Copper alloys are alloys composed of one or several other elements added to pure copper.
The classification of copper alloy is still quite understandable. Copper alloys have a variety of colors, not copper copper alloy types, with different colors, copper alloys are mainly purple, yellow, cyan and other colors. When oxidized, copper alloy will also change color. Let's talk about the die casting process of copper alloy.
Copper alloys of different compositions of one or several other elements constitute the alloy, do you understand? For example, silicon brass, casting performance is better, the process is characterized by sequential solidification process, medium injection pouring system, dark riser size is small. There is also bronze and aluminum brass, their casting performance in terms of mobility, easy to form a concentrated shrinkage hole, very easy to oxidize.
We still immediately to explain the classification of copper alloy knowledge about it.
There are many ways to categorize copper alloys, and there are many types of copper alloys according to different methods. So let's talk about the classification of copper alloy:
1, brass: refers to copper and zinc based alloy, and can be subdivided into simple brass and complex brass, complex brass and the third group of yuan title for nickel brass, silicon brass, etc.;.
2, bronze: refers to in addition to copper-nickel, copper-zinc alloys other than copper-based alloys, the main varieties of tin bronze, aluminum bronze, special bronze (also known as high copper alloy);.
3, white copper: refers to the copper-nickel alloy.
4, copper: refers to pure copper, the main varieties of oxygen-free copper, copper, phosphorus deoxygenation copper, silver copper.
Copper alloy classification: according to the alloy system division
1, non-alloyed copper: non-alloyed copper, including high-purity copper, tough copper, deoxidized copper, oxygen-free copper, etc., customarily, people will be non-alloyed copper known as copper or pure copper, also known as red copper.
2, other copper alloys are alloy copper. Our country and Russia to alloy copper into brass, bronze and white copper, and then divided into small alloy system in the major categories.
Copper alloy classification: by function
1, electrical and thermal conductivity of copper alloys (mainly non-alloyed copper and micro-alloyed copper.
2, structural copper alloys: including almost all copper alloys.
3, corrosion-resistant copper alloys: mainly tin brass, aluminum brass, a variety of non-white copper, aluminum bronze, titanium bronze and so on.
4, wear-resistant copper alloys: mainly containing lead, tin, aluminum, manganese and other elements of complex brass, aluminum bronze and so on.
5,Free-machining copper alloy: copper-lead, copper-tellurium, copper-antimony and other alloys.
6, elastic copper alloy: mainly antimony bronze, aluminum bronze, beryllium bronze, titanium bronze, etc..
7,Damping copper alloy: high manganese copper alloy and so on.
8, art copper alloy: pure copper, simple single copper, tin bronze, aluminum bronze, white copper, etc..
Copper alloy classification: according to the material formation method is divided into
1, casting copper alloy: casting, and can be used for deformation processing.
2, deformed copper alloy: deformed copper alloy can be used for casting.
3, casting copper alloy and deformation of copper alloy can be subdivided into casting copper, brass, bronze and white copper.
