Cemented carbide steel and alloy die steel can both be used to make dies, but what are the advantages and disadvantages of each? What is a better alloy for extrusion dies used at about 400 degrees, and what is a better steel for cold drawing? It is mainly aluminum alloy processing. In addition, what is better for the corresponding lubricant!
I this kind of aluminum alloy processing mainly has two points: 1, hot extrusion, extrusion temperature about 350-400 degrees or so, extrusion into the diameter of about 10 or so wire, here the main requirement of wire surface quality as high as possible.
2, cold drawing process, there are two important aspects: a, the cold drawing process of the die and lubricants, the focus is to do their best to ensure or even improve the surface quality, especially the finish and brightness; b, if 1-2 times stretching can not reach the size of the processing wire, we must go through the intermediate annealing, intermediate annealing is generally between 300-450 degrees, after annealing Continue stretching. After repeated annealing stretching finally processed into finished products.
