简介
播报编辑7075铝板7075指的是7系铝合金中的一种常用的合金，比较常见的铝合金中强度最好的就是7075合金，普遍用在CNC切削制造的零部件，适合飞机构架及高强度配件。7系铝合金包含有锌和镁元素。锌在这系列中是主要合金元素，所以抗腐蚀性相当好，加上少许镁合金可使材料能受热处理后达到非常高的强度。7系铝合金属Al-Zn-Mg-Cu系超硬铝，该合金是20世纪40年代末期就已应用于飞机制造业，仍在航空工业上得到广泛应用的超高强度变形铝合金。其特点是，固溶处理后塑性好，热处理强化效果特别好，在150℃以下有高的强度，并且有特别好的低温强度；焊接性能差；有应力腐蚀开裂倾向；需经包铝或其他保护处理使用。双级时效可提高合金抗应力腐蚀开裂的能力。在退火和刚淬火状态下的塑性稍低于同样状态的2A12.稍优于7A04，板材的静疲劳.缺口敏感，应力腐蚀性能优于7A04.密度为2.85g/cm3。

播报编辑航空固定装置，卡车，塔式建筑，船，管道及其他需要有强度的建筑上的应用的领域。如：飞机零部件、齿轮和轴、熔丝零件、仪表轴和齿轮、导弹零件跳进阀零件、涡轮、钥匙、飞机、航空及国防应用。
状态代号
播报编辑范围本标准规定了变形铝合金的状态代号。本标准适用于铝及铝加工产品。基本原则2.1基础状态代号用一个英文大写字母表示。 　2.2细分状态代号采用基础状态代号后跟一位或多位阿拉伯数字表示。 　2.3基本状态代号 　基本状态分为5种 　代号 名称 说明与应用 　F 自由加工状态 适用于在成型过程中，对于加工硬化和热处理条件无特殊要求的产品，该状态产品的力学性能不作规定。 　O 退火状态 适用于经完全退火获得最低强度的加工产品。 　H 加工硬化状态 适用于通过加工硬化提高强度的产品，产品在加工硬化后可经过（也可不经过）使强度有所降低的附加热处理。 　W 固熔热处理状态 处理状态 一种不稳定状态，仅适用于经固溶热处理后，室温下自然时效的合金，该状态代号仅表示产品处于自然时效阶段。 　T 热处理状态(不同于F、O、H状态) 适用于热处理后，经过（或不经过）加工硬化达到稳定的产品。T代号后面必须跟有一位或多位阿拉伯数字。在T字后面的第一位数字表示热处理基本类型（从1~10），其后各位数字表示在热处理细节方面有所变化。如 6061—T 62 ；5083—H 343等。 　T1—从成型温度冷却并自然时效至大体稳定状态。 　T2—退火状态（只用于铸件）。 　T3—固溶处理冷作后自然时效。 　T31—固溶处理冷作（1%）后自然时效。 　T36—固溶处理冷作（6%）后自然时效。 　T37—固溶处理冷作（7%）后自然时效，用于2219合金。 　T4—固溶处理后自然时效。 　T41—固溶处理后沸水淬火。 　T411—固溶处理后空冷至室温，硬度在O及T6之间，残余应力低。 　T42—固溶处理后自然时效。由用户进行处理，适于2024合金，强度比T4稍低。 　T5—从成型温度冷却后人工时效。 　T6—固溶处理后人工时效。 　T61—T41+人工时效。 　T611—固溶处理，沸水淬火。 　T62—固溶处理后人工时效。 　T7—固溶处理后稳定化。提高尺寸稳定性，减小残余应力，提高抗蚀性。 　T72—固溶处理后过时效。 　T73—固溶处理后进行分级时效，强度比T6低，抗蚀性显著提高。 　T76—固溶处理后进行分级时效。 　T8—固溶处理冷作后人工时效。 　T81—固溶处理后冷作，人工时效。为改善固溶处理后的变形及改善强度。 　T86—固溶处理后冷作（6%），人工时效。 　T87—T37+人工时效。 　T9—固溶处理后人工时效再冷作。 　T10—从成型温度冷却，人工时效后冷作。 　Tx51—为消除固溶处理后的残余应力进行拉伸处理。 　板材0.5~3%的永久变形，棒、型材1~3%的永久变形。 　X代表3、4、6或8，例如T351、T451、T651、T851，适用于板、拉制棒、线材，拉伸消除应力后不作任何矫正而时效。T3510、T4510、T8510，适用于挤压型材，拉伸消除应力后为使平直度符合公差进行矫正，并时效。 　Tx52—为消除固溶处理后的残余应力进行压缩变形，固溶处理后进行2.5%的塑性变形然后时效，例如T352、T652。 　Tx53—消除热应力。 　Tx54—为消除精密锻件固溶处理后的残余应力进行压缩变形。

JFE钢铁 从20世纪50年代后半期初开始率先生产和销售耐磨钢板，作为重要材料被广泛应用在工程机械、矿山 机械、农业机械上。 而且，JFE钢铁在成功开发出耐磨性超过布氏硬度500级别的超级耐磨钢“EH-SP”之后，利用最先进的 工艺又成功开发出了具有优良低温韧性的EH360LE，EH500LE，得到了用户的好评。 在此介绍的是JFE钢铁的耐磨钢板“JFE-EH”，敬请广大用户继续给以照顾。 JFE EVERHARD的特点品种多样包括按硬度级别归类的2大系列(标准系列3种和合金系列2种)、以及超级耐磨钢、高韧性耐磨钢，共计8种，可以满足各种用途的需要。标准系列该型号炼钢时减少了添加的元素，且是添加硼(B)的单纯成分系列，是重点追求钢板硬度的产品。合金系列该型号与标准系列相比，增加了合金元素的添加量、在厚度为100毫米以内时能够保证达到规定的硬度。同时也考虑了低温条件下的韧性。超耐磨钢(EH-SP)从降低运行成本费用方面考虑，通常要求提高耐磨钢的寿命。但是，从焊接性、加工性方面来考虑，采用已往的方法则难于制造耐磨性超出布氏硬度500级别的钢材。JFE钢铁开发的“EH-SP”，不但没有降低焊接性、加工性，而且具有比已往布氏硬度500级别更高的耐磨性。高韧性耐磨钢(EH360LE、EH500LE)JFE钢铁利用最先进的工艺，开发出了可保证在-40℃低温下硬度达到500的最高级别韧性的耐磨钢，这是至今为止难以做到的。尤其是在寒冷地区使用、受到强烈冲击时等场合，需要高韧性的场合，此产品最为适合。另外，因为同时具备了高耐焊接开裂性能，可放心使用。质量优异JFE钢铁的耐磨钢板是在最新式的钢铁厂，经过数十年生产经验的积累，采用最新的热处理技术，在高度质量管理下制造而成的。其耐磨性能自不必说，在焊接性和加工性方面也进行了精心考虑,保证具备优异的质量。JFE EVERHARD的规格JFE钢铁的耐磨钢是保证了如下所示的化学成分(钢包内取样分析)、和钢板表面的布氏硬度以及韧性的非结构钢板，所以，对用于结构用途时所需的拉伸强度、延伸率恕不予保证。若需要拉伸强度、延伸率的参考值，请参照技术资料。1 化学成分 *根据需要，有时会添加上述表格以外的元素。此处所列的化学成分全部来自对钢水的化学分析。**　Ceq = C + Mn / 6 + (Cu + Ni) /
