Copper industry knowledge: copper alloy classification
Copper alloy refers to an alloy composed of one or more other elements added to pure copper. The classification of copper alloys is quite easy to understand. There are many colors of copper alloys. The types of copper alloys without copper have different colors. The main colors of copper alloys are purple, yellow, cyan, etc.

The types of copper alloys without copper have different colors. The main colors of copper alloys are purple, yellow, cyan, etc. When oxidized, copper alloys will also change color. Let's talk about the die-casting process of copper alloys. Do you know about the alloys composed of one or more other elements of copper alloys with different compositions? For example, silicon brass has better casting performance. The process characteristics are sequential solidification process, center-injection pouring system, and small size of dark riser. There are also bronze and aluminum brass. They have better fluidity in casting performance, are easy to form concentrated shrinkage cavities, and are extremely easy to oxidize. Let's explain the relevant knowledge of copper alloy classification right away.
There are many ways to classify copper alloys, and there are many types according to different classification methods. Then let's talk about the classification of copper alloys:
Picture
From left to right, from top to bottom, they are: brass, bronze, white copper, and red copper
1. Brass: refers to an alloy based on copper and zinc, which can be further divided into simple brass and complex brass. Complex brass is named nickel brass, silicon brass, etc. with the third component;
2. Bronze: refers to copper-based alloys other than copper-nickel and copper-zinc alloys. The main varieties are tin bronze, aluminum bronze, and special bronze (also known as high-copper alloy);
3. White copper: refers to copper-nickel alloys;
4. Red copper: refers to pure copper. The main varieties are oxygen-free copper, red copper, phosphorus-deoxidized copper, and silver copper.
Classification of copper alloys: classified by alloy system
1. Non-alloy copper: Non-alloy copper includes high-purity copper, tough copper, deoxidized copper, oxygen-free copper, etc. People usually call non-alloy copper red copper or pure copper, also called red copper.
2. Other copper alloys belong to alloy copper. my country and Russia divide alloy copper into brass, bronze and nickel silver, and then divide small alloy systems in the major categories.
Classification of copper alloys: by function
1. Copper alloys for electrical and thermal conductivity (mainly non-alloyed copper and micro-alloyed copper.
2. Structural copper alloys: almost all copper alloys.
3. Corrosion-resistant copper alloys: mainly tin brass, aluminum brass, various non-nickel copper, aluminum bronze, titanium bronze, etc.
4. Wear-resistant copper alloys: mainly complex brass and aluminum bronze containing lead, tin, aluminum, manganese and other elements.
5. Free-cutting copper alloys: 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, etc.
8. Art copper alloy: pure copper, simple single copper, tin bronze, aluminum bronze, nickel silver, etc.
Classification of copper alloys: divided into according to the material formation method
1. Casting copper alloy: casting, can also be used for deformation processing.
2. Deformed copper alloy: Deformed copper alloy can be used for casting.
3. Casting copper alloy and deformed copper alloy can be further subdivided into casting copper, brass, bronze and nickel silver.
