aluminum 6061 density

The density of 6061 aluminum alloy is 2.7 g/cm3 (0.0975 lb/in3), or about the same as pure aluminum metal.

6061 aluminum vs 7075?

Though there are many different types of aluminum, the two most popular are 6061 aluminum and 7075 aluminum.

What is the different between 6061 aluminum and 7075 aluminum?

This comparison will be done by looking at the following features of the two metals. Weight, strength, conductivity, durability, and machining.

Strength makes the primary difference between 6061 and 7075 aluminum. For example, 7075 exhibits very high strength-to-weight ratio. In fact, 7075 provides the greatest strength available in aluminum bar.

It is widely used in aircraft applications where light weight plus strength are required, not to mention a high exposure to heat.

6061 Aluminum is more commonly used in aircraft construction due to its low weight and high strength. The conductivity of this type of aluminum is lower than that of the other variety which leads to a less efficient power transfer if it is used in electric currents.

7075 Aluminum has higher strength and lower weight than 6061 aluminum but has lower hardness. This means it doesn’t hold up as well over time as 6061 aluminum does but can better withstand high temperatures.

While 6061 is used in products that need to be lighter weight, if you’re using it for a product that needs to be stronger, then you would want to go with 7075.

What is the difference between 6061 aluminum and 6063?

6063 is another commonly used grade of aluminum and is often compared to 6061. Both 6061 and 6063 are made up of magnesium and silicon as their primary alloying elements, meaning they exhibit many of the same properties.

The difference between 6061 and 6063 is mainly in the end use. 6063 is a common grade used for custom extrusions. Its high corrosion resistance and good formability make it one of most joinable alloys. 6061 features higher strength (tensile strength range is 20 to 42 KSI) than 6063.
