Making forged brass is a longer, superior process than stamped or cast brass. Once the brass is molten, it is poured into a mold. This process is very similar to pouring heated, liquid into a mold, and waiting for it to cool. Normally, cast products are hollow and not as durable. The forging process can create parts that are stronger than those manufactured by other metalworking process. Therefore, forging is almost always used where reliability and human safety are critical.
