metal or plastic material properties spec 去 www.matweb.com 看看吧! |

大哥,好久没见!
都是酱的咯,但是我告诉你哦,有时候他们(supplier)竟然直接将Matweb 的material spec印出来。
简直就是骗人 |

请问下material spec cert 和 report 有什么分别?
我那是只是去询问价钱和买少少东西,没有大量购买所以并没有和他们讨下去。
他们只有给material spec cert而且呢~~~和matweb 的一抹一样的。
我是说aluminium.
你熟悉aluminium 吗?特别是 Al7075,2024,6061. |

这些对我来说是没用的。
我要的是那批货是我要的材料。
我们担心货不对版。
现在,我们有的问题是6061的extrusion property。
ASM,MIL这些权威性是派不上场的,因为不是用来做case study。
如果是plate, block就还好因为是进口,肯定有 material spec.
只是本地extruded 过后的property.
本地其中一间很大aluminium 厂 (Kxxxx)就是一样,给我们看的spec完全和 matweb 一样。
那里可能呢。
请问下material spec cert 和 report 有什么分别?
对了,还有一样想问你,你熟悉aluminium 吗?(不是它的material property)你知道本地有哪间厂有2024-T4/T351 sheet (thickness=1.0mm, 1.6mm, 1.8mm, 2.0mm) 吗?
谢谢
