About the Material

Aluminum is one of the most commonly used metals in the world because of its excellent strength-to-weight ratio, low cost, and recyclability. Fictiv offers multiple aluminum alloys.

Our standard alloy on platform is 6061, a versatile and easy-to-machine metal. It is corrosion-resistant, non-magnetic, and heat treatable.  

7075 Aluminum is a hard, high strength alternative to 6061 Aluminum . It is often used for parts in high-stress applications, and is also corrosion-resistant, non-magnetic and heat treatable.

Also known as jig plate or cast tool, MIC6 is a cast aluminum alloy that is great for tight tolerance applications due to it being stress-relieved. It is most commonly used in precision machine tables and tooling. MIC6 is non-magnetic and not heat treatable.

Cost Saving Tip

To reduce costs, limit the number of part setups, the number of inspection dimensions or tight tolerances, and deep pockets with small radii.

If surface finish is not a concern, you may design your part to be made from the closest stock thickness, specified in a drawing.
