6061 aluminum plate is the typical choice for general-purpose applications. Silicon and magnesium are the primary alloying elements in this heat treatable aluminum alloy. It is widely utilized in structural applications due to its superior formability, weldability, and corrosion resistance. Despite the fact that it may not machine as well as 2024 or 7075, it is often utilized in machined part applications that do not require the greater strength levels found in 7075 and 2024.

 

One of the primary advantages of using 6061 aluminum tooling plate is its adaptability. It is suitable for a wide range of applications, including electronics and agriculture, storage tanks, hydraulic cylinders, pipes, construction, and even recreational goods. 6061 T6 aluminum sheet and related goods are popular choices for customers looking for a cost-effective option with excellent welding capability and the ability to be bent to their specifications. Another advantage of utilizing 6061 aluminum plate is that it is corrosion resistant, which is very useful if your products are frequently exposed to the elements, moisture, or extreme temperature variations.

 

6061 Aluminum Plate Uses

This aluminum plate, also known as a precision plate, is suitable for practically any application or general-purpose project. 6061 Alloy is suitable for the following projects:

Product categories include pipelines, welded assemblies, and architectural and building materials.
Freshwater Marine and Agricultural Applications
Recreation, Exercise Equipment, and Sports Goods
Electrical and Electronic Components
Furniture, Storage Tanks, and Chemical Equipment
Pneumatic and Hydraulic Cylinder Components

 

6061 Aluminum Plate Available

Because 6061 plate is a wrought product, it has better mechanical and physical qualities than cast plates. However, cast tool and jig plate remains the flattest aluminum plate product made. The 6061 precision plate is finished with a durable satin brush, making it simple to process and anodize. Precision plate provides 1/2 standard Aluminum Association thickness tolerances, as well as increased flatness tolerances for thicknesses up to 3.0" and widths up to 60.5". The improved thickness and flatness tolerances are only available in the 6061-T651 aluminum plate alloy.

FAQ

What is 6061-T651 aluminum and what does the "T651" designation indicate?

6061-T651 is an aluminum plate made primarily of silicon and magnesium. Because of its multiple advantages, it is very adaptable and used in a wide range of sectors. These characteristics include a high level of corrosion resistance, enough strength, and acceptable weldability. It is also cost-effective. The T-651 designates this alloy's temper. The temper is determined by the order in which basic treatments are applied to produce the different tempers. T-6 denotes that the product has been solution heat treated and then artificially aged. The additional numerals 51 show that the material was stretched after aging or cooling. The 6061 Aluminum plate provides ½ commercial plus side thickness tolerances and better flatness tolerances up to 4" thick.

 

Which industries commonly use 6061-T651 aluminum plates?

A variety of industries commonly use 6061-T651. It has several applications, including electrical and electronic components, athletic equipment, hydraulic cylinder components, pipelines, and construction. It is also employed in agricultural industries.

 

Can you discuss the machinability and formability of 6061-T651 aluminum plates?

Many charts evaluate 6061-T651's machinability as a C, however it performs far better. Between alloy improvement and machine tool progress, 6061 is a good machining alloy of aluminium employed in a wide range of general applications. Suitable for a variety of applications. Finally, 2024 and 7075 aluminum plates will machine faster and generate smaller chips. fitted the bill better. However, 6061 has good formability if you adhere to the recommended bend radius for the thickness.

 

Are there any limitations or environments in which 6061-T651 aluminum may not be suitable?

Although 6061-T651 aluminum is often recognized as a general-purpose metal aluminum plate, it is lightweight and has lower fatigue resistance than other choices, such as 2024. It should not be employed in areas with frequent tension stress, such as aircraft fuselages or wings.

 

What factors should be considered when selecting the thickness of 6061-T651 aluminum plates?

When choosing the thickness of your 6061-T651 aluminum plates, make sure to consider both the thickness and flatness tolerances required for your application. Most wholesalers stock 6061 T651 plate with all thickness tolerances on the positive side. However, this does not guarantee that the material will clean up to the nominal dimension; it simply provides the machinist a little more room to work with.
