CNC Machined 6061 Aluminum

Xometry is trusted by thousands to deliver high-quality machining using aluminum alloy 6061. Aluminum 6061 is one of the most common materials used for CNC Machining. Easily machined and lightweight, it is an ideal material for prototypes. It has excellent joining characteristics and accepts applied coatings easily. The natural finish of aluminum 6061 is light grey, and will shine where cut or milled. It combines relatively high strength with good workability and high resistance to corrosion. The T8 and T9 tempers offer better chipping characteristics compared to T6 temper. Aluminum 6061-T6511 is the specific temper for the most commonly used bar stock, and 6061-T651 for plate or sheet stock.

Xometry Supplies offers high quality, custom cut Aluminum 6061-T6 with free shipping and prices that are among the industry's lowest.

CNC Finishes

As-Milled

The finish option with the quickest turnaround. Parts are left with visible tool marks and potentially sharp edges and burrs, which can be removed upon request. Surface finish is comparable to 125 uin Ra finish.

Bead Blast

The part surface is left with a smooth, matte appearance.

Anodized (Type II or Type III)

Type II creates a corrosion-resistant finish. Parts can be anodized in different colors—clear, black, red, and gold are most common—and is usually associated with aluminum. Type III is thicker and creates a wear-resistant layer in addition to the corrosion resistance seen with Type II.

Powder Coat

This is a process where powdered paint is sprayed onto a part which is then baked in an oven. This creates a strong, wear- and corrosion-resistant layer that is more durable than standard painting methods. A wide variety of colors are available to create the desired aesthetic.

Overview: What is CNC?

Xometry's CNC Manufacturing Standards

  • Sharp edges will be broken and deburred by default. Critical edges that must be left sharp should be noted and specified on a print.
  • For features of size (Length, width, height, diameter) and location (position, concentricity, symmetry) +/- 0.005”.
  • For features of orientation (parallelism and perpendicularity) and form (cylindrical, flatness, circularity, and straightness) apply tolerances as follows:

0-12”

Tolerance of 0.005”

Angularity

+/- ½ degree

Over 12”-24”

Tolerance of 0.010”

Angularity

+/- ½ degree

Over 24"-36"

Tolerance of 0.015625" (1/64)

Angularity

+/- 1 degree

Over 36"-60"

Tolerance of 0.03125" (1/32)

Angularity

+/- 1 degree

Over 60"

Tolerance of 0.0625" (1/16)

Angularity

+/- 1 degree
