Kev them nqi
| Cov khoom siv kos duab | Kwv yees% | Kev piav qhia |
|---|---|---|
| Cov khoom nyoos | 60-70% | Copper + nickel nqi, khi rau LME yav tom ntej |
| Kev tsim khoom | 15-20% | Melting, casting, extrusion, txias pilgering, kos duab, annealing |
| Kev xeem zoo | 3-5% | Eddy tam sim no, hydrostatic, tensile / hardness kuaj, PMI |
| Ntim | 3-8% | Ntoo crates, kawg hau, VCI, strapping, pallets |
| Thib peb-kev tshuaj ntsuam xyuas (yog tias xav tau) | 2-5% | BV, SGS, Lloyd's, DNV, thiab lwm yam. |

Tus nqi raw khoom
C71500 muaj kwv yees li 70% tooj liab thiab 30% npib tsib xee. Ob leeg tau pauv pauv ntawm kev sib pauv khoom thoob ntiaj teb.
| Hlau | Kwv yees li % hauv C71500 | Tus nqi cuam tshuam |
|---|---|---|
| Copper (Cu) | ~70% | Siab |
| Nickel (Ni) | ~30% | Siab heev (nickel kim dua tooj liab) |
Nickel yog tus nqi tseem ceeb ntawm tus tsav tsheb.C71500 muaj 30% npib tsib xee, thaum C70600 tsuas muaj 10% npib tsib xee. Qhov no yog vim li cas C71500 yog 25-40% kim dua C70600.
Yog vim li cas tsis yog -Standard Sizes raug nqi ntau dua
| Hom Loj | Kev cuam tshuam rau tus nqi | Yog vim li cas |
|---|---|---|
| Qhov ntau thiab tsawg (1/2", 3/4", 1", 0.065" phab ntsa) | qis | High ntau lawm ntim, npaj khoom |
| Tsis yog - qauv OD lossis phab ntsa thickness | Siab dua (20-50% premium) | Yuav tsum tau kev cai tooling los yog zeb khiav |
| me me OD (<6mm) or very large OD (>4") | Siab dua | Cov khoom siv tshwj xeeb tsim khoom xav tau |
| Nyias phab ntsa (<0.5mm) | Siab dua | Ntau nyuaj rau tsim, siab dua qhov tsis lees paub |
Thaum twg ua tau, txiav txim qhov ntau thiab tsawg. Qhov ntau thiab tsawg ntawm kev cai muaj, tab sis cia siab tias yuav raug nqi ntau dua thiab siv sij hawm ntev dua.
Vim li cas Me Me thiaj li raug nqi ntau dua ib Meter
| Order Quantity | Tus nqi txheeb ze ib 'meter' | Yog vim li cas |
|---|---|---|
| Tag nrho cov thawv ntim (20ft lossis 40ft) | Baseline (qis tshaj) | Tsau tus nqi kis thoob qhov ntim loj |
| 500-2000 kg | +15-30% | Ib nrab thawv, tus nqi tuav ntau dua |
| 100-500 kg | +30-60% | Txiav lengths, kev cai crating, teeb nqi |
| Hauv qab 100 kg (piv txwv) | +100-200% | Kev txiav txim yam tsawg kawg nkaus, tus nqi ua haujlwm siab ib kg |
Consolidate ntau yam khoom rau hauv ib qho kev txiav txim. Order standard lengths (6m / 12m) es tsis txhob txiav lengths. Npaj ua ntej kom tsis txhob muaj kev xaj xwm txheej ceev me me.
Ua li cas cuam tshuam tus nqi
| Temper / Tiav | Tus nqi txheeb ze | Thaum xaiv |
|---|---|---|
| Annealed (mos / O60 / O61) | Lub hauv paus | Rau khoov, flaring, raj expansion |
| Lub teeb kos (H55) | +5-10% | Rau cov yeeb nkab ncaj khiav yuav tsum muaj zog |
| Cov khoom siv (H80) | +10-15% | Rau siab - cov ntawv thov siab |
| Kev ntxhov siab (HR50) | +10-15% | Thaum seem kev ntxhov siab yuav tsum tau txo qis |
| Polished tiav | +15-30% | Rau qhov pom kev teeb tsa lossis qhov chaw tiv thaiv kab mob |
| Mill tiav (raws li -kos) | Lub hauv paus | Rau feem ntau cov ntawv thov kev lag luam |
Order lub temper uas phim koj fabrication xav tau. "Kev npau taws siab tsis yog ib txwm zoo dua" - kev npau taws hnyav dua yog qhov nyuaj rau khoov thiab tej zaum yuav xav tau annealing ua ntej tsim.
