material.halowerk.comConductor mass is calculated from nominal cross-section, core count and length against the material density; for a nominal cross-section this is exact and independent of stranding. Total cable mass and the copper share are returned as a range derived from published manufacturer weight tables per cross-section band, not as a type-test value. Insulation, filler and armour are not modelled individually.

The spread between low and high is wide and real: content depends on board generation, manufacturer and how much of the assembly is included. This is a planning estimate for sorting and pre-valuation, not an assay, not a settlement basis and not a substitute for a sampled analysis. Values are only calculated when price_eur_per_g is supplied by the caller; no metal price is retrieved or resold here.

}material.halowerk.comPacks items into parcels by descending weight, first fit, within a maximum parcel weight and an optional maximum girth, prices each parcel with the cheapest matching bracket of the supplied rate table and compares the total against single shipment. The rate table is caller data: no carrier tariff is stored or redistributed. First fit is a heuristic, not a proven optimum.

}material.halowerk.comUses the geometric AWG definition, so results are exact for solid round conductors. Mass per metre and resistance follow from the material density and resistivity at 20 degrees Celsius; stranded conductors carry roughly two to five percent more mass and resistance per metre than the same nominal size and are not modelled separately. Supply either awg or cross_section_mm2, not both. Sizes 4/0 through 40 AWG are covered.

Discovery comes from configured registries. Endpoint checks record responses, not task success. Older snapshots retain less detail. Customer usage, commercial terms and task evaluations require additional evidence.
