What the mill checks
Four Numbers That Decide Whether This Ships
1 Gauge at nine points
Thickness is measured across the full width, not at one spot. A coil that is on gauge at the edge and 0.04 mm light at the center will still pass a lazy check.
2 Mechanical properties per heat
Tensile, yield and elongation pulled from the actual heat, not from a nominal table. On request the values are reported on a 3.1 certificate with the heat number; a 2.2 statement is available where that is all your file requires.
3 Surface under raking light
Roller marks, oil stain, scratch and edge burr are checked before packing. Coated product is checked for film build and color delta.
4 Packing for the voyage
Kraft plus PE film, steel-strapped pallet, edge protector, desiccant. Photos of the strapping and seal number sent before sailing.

Before you ask
Special Copper Alloys — Questions That Come Up
Which alloy grades and tempers can you supply in Special Copper Alloys?
Grades: C17200 · C71500 · C18150 (CuCrZr). Tempers: Soft · Hard · Age-hardened. If your grade is not on that list it is usually a mill enquiry rather than a no — send it and we will say which one, in the first reply.
What sizes does Special Copper Alloys cover?
Ø 1 – 200 mm thick, — wide, Up to 4,000 mm. Quoted against ASTM B194 · B151 · B747. Where a drawing names two standards, we confirm which one governs before the order, not after the inspection report.
What certificate comes with Special Copper Alloys?
EN 10204 3.1 with the heat analysis and mechanical results, or 2.2 where that is what your file requires. Third-party inspection by SGS or BV is available. The certificate type is confirmed on the quotation, before you commit.
What is the minimum order for Special Copper Alloys?
2 t for stocked flat-rolled. Below that we consolidate into a shared container, so the order still ships — it just waits for a sailing.
How fast do you quote Special Copper Alloys?
Quotation within 24 hours on working days. We price grade, temper, gauge and quantity in one reply, and say which standard governs if the drawing names two.
Where does the Special Copper Alloys come from?
From audited mills across 6 regions — Gongyi, Wuxi / Changzhou, Zouping / Binzhou, Foshan, Ningbo / Taizhou, Luoyang — each chosen for the process this product needs. You deal with one party; the mill allocation is our job, not yours.
