Is Cu-Zn alloy a memory alloy? . Golden yellow, like gold, commonly known as brass.
There are dozens of components in Cu-Zn memory alloy. Usually, the main components of Cu-Zn memory alloy that we can use are: Cu 64% Zn 18% Ni 18% or Cu-Zn-Al memory alloy. Martensite transformation temperature is about 65438 000℃.
Ordinary brass is a binary alloy of copper and zinc, and the content of zinc is very different, so its room temperature structure is also very different. According to the binary state diagram of copper and zinc, there are three kinds of room temperature microstructures of brass: brass with zinc content below 35%, and the room temperature microstructure is composed of single-phase α solid solution, which is called α brass.
The microstructure of brass with zinc content ranging from 36% to 46% is composed of (α+β) two phases at room temperature, which is called (α+β) brass (biphasic brass). The microstructure of brass containing more than 46% ~ 50% zinc is only composed of β phase at room temperature, which is called β brass.
