A higher-strength aluminum alloy often used where strength-to-weight matters. It is not interchangeable with every aluminum cutting-data table.
Machining behavior
The alloy is generally machinable, but tool geometry, coating and heat control affect finish and tool life.
What to verify before calculating
- Exact alloy, grade and material condition.
- Tool material, coating, diameter and flute geometry.
- Operation and radial/axial engagement.
- Machine spindle/feed limits and setup rigidity.
- Coolant and chip evacuation.
Using the calculator
Verify alloy/temper and the exact cutter recommendation rather than transferring a generic 6061 setting. Once the source cutting speed and chip-load data are established, use the calculators to convert those values into RPM, feed, feed per revolution and MRR.

Important limitation
A material name alone does not define a production cutting condition. Treat any generic value as a starting reference and give priority to the exact tool manufacturer recommendation and your proven shop data.
