Brass fitting made in china there is a material called complex brass

　　Brass complex also brass fitting made in china in one. Why does it have to be called complex brass it Because the manufacturers in order to improve the performance of some of the brass. In some special occasions, the required properties of brass are different.

　　Some situations require high strength brass, some occasions require high hardness brass, some situations require good corrosion resistance of brass. Therefore, it will add a small amount of tin in brass, aluminum, manganese, iron, silicon, nickel, lead elements constitute or three or four or even five-alloy, this brass brass is complex, it can also be called special brass.

　　In the copper-zinc alloy, adding small amounts of other alloying elements, usually just let α / (α β) phase region to the left or right. Because of special brass phase α phase and β is a diverse and complex solid solution strengthening effect of it for very large brass. Therefore, a small amount of brass alloy elements in the alloy to improve the properties of a good way. Adding other alloying elements in brass, such as the addition of lead brass, will increase its plasticity. Join the tin brass, its heat resistance can be improved.

　　Complex brass is brass fitting made in china in a technically and have a good performance breakthroughs. This can make brass fitting made in china have more useful.
