剩者为王，印尼镍项目知多少。2024年镍价承压下行，11月1日电解镍价格为12.4万元/吨，同比下降13%。持续低迷的镍价对行业供给已造成负面影响，嘉能可、必和必拓、埃赫曼等多家企业已宣布减产或终止镍资源投资。我们认为当前在印尼能保持运营并持续扩产的企业已是剩者为王。考虑到美联储进入降息周期、中国出台多项经济刺激政策，我们认为镍行业需求有望保持中高速增长。当前中资企业在印尼已形成红土镍矿冶炼产业集群，权益在产产能超过50万吨，规划权益产能合计超90万吨。建议关注优质镍资源 给华友钴业、格林美、中伟股份、力勤资源、伟明环保等企业带来的竞争优势。

Sinter plants turns raw materials such as iron ore, coal, and scrap steel into crude steel by the blast furnacebasic oxygen furnace (BF-BOF) method. Sinter plants are a part of integrated steel plants. The output of a sinter plant is called a sinter, which is then crushed, cooled and screened for any dust which is primary feed for steel production.

Metal additive manufacturing is the process of manufacturing metal components by laying down layers of metal-based materials based on the shape of the object. Additive manufacturing or 3D printing is a process of making 3D parts by successively laying down layers of materials. Each of these layers is a thinly sliced horizontal cross-section of the final object. The structures and shapes of the objects or components are created with the help of a digital format. The current report discusses metal additive manufacturing equipment and devices.

Aluminum is much lighter than steel and has numerous advantages over other materials, such as flexibility, the automotive sector's largest segment is increasingly focusing on using aluminum rather than steel and iron to produce components and parts using die-casting machinery.

The global demand for handheld metal detectors has been on the rise in recent years, driven by a combination of factors. The primary driver of this increased demand is the growing concern over security threats and the need for enhanced security measures in public spaces, such as airports, schools, and government buildings. Many organizations and institutions have implemented stricter security protocols, including the use of handheld metal detectors to screen individuals for weapons and other prohibited items.

低空经济建设如火如荼，镁材料有望在低空经济中发挥重要作用：低空经济涵盖基础设施建设和低空航空器。国家推动基础设施建设，“十四五”规划支持金属零部件制造和低空经济发展，地方政府积极扩展市场。非管制空域的明确将扩大低空经济活动范围，通用机场建设和低空航空器渗透率预计将快速增长。预计 2025 年全球 eVTOL 将开始商业化，无人机在物流和生产中将发挥重要作用。与传统材料相比，镁的质量轻、低成本、高储备特性使得镁材料有望解决低空经济建设原材料成本高、运转效率低的困境，发挥重要作用。
