Aluminum foil is a flexible, thin aluminum metal sheet, which is made by rolling pure aluminum metal into thin sheets followed by hardening it to endow barrier properties. It provides a strong barrier against air, moisture, and microorganisms, which increases the lifespan of the packaged products.

展望2025年，我们认为钢铁行业有三重因素有望促进行业格局改善。 供给端，政策限产+部分企业现金流压力推动行业供给加快出清。碳中和背景下， 政策端明确钢铁去产量为中长期基调，节能降碳要求有望加快落后产能出清，供给端 行业的兼并重组有望推动未来集中度的提升。

钢铁：3 月是传统旺季，建材端需求有望逐渐回暖，叠加汽车等行业支撑板 材端需求，钢价或受需求带动回暖，但需关注实际需求恢复情况；同时需关 注国内宏观政策和国外关税措施的对价格的影响。 铜：铜矿端持续偏紧，铜价下方有支撑；3 月是传统旺季，“两新”政策有望 刺激消费，若需求实现回升带动库存下降，铜价将有一定上行空间，需关注 国内宏观政策和实际需求数据；海外方面，美国计划对铜进口展开调查，未 来或对铜进口征收新的关税，此举或导致我国铜产品抢出口的行为。

钼（Molybdenum，化学符号Mo）是1778 年由瑞典化学家C.W Scheele 首先从辉钼矿（MoS2）中提炼出来的一种金属元素。 位于元素周期表第五周期第6族（铬分族），为过渡金属元素。 Ø 钼金属具银白色金属光泽，具备高强度、高熔点、高硬度、 导热导电性能好、耐研磨、热膨胀系数小、抗腐蚀性能强等 优良特性，不可替代性强。

Copper wire is a type of electrical conductor made from copper metal and is widely used in electrical wiring in various industrial applications, such as building and construction, power generation, telecommunication, and transportation. The copper wires offer superior electrical transmission with hardly any resistance and require less insulation. Copper wires are widely used in creating copper cables, where multiple copper wires are assembled into a standard jacket.

Metal stampings are components produced by placing flat sheets of metal into a stamping press. It is an intricate procedure that may involve several metal-forming methods, such as punching, bending, piercing, and blanking. Metal stamping parts are mainly used for supporting other parts of products or as function parts. They are also used as enclosures to cover the products.

Metal machining can be defined as a manufacturing process in which cutting tools are used to remove unwanted metals from metal workpieces and convert them into the shape required. Metal machining includes various machining processes such as turning, milling, drilling, and grinding, which are used to shape and finish metal workpieces to meet specific requirements and specifications.

Iron castings refer to objects or components that are produced by pouring molten iron into a mold and allowing it to solidify and take the shape of the mold.
