The difference between extrusion and drawing of aluminium bars
The annealed (copper rod is not annealed) is much better than the extruded aluminum rod. The extrusion rod is small in use, but the drawing rod made by extrusion and drawing is much better and has a wide range of uses. The latter is the latter.
The performance of the extruded bar is worse than that of the drawn bar, and the microstructure and properties of the extruded rod are not uniform.
Extruded aluminum rod is extruded ingot heating, drawing aluminum rod has two ways: one is the aluminum rod extrusion after cold deformation, supplemented by annealing process of the formation of the development of products; two is the ingot (usually horizontal ingot) directly peeling and tensile deformation formation product.
