Start with Northline, keep AlloyWorks as the backup
For 2,000 kg of 6061-T6 aluminum sheet, Northline meets the 10-day delivery window and the €3.20/kg delivered-price ceiling. It offers the lowest delivered cost among the suppliers that meet both requirements.
The comparison
Northline: €3.10/kg delivered, 7 days, 500 kg minimum. AlloyWorks: €3.18/kg delivered, 9 days, 1,000 kg minimum. Harbor Metals: €2.96/kg delivered, 18 days, 2,000 kg minimum; cheaper, but outside the delivery window.
The recommendation
Northline totals €6,200 before VAT, €160 below AlloyWorks. Ask Northline to confirm the 7-day delivery date and provide the EN 10204 3.1 material certificate before placing an order. Keep AlloyWorks available if either confirmation falls through.
Compared the three quotes with the supplier catalog and purchasing rules through connected tools. Certificate availability and delivery still require supplier confirmation.
