How to affect its effect of performance of the brass fitting made in china

　　Brass fitting made in china has its presence in many countries, it has so much usefulness. People have used it think it is very good. Due to technical progress of brass fitting made in china, also make it better. Brass fitting made in china widely used because of its properties.

　　Performance brass brass can have a lot of roles: the first one is the brass has a good plasticity. α phase brass to withstand cold single processing step of forging it can withstand the heat range is different according to the amount of Zn -containing varies . Brass generally between 200 ~ 700 ℃. Because there are two β -phase brass , and brass in a high temperature causes a high plasticity, less than at lower temperatures .

　　The second is the brass can be warm. Brass is an alloy of copper and zinc binary general , changes in the scope of its zinc content is relatively large, so room temperature is very different organizations . The third mechanical properties . α brass, with the increase in zinc content , σb and δ are constantly increased. (Α + β) brass, when the zinc content increased to about 45% , room temperature strength continues to increase. If it then increases the amount of zinc , it will drastically reduce its strength. So, more than 45% of the zinc -zinc alloy no practical value.

　　These are the brass fitting made in china introduced performance , its role is to some factors as it changes .
