The classification of copper alloys is finished,Let's talk about the development trend of copper alloys:

1、Highly purified:The main purpose of high purification is to improve the conductivity of the material as much as possible、thermal conductivity。The copper content of industrial copper is determined by99.90%arrive99.95%,again99.99%(4N)even higher,as copper99.9999%(6N)of ultrapure copper,Impurity content requirements are also more stringent。as oxygen(O)amount by0.01%~0.05%decrease to0.001%~0.006%,until0.0002%~0.0003%。Minimize impurities on conduction、The effect of thermal conductivity。Typical application examples are high-purity copper for network transmission connection wires、High-purity oxygen-free copper for electric vacuum devices、Precision guidance and high-fidelity signal transmission and single crystal copper and ultra-pure copper for superconductors, etc.。

compared to polycrystalline copper,The tensile strength of single crystal copper is reduced24.71%,Elongation increased2.39times,Area shrinkage increased4.14times,The resistivity is reduced31.7%,less than1.72×10-8Ω·m,Its oxygen content is less than5×10-6,The hydrogen content is less than0。。。5×10-6,density greater than8.92t/m3.

(albion alloys 12 x 1 16 square brass tube)Another aspect of the development of copper alloy materials in the direction of high purification is that in microalloyed copper alloys, high purification of the copper alloy matrix is required.,,In order to ensure that the material has a higher comprehensive performance。

2、microalloying:The purpose of microalloying is to sacrifice minimal electrical and thermal conductivity for other properties,such as a substantial increase in strength。if join0.1%left and right iron(Fe)、magnesium(Mg)、tellurium(Te)、silicon(Si))、silver(Ag)、titanium(Ti)、chromium(Cr)or pickaxe(Zr)、rare earth elements, etc.,can increase its strength、hardness、Resistance to softening temperature or machinability, etc.。Micro-alloyed copper is one of the hot spots in the development of copper alloy materials。Oxygen tough copper and high-strength and high-conductivity copper alloys are the most important microalloyed coppers。

The concept of oxygenated copper is relative to oxygen-free copper,Its copper content is99.90%above,Equivalent to ordinary pure copper,But its oxygen content is controlled at0.005%~0.02%,At the same time, the electrical conductivity can be100%IACSabove。This is because an appropriate amount of oxygen has a certain oxidative effect on the intergranular impurity elements.,Cleans the substrate to a certain extent。The biggest feature of aerobic copper production is the low cost of its raw materials,The use of low-grade red copper old materials to produce oxygenated copper materials equivalent to high electrical and thermal conductivity。

(albion alloys 12 x 1 16 square brass tube)High strength and high conductivity copper alloy due to its good comprehensive properties,Favored by material science and technology workers from all over the world,It is the fastest growing class of copper alloys in recent years。The elements added to its microalloying are mainly::P、Fe、Cr、Zr、Ni、Si、Ag、Sn、AlWait,The representative alloy systems are mainlyCu-P、Cu-Fe-PTie、Cu-Ni-SiTie、Cu-Cr、Cu-Cr-ZrTie、Cu-Ag、Cu-Ag–Cr、Cu-Ag-ZrTie、Cu-SnDepartment, etc.,and various rare earth-added alloy systems。The sum of the contents of other components in the alloy can be at least0.01%~0.1%,The maximum generally does not exceed3%。Its common feature is that the material has high strength and high conductivity.。

3、Complex multi-alloying:To further improve the strength of copper and its alloys、Corrosion resistance、Wear resistance and other properties,Or in order to meet some special application requirements,in existing bronze、Brass, etc. are added to the five yuan on the basis of、Six yuan and other components,Realize high elasticity of materials、High wear resistance、High corrosion resistance、Easy cutting and other different functions,multicomponent(four or more components)Alloying becomes another hot topic in copper alloy development,New complex alloys are emerging。Typical alloys are multicomponent manganese brass、Silicon manganese brass、Boron Tin Brass、Lead-free free-cutting copper alloys, etc.。Its common feature is high strength and high toughness,The tensile strength is generally up to600~700MPaabove。E.g,New manganese brassHMn59-2-1-0.5(Cu:58%~59%、Mn:1.8%~2.2%、Al:1.4%~1.7%、Fe:0.36%~0.65%、Si:0.6%~0.9%、Sn:0.1%~0.4%、Pb:0.3%~0.6%、Znmargin),The strength of its control tube reaches600MPaabove,Elongation exceeds20%,hardnessHBexist180above。aluminum brassHAl64-5-4-2(Cu:63.5%~65.5%、Al:4.5%~6.0%、Mn:3.0%~5.0%、Fe:2.0%~3.0%、Pb:0.2%~1.0%、Znmargin),its strength reaches750MPaabove,hardnessHBExceed220。New aluminum bronzeQAl9-5-1-1(Cu:margin、Al:8.0%~10.0%、Ni:4.0%~6.0%、Mn:0.5%~1.5%、Fe:0.5%~1.5%),Its strength is650MPa,Yield strength up to400MPa,Elongation up to14%above。Application of these materials to manufacture automobile synchronizer ring gear、High pressure pump friction pair or electrode copper wedge,Its life is one to several times longer than that of ordinary brass or bronze。

In recent years,With the increasing awareness of environmental protection,Environmental protection has become the theme of the development of world civilization。People pay more attention to lead、beryllium、cadmium、Effects of harmful elements such as arsenic,Lead Free Free Cutting Brass、Beryllium-free highly elastic copper alloy、The development of environmentally friendly copper alloy materials such as arsenic-free corrosion-resistant copper alloys has become one of the important development directions of copper alloy materials.。

4、composite material:There are two main ways of copper alloy material:One is to introduce alloying elements to strengthen the copper matrix to form an alloy;The second is to introduce the second strengthening phase to form composite materials。For example, dispersion-strengthened oxygen-free copper is a typical artificial composite material.,Commonly used disperse particles areAl2O3、ZrO2、Y2O3、ThO2Wait。The artificial composite method refers to the artificial addition of particles of the second phase to the copper、Whiskers or fibers reinforce the copper matrix,By introducing uniformly distributed、Fine、Materials prepared by strengthening copper with good thermally stable oxide particles。The composition of the second phase is generally in1%below or even lower to0.01%,However, the strengthening effect on the material is very obvious,In particular, the high temperature strength of the material is greatly improved。Such asCu-2.5%TiB2(Volume fraction),Conductivity is76%LACS,The tensile strength is675MPa;Cu-0.5%Al2O3(Quality Score)Series alloys,The greenhouse strength of the material can reach500~800MPa,conductivity up to85%LACSabove,exist900℃The strength of the material after burning hydrogen still reaches200~400MPa.

(albion alloys 12 x 1 16 square brass tube)Another type of rapid development is in situ composite materials(self-contained material),In situ composites are those in a copper matrix,A class of composite materials that generate a reinforcing body through an element or an element and a compound of the compound。这类复合材料中的增强体没有界面污染,The reinforcing body in such composite materials does not interface pollution,与传统的人工外加增强体复合材料相比,Have good interface compatibility with the substrate,同时保持较好的韧性和良好的高温性能。Compared to traditional artificial plus enhancement compositesCu-20%Nb(体积分数)Its intensity has a large increase,接近2000Pa;Cu-18%(Maintain better toughness and good high temperature performance)的导电率为66.6%LACS,Such as1450MPa。其他如Cu-Fe、Cu-TaVolume fraction,材料的强度一般可达800~1500MPa.
