从成分构成来看，S 型铂铑丝的电极设计遵循 "正极含铑 10%、含铂 90%，负极为纯铂" 的标准。这一配比使其在中温测量场景中具备稳定的热电性能，广 泛应用于玻璃制造、陶瓷烧结等工业环节。而 B 型铂铑丝的成分设计则更为复杂：正极含铑量提升至 30%、含铂 70%，负极采用铂铑合金（含铑 6%）。这 种高铑含量的配方，让 B 型铂铑丝在 1600℃以上的超高温环境中仍能保持优异的抗氧化性与热电稳定性，是航空航天、冶金等高端工业领域的核心材料。 铑作为一种稀缺贵金属，当前市场单克价值约 1500 元，其价格远超铂（约 200-300 元 / 克）。B 型铂铑丝的总铑含量（正极 30%+ 负极 6%）显著高于 S 型 （仅正极 10%），这直接导致其原材料成本大幅上升。此外，B 型铂铑丝的生产工艺要求更高，需精准控制高比例铑的均匀分布，进一步推高了其市场价 格。 根据今日最新回收行情，S 型铂铑丝回收价为 330 元 / 克，B 型铂铑丝则达到 453 元 / 克，价差与成分差异形成明确对应。这种价格差异不仅反映了材料本 身的价值，更体现了不同型号铂铑丝在工业应用中的性能层级 ——B 型以更高的铑含量换取了更极 ...

Group 1 - The price of platinum-rhodium wire has recently surpassed 406 yuan per gram, marking a 12% increase from 360 yuan over the past three months [1][3] - The demand for platinum-rhodium alloys is driven by their essential role in automotive catalytic converters and the glass fiber industry, with increased usage due to stricter emissions standards for fuel vehicles [3][5] - The global supply of rhodium is heavily concentrated in South Africa, where power crises have led to the shutdown of several smelting plants, tightening the supply chain and driving prices up [3][5] Group 2 - The current price of 406 yuan per gram is 35% higher than the same period in 2023, with downstream glass manufacturers just beginning to adjust their purchase prices [5] - Technical analysis indicates that the price is nearing the upper Bollinger Band, suggesting potential volatility ahead [5] - A strategy of selling in three batches is recommended, with the first batch being 30% of the total volume to secure initial profits, while the remaining 70% should be monitored for further price movements [7]
