</p> </div> <p align="justify"><span style="font-size:16px"><strong>Produktanwendungen:</strong></span></p> <p align="justify">1. Scandium (Sc) dient als starker Kornverfeinerer und Rekristallisationsinhibitor für Aluminiumlegierungen, der die Kornverfeinerung fördern und die Rekristallisationstemperatur um 250 °C bis 280 °C erhöhen kann. Dies hat erhebliche Auswirkungen auf die Struktur und die Eigenschaften der Legierung und verbessert deren Festigkeit, Härte, Schweißleistung, Korrosionsbeständigkeit, Superplastizität usw. erheblich.</p> <p align="justify">2. Es wird hauptsächlich in geschweißten tragenden Strukturkomponenten für Luft- und Raumfahrt- und Marineanwendungen sowie in Aluminiumlegierungsrohren für Umgebungen mit alkalischen korrosiven Medien, Eisenbahnöltanks und wichtigen Strukturkomponenten von Hochgeschwindigkeitszügen verwendet.</p> <p align="justify">3. Der Schmelzpunkt von Scandium (Sc) beträgt 1539 °C, während der von Aluminium 660 °C beträgt. Aufgrund der erheblichen Unterschiede in ihren Schmelzpunkten muss Scandium der Aluminiumlegierung in Form einer Vorlegierung zugesetzt werden. Scandium-Vorlegierung ist der Schlüsselrohstoff für die Herstellung scandiumhaltiger Aluminiumlegierungen.</p> <p> </p> <p align="justify"><span style="font-size:16px"><strong>Technische Vorteile:</strong></span></p> <p align="justify">1. Durch das schnelle Abkühlen erhält das Produkt eine gleichmäßige Zusammensetzung. Der Al<sub>3</sub>Sc-Partikel sind ohne Agglomeration dispergiert verteilt und ihre Größe beträgt weniger als 20 μm.</p> <p align="justify">2. Das Produkt weist eine hohe Reinheit auf, weist einen geringen Gehalt an Verunreinigungen wie Fe, Si und Ca auf und der Sauerstoffgehalt beträgt weniger als 50 ppm.</p></div><div class="pnbar cl"><p>VORHER : <a href="#">Keiner</a></p><p>NÄCHSTE : <a href="/news-detail/high-purity-lanthanum-metal">Hochreine Seltenerdmetallserie – Hochreines Lanthanmetall (La)</a></p></div></div></div><div class="show-list-6"><div class="wp1200"><h2>Verwandte Produktkategorien</h2><ul><li><a href="https://hnrem.com/products_list/yttrium-metal-oxidation">Oxidation von Yttriummetall</a></li><li><a href="https://hnrem.com/products_list/Magnesium-zirconium-master-alloys-factory">Fabrik für Magnesium-Zirkonium-Vorlegierungen</a></li><li><a href="https://hnrem.com/products_list/terbium-dysprosium">Terbiumdysprosium</a></li><li><a href="https://hnrem.com/products_list/calcium-magnesium-alloy">Calcium-Magnesium-Legierung</a></li><li><a href="https://hnrem.com/products_list/Chinese-terbium-ESPI-metals">Chinesische Terbium-ESPI-Metalle</a></li><li><a href="https://hnrem.com/products_list/terbium-rare-earth-metals">Terbium, Seltenerdmetalle</a></li><li><a href="https://hnrem.com/products_list/Terbium-rare-earth-metals-factory">Fabrik für Terbium-Seltenerdmetalle</a></li><li><a href="https://hnrem.com/products_list/Terbium-metal-complexes-factory">Fabrik für Terbium-Metallkomplexe</a></li><li><a href="https://hnrem.com/products_list/Terbium-powder-factory">Terbiumpulverfabrik</a></li><li><a href="https://hnrem.com/products_list/Yttrium-metal-company-factory">Fabrik des Yttrium-Metallunternehmens</a></li><li><a href="https://hnrem.com/products_list/Yttrium-metal-China-factory">Yttrium-Metall-China-Fabrik</a></li><li><a href="https://hnrem.com/products_list/Dysprosium-metal-uses-factory">Dysprosiummetall wird fabrikmäßig verwendet</a></li></ul></div></div><div id="footer"><div class="wp"><div class="foot-left"><div class="foot-logo"><img src="/static/upload/logo/1704872448825766.png" alt="Logo"></div><div class="foot-contact"><div><p><span style="font-size: 24px;"><strong>Hunan Rare Earth Co., Ltd.</strong></span></p><p>Adresse: Nr. 18 Xiangtai Road, Wirtschafts- und Technologieentwicklungszone Liuyang, Stadt Changsha, Provinz Hunan, China.</p></div><div><p>Mobil / WhatsApp: <a href="https://api.whatsapp.com/send?phone=8615111328177" target="_blank">+86 15111328177</a></p><p>Tel: <a href="tel:8619397988799" target="_blank">+86 19397988799</a></p><p>Fax: +86 731 85661506</p><p>E-Mail: <a href="/cdn-cgi/l/email-protection#2a4945445e4b495e6a4244584f4704494547"><span class="__cf_email__" data-cfemail="dfbcb0b1abbebcab9fb7b1adbab2f1bcb0b2">[email protected]</span></a></p></div></div></div><div class="foot-right"><h5>Folgen Sie uns</h5><div class="share"><a href="https://www.facebook.com/profile.php?id=61568305870759" aria-label="facebook" rel="nofollow" target="_blank"><i class="qico qico-facebook"></i></a><a href="https://www.pinterest.com/hngcxt/" aria-label="pinterest" rel="nofollow" target="_blank"><i class="qico qico-pinterest"></i></a><a href="https://www.linkedin.com/company/105001164/admin/dashboard/" aria-label="linkedin" rel="nofollow" target="_blank"><i class="qico qico-linkedin"></i></a><a href="https://www.youtube.com/channel/UC6jEc2jn5rlkRkvx1_xYHow" aria-label="youtube" rel="nofollow" target="_blank"><i class="qico qico-youtube"></i></a></div></div></div><div class="foot-nav"><div class="wp"><ul><li><a href="/about-us">Über uns</a></li><li><a href="/product">Produkte</a></li><li><a href="/quality-control">Qualitätskontrolle</a></li><li><a href="/news">Nachricht</a></li><li><a href="/research-service">Forschung & Service</a></li><li><a href="/contact-us">Kontaktieren Sie uns</a></li><li><a href="https://blog.hnrem.com/" target="_blank">Blog</a></li><!-- <li><a href="sitemap.html">Sitemap</a></li> --></ul></div></div><script data-cfasync="false" src="/cdn-cgi/scripts/5c5dd728/cloudflare-static/email-decode.min.js"></script><script type="text/javascript" src="/static/site/cookie-policy/cookie-policy.js" defer=""></script><div class="copyright"><div class="wp"><p>Copyright © Hunan Rare Earth Co., Ltd.
