Timeline:
01:05-03:55 正宗算力金属第一梯队:铟(磷化铟衬底)
1. 核心用途:光模块 EML 光源核心衬底,AI 算力刚需材料;全球原生铟年产仅千吨级,我国原生产量占 60%-70%。
2. 政策壁垒:2025 年 2 月磷化铟、金属源纳入出口管制,海外原料供给受限。
3. 供需缺口:全球衬底需求 200-300 万片,有效供给仅五六十万片,海外白板、外延工艺高度垄断,国内企业迎来国产替代窗口期。
4. 行业逻辑:上游资源国内高度把控,下游光模块需求持续爆发,是算力赛道核心卡脖子小金属。
03:55-08:00 正宗算力金属第二梯队:钨
1. 资源优势:全球原生钨 8 万吨 / 年,国内占 80%,开采配额管控,出口受限。
2. AI 两大核心需求:PCB 超细钻针、六氟化钨半导体靶材。
3. 需求增量:3-5 年 AI ...去小宇宙查看完整单集简介
