Aluminum Extrusion & Profile Manufacturing worked example

Aluminum Billet Yield Calculator at 99% target billet recovery yield: a worked example

This scenario runs the aluminum billet yield calculator calculation on the strong side: 99% target billet recovery yield, with every other input held at its documented default. an extruder needs to compare actual billet recovery with the target yield for a profile run

The inputs for this scenario

  • Recovered good profile weight: 8,650 lb (unchanged)
  • Total billet input weight: 10,000 lb (unchanged)
  • Target billet recovery yield: 99 % (raised for this scenario; the documented default is 88)

Working through the calculation

  • Applying the documented formula (Actual billet-to-profile yield = recovered good profile weight ÷ total billet input weight × 100) to the inputs above produces each figure below.
  • At this operating point the engine returns 86.5 % yield for actual billet-to-profile yield, the number this scenario is built around.
  • At this operating point the engine returns 12.5 points for yield gap to target.
  • At this operating point the engine returns 8,650 lb for recovered good profile weight.
  • At this operating point the engine returns 10,000 lb for total billet input weight.

How this compares with the baseline

  • Against the tool's baseline example, where target billet recovery yield sits at 88% and the headline result is 86.5 % yield, this scenario lands almost exactly on the baseline at 86.5 % yield.
  • Use it at shift end or per billet lot to track scrap loss, compare dies, or qualify a new alloy/profile before quoting it. Treat this as a target state: the delta against the baseline quantifies what the improvement is worth before you commit to chasing it.

Results at a glance

  • Actual billet-to-profile yield: 86.5 % yield (headline result)
  • Yield gap to target: 12.5 points
  • Recovered good profile weight: 8,650 lb
  • Total billet input weight: 10,000 lb
