Analysis of brass rod hardness: from the perspectives of composition, processing and usage scenarios
1. The influence of composition on the hardness of brass rods
The main components of brass rods are copper and zinc, generally the copper content is between 60% and 90%, and the zinc content is between 10% and 40%. Different components will lead to differences in the hardness of brass rods. Generally speaking, the higher the copper content, the lower the hardness of the brass rod, and the higher the zinc content, the higher the hardness of the brass rod.
2. The effect of treatment on the hardness of brass rods
The treatment method of brass rods will also affect their hardness. Common treatment methods include annealing and cold working. Annealing refers to heating the brass rod to a certain temperature and then slowly cooling it. This treatment method will reduce the stress inside the brass rod and reduce its hardness. Cold working refers to stretching, compressing or rolling the brass rod, at which time the hardness of the brass rod will increase.
