hot / cold rolled crystalline structure
hot / cold rolled crystalline structure
(OP)
Which has the largest crystal structure between hot or cold rolled metals, especially Brass and Aluminium, and why?
Also, which of the two is used most for stamping parts from?
I work for a manufacturer of abrasives, one of which is a polishing product which, on some non-ferrous stampings, appears to drag the surface creating occasional teardrop shaped pits. This we can only put down to the crystal structure of the surface but, as end-users rarely know what they are working with, we need to know whether hot or cold rolled is to blame so we can offer the best recommendations to customers.
Thanks for the help.

RE: hot / cold rolled crystalline structure
Both are used quite often for stamping parts.
Abrasive embedment and metal surface damage are functions of metal strength, hardness and stiffness, abrasive stiffness and hardness, presence or absence of lubrication, and pressure applied to the surface.

Your post above needs to be edited - cold rolled metals are typically harder in comparison to hot rolled metals. Cold rolling, which is performed below the recrystallization temperature of the metal, typically results in a phenomenon called "work hardening" that increases the hardness of the metal.

Thank you! I write too faster sometimes...
Make post "Cold-rolled is typically harder than hot-rolled..."
