1. What is the brass forging process?
The brass forging process is a process of applying pressure to the brass blank by using a brass forging machine to cause plastic deformation to obtain a brass forging product with certain mechanical properties, a certain shape and size.

Forging is one of the two major components of forging (forging and stamping). Forging can eliminate defects such as as-cast looseness during brass smelting and optimize the microstructure. At the same time, due to the preservation of the complete brass streamline, the mechanical properties of forged brass are generally better than castings of the same material.

The original state of brass forging process materials includes bar stock, ingot, brass powder and liquid brass. The ratio of the cross-sectional area of brass before deformation to the cross-sectional area after deformation is called the forging ratio. Correct selection of forging ratio, reasonable heating temperature and holding time, reasonable initial forging temperature and final forging temperature, and reasonable deformation amount and deformation speed, are greatly related to improve the quality of forged brass forgings and reduce the cost.

The general small and medium-sized brass forging process uses round or square bars as blanks. The grain structure and mechanical properties of the bar are uniform and good, the shape and size are accurate, and the surface quality is good, which is convenient for mass production. As long as the heating temperature and deformation conditions are reasonably controlled, forged brass with excellent properties can be forged without large forging deformation.

2. Defects that are easy to occur in the process of brass forging process
Overheating, overburning; forging cracks; cutting edges torn; when the folded copper alloy is deformed, the surface is easy to wrinkle, causing folding accordingly; coarse grains; stress corrosion cracking.
