(brass tube 1-1 4 o.d)Human use of copper can be traced back to the earliest1ten thousand years ago,Archaeologists have excavated in northern Iraq1Copper beads made of natural copper thousands of years ago。The history of using copper in my country can also be traced back to4000years ago,However, the earliest people used directly smelted copper to make objects,found too soft,Service life is too short。Later, people joined some other metals in it.,copper alloy formed,The performance of copper has been greatly improved。now,According to the alloy composition,can be divided into brass、copper、Tin bronze、white copper,So what's the difference between them?

copper

Copper is the type of copper with the highest copper content,copper content reached99.5%arrive99.95%,Other elements are some impurities。Therefore, it can also be called pure copper。From the appearance,Copper Zeng Rose Red,The color is purple after oxidation。The grades of pure copper are generally composed ofT+Sequence number(Sequence numbers mean that as the copper content decreases with increasing sequence numbers),E.gT1、T3Wait;another exampleTP2、TAg0.1etc. is also pure copper,Oxygen-free copper is usedTU1、TU2etc. to express。in terms of performance,Copper has good plasticity and good electrical and thermal conductivity,Therefore, it is often used in cables、wire etc.。

brass

Brass is an alloy of copper and zinc,The most common elements are copper and zinc。But in actual use,Often there are other elements,as lead、manganese、Nickel etc.,To increase the hardness of brass、strength and chemical resistance。From the appearance,Brass is yellow。The grades of brass are generallyH+Copper content(percentage),E.gH59、H90Wait。More complex brass will be usedH+chemical symbol of the second element+Content of elements other than zinc(use-separated),E.gHPb89-2Wait。in terms of performance,Brass has better wear resistance,in some valves、Commonly used in pipelines,soft、Strong wear resistance。some shells、Musical instruments, etc. are also made of brass。

bronze

Bronze is the earliest bronze alloy used,The earliest alloy of copper and tin,tin bronze。But later for the convenience of management,copper and zinc、Copper alloys other than nickel are called bronze。lead bronze、Aluminum bronze etc.。From the appearance,Bronze blue。In terms of grades, the marking method in my country is as follows:Q+chemical symbol of first main additive element+Content of elements other than zinc,E.g:Q Al5Wait。However, there are also some commonly used cast copper alloy grades.:5-5-5Tin bronze(ZCuSnPb5Zn5),10-3aluminum bronze(ZCuAl0Fe3)Wait。The casting properties of tin bronze are very good,Has minimal shrinkage,So great for casting some turbines 、gear etc.。

white copper

Cupronickel is an alloy of copper and nickel。From the appearance,white copper silver。The grades of white copper are expressed as follows:

There are two types of cupronickel: structural cupronickel and electrical cupronickel.。Structural cupronickel corrosion resistance number,Such asB30、B10Wait。Commonly used in instrumentation and medical devices。Electrical cupronickel has good thermoelectric properties,Such asBMn3-12Wait,Common Terms Resistive Elements。

in terms of price,The most expensive copper,second place copper,followed by bronze,The cheapest is brass。But the cheapest one is several times more expensive than iron.。
