In summary, the person is looking for suggestions on selecting an Aluminum grade that is cheaper, medium to very hard, highly machinable, and holds anodize well. Strength is not a major factor. One suggestion is to consider 6061-T6, which is commonly used for bicycles. However, if high hardness is needed, a more expensive and less machinable alloy, such as 7075, may be required.

Hi all, I'm looking for suggestions on selecting an Aluminum grade which fits the following criteria--

-The cheaper the better!
-Medium hard to very hard
-Highly machinable (I'd like to see chips, not strings.)
-Holds anodize well
-Strength is not particularly important

I have some ideas, but it's always nice to see some validation of those ideas without sharing exactly what they are. It'll boost my confidence that I made a good choice. Thanks in advance!

I believe bicycles are often 6061 or 7005.

If hardness isn't a huge priority, I'd look into something like 6061-T6. If you need high hardness though, I don't think you can get it without going to a fairly expensive, less machinable alloy (like 7075).
 

FAQ: What is the best Aluminum grade for my project?

1. What factors should be considered when selecting an aluminum grade?

When selecting an aluminum grade, it is important to consider the intended use of the metal, the required strength and durability, the environment it will be exposed to, and the cost. Other factors to consider may include corrosion resistance, formability, and weldability.

2. How do I determine the appropriate aluminum grade for my project?

The best way to determine the appropriate aluminum grade for your project is to consult with a materials engineer or conduct extensive research on the different grades available. Consider the specific properties and characteristics of each grade and how they align with the requirements of your project.

3. What are the most common types of aluminum grades used in various industries?

The most commonly used aluminum grades in various industries include 6061, 7075, and 2024. 6061 is a general-purpose grade with good formability and weldability, 7075 is a high-strength grade often used in aerospace and military applications, and 2024 is a high-strength grade with good machinability.

4. Can different aluminum grades be combined or alloyed together?

Yes, different aluminum grades can be combined or alloyed together to create new grades with unique properties. For example, 7075 and 2024 can be combined to create a high-strength alloy with good machinability.

5. How does the cost of aluminum vary between different grades?

The cost of aluminum can vary greatly between different grades depending on their properties and availability. In general, high-strength and specialized grades tend to be more expensive than general-purpose grades. Additionally, market demand and supply can also affect the cost of aluminum grades.
