美国稀土危机爆发:库存仅够数月,航空发动机及芯片制造面临停摆
Sou Hu Cai Jing· 2026-02-26 13:49
Core Insights - The aerospace and semiconductor supply chain is facing a critical shortage of rare earth elements, particularly yttrium and scandium, which are essential for advanced manufacturing and defense technologies [1][4] Group 1: Yttrium - Yttrium is crucial for special coatings that prevent jet engines and industrial turbines from melting at extreme temperatures [3] - The price of yttrium has surged approximately 60% since the reported shortage began last year, now being nearly 70 times higher than a year ago [3] - Due to supply constraints, two North American companies producing high-temperature coatings have temporarily halted production, prioritizing large clients like engine manufacturers over smaller and overseas customers [3] Group 2: Scandium - The shortage of scandium raises concerns about potential disruptions in the production of next-generation 5G chips, as it is used in fuel cells, specialized aluminum alloys, and advanced chip manufacturing processes [4] - Major U.S. chip manufacturers rely on scandium for components in nearly every 5G smartphone and base station [4] - The U.S. currently lacks domestic scandium production and has no fully alternative supply sources, with estimates suggesting that existing inventories may last only a few months [4] Group 3: Broader Implications - The current supply squeeze highlights how limited export controls on niche minerals can impact high-value industries, with yttrium and scandium's absence potentially leading to billions of dollars in production line shutdowns [5] - Delays and uncertainties in export licensing can trigger price surges, supply rationing, and strategic anxiety among U.S. manufacturers [5] - The situation emphasizes that reliance on critical minerals is not just a trade issue but also a national security concern [5]

新春走基层丨一个人的林海雪原 他踏上这条风雪巡线路快14年了
在内蒙古东北部的大兴安岭深处,冬季漫长而严寒,极端气温可达-40℃以下。与外界联系,主要靠电话和网络。网络维护员柴瑞峰负责的片区内有6000余 名居民,还驻有消防救援机动队伍和森林资源管护站。近14年来,他独自踏遍了1.3万平方公里的林海雪原,守护着106个基站、50多个瞭望塔以及800多公 里的光缆。日前,总台新春走基层记者跟随他走进林海,记录下了极寒环境中一个人一台车的风雪巡线路。 柴瑞峰:平常如果下雪的话,被雪盖住,我们这个基站它就无法正常运行了。冬天的时候扫主要的这个通信(网)站,十天半个月就得扫一次。 天刚蒙蒙亮,中国电信呼伦贝尔分公司的网络维护员柴瑞峰就准备出发,开始一天的巡检工作。担心前一晚的降雪压坏设备,今天,他要去林区深处的几处 基站和山顶瞭望塔看看。这些基站无固定市电供应,全靠光伏板维持运转,进入冬季,积雪、低温都会影响光伏板,严重时会造成线路冻裂,因此,巡检工 作格外重要。 记者帮着柴瑞峰一起推车,但一番努力后,还是没能把车推出雪坑。柴瑞峰拿来工具,开始铲雪。 快速清扫完基站积雪,确认设备正常后,柴瑞峰驱车前往下一站——山顶瞭望塔。一路上,既有厚厚的冰道,也有暗藏的松软雪层。尽管柴瑞峰一 ...

Core Views - The article discusses the increasing regulatory pressure on Huawei and ZTE in Europe, particularly in Germany, where there are moves to exclude these companies from telecommunications networks due to security concerns [2][3][7]. Regulatory Developments - The European Commission has urged member states to gradually exclude Huawei and ZTE from their telecom networks, citing security risks [2]. - Germany's Federal Network Agency (BNetzA) has expanded the definition of "critical" components to include the entire Radio Access Network (RAN), which could lead to stricter regulations against Huawei [7][8]. Huawei's Position - Huawei argues that the gNodeB, a component of the 5G network, should not be classified as part of the core network, claiming it does not control traffic or manage user profiles [3][4]. - Despite Huawei's claims, the perception of it as a "high-risk supplier" persists, and its influence in the European market remains significant, providing technology for about 25% of wireless access points in Europe [3][10]. Market Impact - Excluding Huawei from the German market could cost approximately €2.5 billion (around $2.9 billion), with Deutsche Telekom alone spending about €300 million (approximately $347 million) annually on its RAN [10]. - Deutsche Telekom and Vodafone are reportedly preparing for stricter regulations by introducing new RAN suppliers, indicating a shift away from reliance on Huawei [11]. Competitive Landscape - Huawei currently supplies about 60% of Germany's 5G base stations, with Ericsson and Nokia sharing the remaining market [10]. - The competitive dynamics are shifting as Deutsche Telekom plans to replace Huawei equipment with Nokia and Fujitsu products, while Vodafone has also introduced Samsung as a new supplier [11].
