CMC Alloy – Provided By Chinatungsten Online
Hey, it is sunny day, all the same.
Well, the good weather makes us feel much more comfortable and full of passion. Today, let us have a short profile about CMC.
CMC alloy, from the words, you must know that it is the short name of something. Yeah, that right, its full name is copper molybdenum copper alloy, also named Cu-Mo-Cu alloy. CMC alloy is a kind of multiple composite alloy; it is just like a hamburger which has three-tier structures, the Cu lays in the button, the middle one is Mo and the first is Cu. It uses pure molybdenum as the core material, and then covered with copper on the double sides.
The thermal expansion coefficient of CMC alloy is adjustable while has high thermal conductivity and high temperature performance. The regular production is rolling complex, composite plating, explosive forming etc. Maybe, now you are thinking about what it is used for? Well it is usually used as a heat sink and the channel between lead frame and multilayer printed circuit board (PCB) which is used as thermal and expansion part. That sounds really cool.
