The main role of zinc in the brass rod
As we all know, the brass rod mainly is the metal zinc alloy material. However, what is the main role of zinc in the brass rod? Everyone to listen to me slowly:
1. Is able to enhance the mechanical strength and hardness of the brass rod, but not to reduce or reduce the copper processing plastic;
2. Have a beautiful color, can be used for different environment; At the same time has good adornment effect.
3. Hot and cold pressure processing performance is good, can be applied to the N kinds of processing methods, easy to get.
4. Save a lot of precious metals, and reduce material weight, the requirements and appropriate conductivity under the conditions of a certain intensity, the product price is low;
5. Zinc have degassing effect, after adding zinc in copper, zinc can not only by the volatile away a dissolved gas in the high temperature melt, and the ordinary brass for solidification temperature range is small and small segregation tendency, liquidity is good, not easy to form a dispersed pores etc, has higher ca-stability;
6. The addition of zinc make simple brass room temperature mechanical properties with the increase of the zinc content change: ordinary strength and hardness of the brass rod can be increased with the increase of zinc content increased, density, conductivity, thermal conductivity performance degradation, lower plasticity.
7. Change the re-crystallization temperature of brass rod. Cold, but at the same rate, the re-crystallization temperature of brass rod decreased with increasing the amount of zinc. Under the condition of production, often using 500-700 C anneal, such as shaft alpha grain can be obtained.
8. Influence of brass rod corrosion resistance.
