style="font-size:16px"><strong>제품 응용:</strong></span></p> <p align="justify">1. 스칸듐(Sc)은 알루미늄 합금의 강력한 결정립 미세화제 및 재결정 억제제 역할을 하며, 결정립 미세화를 촉진하고 재결정 온도를 250°C - 280°C까지 높일 수 있습니다. 이는 합금의 구조와 특성에 상당한 영향을 미치며 강도, 경도, 용접 성능, 내식성, 초가소성 등을 크게 향상시킵니다.</p> <p align="justify">2. 주로 항공우주 및 해군용 용접 하중 지지 구조 부품뿐만 아니라 알칼리 부식성 매체 환경용 알루미늄 합금 파이프, 철도 오일 탱크 및 고속 열차의 주요 구조 부품에 사용됩니다.</p> <p align="justify">3. 스칸듐(Sc)의 녹는점은 1539°C이고, 알루미늄의 녹는점은 660°C입니다. 녹는점의 실질적인 차이를 감안할 때 스칸듐은 모합금 형태로 알루미늄 합금에 첨가되어야 합니다. 스칸듐 마스터 합금은 스칸듐 함유 알루미늄 합금을 생산하는 핵심 원료입니다.</p> <p> </p> <p align="justify"><span style="font-size:16px"><strong>기술적 장점:</strong></span></p> <p align="justify">1. 급속냉각주조를 통해 제품의 조성이 균일해집니다. 디 알<sub>3</sub>Sc 입자는 뭉침 없이 분산 분포되어 있으며 크기가 20μm 미만입니다.</p> <p align="justify">2. Fe, Si, Ca 등의 불순물 함량이 낮고 순도가 높은 제품이며, 산소함유량이 50ppm이하입니다.</p></div><div class="pnbar cl"><p>이전 : <a href="#">없음</a></p><p>다음 : <a href="/news-detail/high-purity-lanthanum-metal">고순도 희토류 금속 시리즈 - 고순도 란타늄 금속(La)</a></p></div></div></div><div class="show-list-6"><div class="wp1200"><h2>관련 상품 카테고리</h2><ul><li><a href="https://hnrem.com/products_list/yttrium-metal-powder">이트륨 금속 분말</a></li><li><a href="https://hnrem.com/products_list/terbium-metal-complexes">테르븀 금속 착물</a></li><li><a href="https://hnrem.com/products_list/Chinese-calcium-magnesium-alloy">중국 칼슘 마그네슘 합금</a></li><li><a href="https://hnrem.com/products_list/emc-metals-scandium">EMC 금속 스칸듐</a></li><li><a href="https://hnrem.com/products_list/aluminum-scandium-alloys">알루미늄 스칸듐 합금</a></li><li><a href="https://hnrem.com/products_list/dysprosium-non-metal">디스프로슘 비금속</a></li><li><a href="https://hnrem.com/products_list/yttrium-stabilized-zirconium-oxide-powder">이트륨 안정화 산화지르코늄 분말</a></li><li><a href="https://hnrem.com/products_list/Terbium-ESPI-metals-factory">테르븀 ESPI 금속 공장</a></li><li><a href="https://hnrem.com/products_list/yttrium-oxide-spray-dried-powder">이트륨 산화물 분무 건조 분말</a></li><li><a href="https://hnrem.com/products_list/Yttrium-stabilized-zirconia-powder-factory">이트륨 안정화 지르코니아 분말 공장</a></li><li><a href="https://hnrem.com/products_list/Yttrium-metal-uses-factory">이트륨 금속을 사용하는 공장</a></li><li><a href="https://hnrem.com/products_list/Scandium-aluminum-alloy-for-sale-factory">스칸듐 알루미늄 합금 판매 공장</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="심벌 마크"></div><div class="foot-contact"><div><p><span style="font-size: 24px;"><strong>후난희토류유한회사</strong></span></p><p>주소: 중국 후난성 창사시 류양경제기술개발구 샹타이로 18호.</p></div><div><p>모바일/왓츠앱: <a href="https://api.whatsapp.com/send?phone=8615111328177" target="_blank">+86 15111328177</a></p><p>전화: <a href="tel:8619397988799" target="_blank">+86 19397988799</a></p><p>팩스: +86 731 85661506</p><p>이메일: <a href="/cdn-cgi/l/email-protection#e685898892878592a68e8894838bc885898b"><span class="__cf_email__" data-cfemail="781b17160c191b0c3810160a1d15561b1715">[email protected]</span></a></p></div></div></div><div class="foot-right"><h5>우리를 팔로우하세요</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">회사 소개</a></li><li><a href="/product">제품</a></li><li><a href="/quality-control">품질 관리</a></li><li><a href="/news">소식</a></li><li><a href="/research-service">연구 및 서비스</a></li><li><a href="/contact-us">문의하기</a></li><li><a href="https://blog.hnrem.com/" target="_blank">블로그</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>저작권 © 후난희토류주식회사 All Rights Reserved | <a href="/privacy-policy" target="_blank" rel="nofollow">개인 정보 보호 정책</a> | <a href="/terms-and-conditions" target="_blank" rel="nofollow">이용약관</a></p></div></div></div><div id="huake-side-bar" class="huake-side-bar"><a href="https://api.whatsapp.com/send?phone=+86 15111328177" rel="nofollow" target="_blank" aria-label="WhatsApp" class="text"><img src="/static/site/images/wechat.png" alt="왓츠앱"><span>왓츠앱</span></a><a href="#" rel="nofollow" target="_blank" aria-label="Inquiry" class="text"><img src="/static/site/images/facebook1.png" alt="페이스북"><span>페이스북</span></a><a href="/cdn-cgi/l/email-protection#3a5955544e5b594e7a5254485f5714595557" rel="nofollow" target="_blank" aria-label="Email" class="text"><img src="/static/site/images/email.png" alt="이메일"><span>이메일</span></a></div><div id="gotop"><i class="qico qico-up"></i></div><script data-cfasync="false" src="/cdn-cgi/scripts/5c5dd728/cloudflare-static/email-decode.min.js"></script><script type="text/javascript" src="/static/site/js/js.js"></script><script type="text/javascript" src="/static/site/js/jquery.counterup.js"></script><script type="text/javascript" src="/static/site/js/jquery.fancybox.js"></script><script src="/static/site/layui/layui.js"></script><script src="/static/site/js/form.js"></script><script> $(function () { $('.nav>ul>li').eq(3).addClass('active').siblings().removeClass('active');
