Will the brass rod resist corrosion when aluminum is added

What are the properties of brass rods?  For this question, many friends who have come into contact with this material for the first time do not know how to answer it.  Below, the author on this aspect of knowledge, simple to share with you.  

Brass rod is actually an alloy of copper and zinc element, speak a little bit more simple, is that it is made up by copper and zinc, which has simple brass or ordinary brass, of course, the zinc content and the corresponding change of brass, you can get different mechanical properties of brass, the need of special note is the higher zinc content of brass,  Its strength will be higher, the shape is slightly lower.  

The zinc content of brass rod used in the industry will not exceed 45%, zinc content again high, it will directly affect the brittleness, and then make the performance of the alloy deteriorated, in order to improve some performance of brass, on the basis of one brass, add other alloy elements of brass, is called special brass,  For example, common alloying elements are aluminum, tin, lead, manganese, silicon and so on.  

About the personage inside course of study says, after joining aluminium this element of brass rod, can improve product yield strength and corrosion resistance, of course, this sort of shape there will be a little lower, less than 4% of lead brass products has good comprehensive properties such as machining, casting, adding 1% tin element in the brass,  It can significantly improve the resistance of brass to sea water and atmospheric corrosion, so it is also known as "naval brass".  

To note is the tin can also improve the machinability of brass rod, brass leaded the main purpose is to improve the cutting machining and improving wear resistance, lead to the strength of the brass, manganese brass has good mechanical properties, thermal stability and corrosion resistance, lead to join in the middle of the manganese brass, also can improve its performance, smooth surface castings.
