by John Winebrenner When it comes to machining aluminum, it’s not a simple task. There are many grades of aluminum, all of which have different recommended machining techniques. This tool tip helps break down some of the different grades of aluminum and our recommendations for tooling and surface feet per minute. ![]() 1100 Grade Aluminum This grade of aluminum is commercially pure aluminum and easy to machine though very ductile and difficult to control chips. SFM = > 1000 2024 & 6061 Grades Aluminum These grades are high strength and heat treatable aluminum alloys. They are very commonly used in Aircraft, Recreation, and Automotive body components. SFM = > 600 7050 & 7075 Grades Aluminum These grades are some of the highest strength aluminum alloys available. They are used in the manufacturing of Aircraft and Marine Vehicles.
Cast Aluminum A319 – 5% Silicon Standard Tooling can be used very effectively. A356 – 7% Silicon Standard Tooling can be used very effectively. A380 – 10.5% Silicon PCD Tooling is the preferred tool for this material. TiB2 or ZrCN coatings must be used if using a carbide tool. A390 – 17% Silicon PCD Tooling or Coating is the only tool material that will effectively machine this grade of Aluminum. Lower SFM is preferred for this grade, < 1000 SFM.

The root of a tap is the surface at the bottom of the thread-form that connects adjacent thread flanks and is expressed as a width or as a diameter. The term root diameter is also called minor diameter, it’s one of those things, you say rain and I say precipitation, meaning the same thing... |
