al5052铝合金的硬度
根据铝板带国家统一标准《GB/T3880-2006》
国标5052铝板硬度根据交火状态(即热处理工艺)不同,布氏硬度从46HB到77HB不等,详见下图:
有疑问请追问,希望帮到你。
铝板al5052h32和h34的区别
一、抗拉强度不一样:H32的抗拉强度是210-260 ;H34的抗拉强度是230-280。抗拉强度(tensile strength)是金属由均匀塑性变形向局部集中塑性变形过渡的临界值,也是金属在静拉伸条件下的更大承载能力。
二、规定非比例延伸强度不一样:H32规定的非比例延伸强度是130 ;H34规定的非比例延伸强度是150 。规定非比例延伸强度Rp的定义是非比例延伸率等于规定的引伸计标距百分率时的应力,Rp0.2即为规定的引伸计标距0.2%时的应力。
三、弯曲半径不一样:H32的弯曲半径是1.5t;H34的弯曲半径是2.0t。弯曲半径是曲率半径。通俗地说,是把曲线上一个极小的段用一段圆弧代替。这个圆的半径即为弯曲半径。
扩展资料
一、GB/T 3880的本部分规定了一般工业用铝及铝合金板、带材的力学性能,本部分适用于一般工业用铝及铝合金轧制板、带材。板、带材的室温拉伸试验结果、弯曲性能试验执行的弯曲半径等应符合该标准。
二、抗拉强度即表征材料更大均匀塑性变形的抗力,拉伸试样在承受更大拉应力之前,变形是均匀一致的,但超出之后,金属开始出现缩颈现象,即产生集中变形;对于没有(或很小)均匀塑性变形的脆性材料,它反映了材料的断裂抗力。符号为Rm(GB/T 228-1987旧国标规定抗拉强度符号为σb),单位为MPa。

AL6063-T5和AL5052-H32有什么区别?
1、主要材料不同:
AL6063-T5的主要合金元素为镁与硅,AL5052-H32的主要合金元素只有镁。
2、用处不同:
AL6063-T5是广泛应用于建筑型材、浇灌管材、供车辆、台架、家具、升降机、栅栏等用的管、棒、型材。
AL5052-H32是用于制造飞机油箱、油管、以及交通车辆、船舶的钣金件,仪表、街灯支架与铆钉、五金制品、电-器外壳等。
扩展资料:
AL6063-T5具有诸多可贵特点:
1、热处理强化,冲击韧性高,对缺口不敏感。
2、有很好的热塑性,可以高速挤压成结构复杂、薄壁、中空的各种型材,或锻造成结构复杂的锻件。淬火温度范围宽,淬火敏感性低,挤压和锻造脱模后,只要温度高于淬火温度,即可用喷水或穿水的 *** 淬火。薄壁件(δ3mm)还可以实行风淬。
3、焊接性能和耐蚀性优良,无应力腐蚀开裂倾向,在热处理可强化型铝合金中,Al-Mg-Si系合金是唯一没有发现应力腐蚀开裂现象的合金。
4、加工后表面十分光洁,且容易阳极氧化和着色。其缺点是淬火后,若在室温停放一段时间,在时效上会对强度带来不利影响(停放效应)。
