Materials Components Finishes & Marking    

Aluminum Flat & Round Bar Stock

Aluminum is corrosion resistant and light weight.

It has a lower structural stiffness than steel (about 1/3), which must be compensated for by thicker gauge.

Finish:

Powdercoat, No Finish or Grained Finish

Fasteners:

Typically, stainless steel fasteners are used with aluminum. However, in some cases, zinc-plated fasteners are used, depending on the application.

Additional Notes for Fasteners with Aluminum: Aluminum fasteners are very soft and therefore have low physical durability. As a result, we do NOT stock them. However, there are some applications where they are useful, such as parts that have service in corrosive liquids such as salt water. Other combinations of dissimilar metals can cause galvanic corrosion.

Stocked Aluminum alloy (Bar Stock) - for CNC Milling

We offer 5-axis and 3-axis vertical milling of bar stock in aluminum, as well as CNC turning of aluminum round bar stock.

Work holding is typically with the use of precision machine vices, chucks and clamps. With this service we can produce a wide variety of machined parts and enclosures.

Note: Aluminum Bar Stock is currently not available in Protocase Designer. Please contact your Account Manager for more information
