材料属性
播报编辑作为5XXX系列铝镁合金的典型代表，的化学成分包含硅（≤0.4%）、铁（≤0.4%）、镁（4.4-4.9%）等元素，铝含量占比超过95%。物理特性方面，其热膨胀系数为23.4μm/m·k（20-100℃），熔点范围570-640℃，电导率达到29%IACS（国际退火铜标准），电阻率0.059m㎡/m。
机械性能
播报编辑在力学性能指标上，该材料典型拉伸强度275-350MPa，屈服强度125MPa，延伸率12.5%（标距50mm）。硬度测试显示其布氏硬度值为65HB（500kg力10mm球），疲劳强度达到中等合金水平，能满足常规机械加工件的强度需求。
加工特性
播报编辑H112状态表明该材料通过热加工成型工艺实现加工硬化，未经后续热处理即能达到规定力学性能。其加工适应性包括：可进行冷加工成型（变形量不超过10%）适用氩弧焊、电阻焊等焊接工艺支持冲压、折弯等塑性加工 加工硬化程度由状态代号的第二位数字量化表征，H112对应特定的硬化等级指标。
应用领域
播报编辑2025年市场数据显示，该材料主要用于：船舶制造：船体外板、甲板支撑结构交通运输：轨道车辆底板、卡车车身框架工业设备：焊接压力容器、化工储罐建筑领域：海洋平台防腐蚀围护系统 典型应用案例包括预拉伸板制造（厚度3-30mm）、热轧厚板加工（极限厚度200mm）等 [1]。
产品标准
播报编辑该材料执行的主要标准包含：GB/T 3251-2006《铝及铝合金板材、带材》YS/T 495-2005《铝及铝合金热轧板材》ASTM B209《铝合金薄板和中厚板通用标准》 国内主要供应商如哈尔滨东方铝合金有限公司，生产规格涵盖3-30mm厚度范围，包含1250×2250mm及1500×4000mm等标准尺寸。
市场供应
播报编辑截至2025年6月，国内现货市场供应数据显示：常规厚度3-30mm板材单价约38元/kg最小采购批量20件起订（单件重18kg）主要供应商集中在长三角地区（上海、苏州） 国际流通产品包含美国铝业公司原材，通过台湾产加工设备完成二次成型。新手上路成长任务编辑入门编辑规则本人编辑我有疑问内容质疑在线客服官方贴吧意见反馈投诉建议举报不良信息未通过词条申诉投诉侵权信息封禁查询与解封©2025 Baidu 使用百度前必读 | 百科协议 | 隐私政策 | 百度百科合作平台 | 京ICP证030173号 京公网安备11000002000001号window.PAGE_DATA=
