产品描述
上海顶点合金有限公司（Shanghai Vertex Alloy Co., Ltd，简称 Vertex Alloy）供应 Monel 蒙乃尔合金 404（UNS N04404）带材、线材、圆棒及棒材，执行 ASTM F96-77（2015 重新批准）标准。F96 表 1 将其命名为 Alloy 4（55Ni-45Cu），是电子级铜镍合金加工形态标准。N04404 化学成分 Ni 52–57%，Cu 余量，Fe/Mn/Si/Al 均严格限值（≤0.5/0.1/0.1/0.05%），从而实现磁导率 μ ≈ 1.0017（接近真空）、居里温度 ≤ -100°C（远低于室温）、电阻率 0.494 µΩ·m。高 Cu 含量带来优异钎焊性和陶瓷-金属封接性——是晶体管外壳、陶瓷-金属封接件、电子管、继电器、MRI 兼容部件的标准材料。单相固溶体，不能通过热处理硬化，强度由冷加工获得（最大约 850 MPa 抗拉）。带材厚度 0.05–3 mm，箔材低至 0.01 mm 可定制，线材 Ø 0.1–8 mm，圆棒 Ø 6–100 mm；退火态含 F96 第 8 节规定的深冲晶粒度控制。EN 10204 3.1 材质证明。MONEL® 为 Special Metals Corporation 注册商标
