VT machining offers CNC Tapping for 1070 Aluminum (UNS A91070 / EN AW-1070A), typically supplied O / H14. Higher purity grade for conductivity and anodised finish.
CNC Tapping Notes for 1070 Aluminum
1070 Aluminum is ductile enough for form (roll) tapping, which gives stronger, chip-free threads; cut taps are used where the drawing or material condition requires.
For estimating, a 100 × 100 × 10 mm block of 1070 Aluminum weighs about 0.27 kg.

What surface finish is achievable on 1070 Aluminum with CNC Tapping?
Surface finish on 1070 Aluminum is controlled to your specification; we confirm the achievable Ra against your callout.
Does CNC Tapping 1070 Aluminum require dedicated tooling?
Most 1070 Aluminum machining work uses standard cutting tools and CNC programs; dedicated fixtures are made only when geometry or volume requires them.
What is CNC Tapping 1070 Aluminum and how is it done?
CNC Tapping 1070 Aluminum refers to rigid CNC tapping cuts internal threads in sync with spindle feed for precise, repeatable thread engagement. Applied to 1070 Aluminum — lightweight with excellent machinability — VT machining produces each part to your CAD drawing, selecting parameters from your tolerance, finish and quantity requirements.
Why is 1070 Aluminum a good choice for CNC Tapping?
1070 Aluminum is lightweight with excellent machinability, which makes it well suited to CNC Tapping. We tune the process to the alloy so the finished 1070 Aluminum machining part meets your dimensional and functional requirements.
How clean are the edges produced by CNC Tapping on 1070 Aluminum?
Machined 1070 Aluminum edges are clean and to specification; edge-break or deburring is added when your drawing calls for it.
Can VT machining make custom 1070 Aluminum parts to my drawing?
Yes. 1070 Aluminum machining is made to order from your CAD/2D drawing. Share your geometry, material grade, tolerance and quantity and we will confirm feasibility, lead time and pricing.
