Classification of copper alloys
Dec 22,2022
There are three ways to classify copper alloys:
By alloy
According to the alloy system, it can be divided into non-alloy copper and alloy copper. Non-alloy copper includes high-purity copper, tough copper, deoxidized copper, oxygen-free copper, etc. Traditionally, people call non-alloy copper red copper or pure copper, also known as red copper, while other copper alloys belong to alloy copper. In China, alloy copper is divided into brass, bronze and white copper, and then divided into small alloy systems in large categories.
By function
According to function, there are copper alloys for conducting heat conduction (mainly unalloyed copper and microalloyed copper), structural copper alloys (almost all copper alloys), corrosion-resistant copper alloys (mainly tin brass, aluminum brass, various kinds of non-white copper, aluminum bronze, titanium bronze, etc.), wear-resistant copper alloys (mainly complex brass, aluminum bronze, etc. containing lead, tin, aluminum, manganese and other elements), free-cutting copper alloys (copper lead, copper tellurium, copper antimony and other alloys) Elastic copper alloy (mainly antimony bronze, aluminum bronze, beryllium bronze, titanium bronze, etc.) Damping copper alloy (high manganese copper alloy, etc.), art copper alloy (pure copper, simple copper, tin bronze, aluminum bronze, white copper, etc.). Obviously, many copper alloys have multiple functions.
Material forming method
According to the material forming method, it can be divided into cast copper alloy and deformed copper alloy. In fact, many copper alloys can be used for both casting and deformation processing. Generally, deformed copper alloys can be used for casting, but many cast copper alloys can not be used for deformation processing such as forging, extrusion, deep drawing and drawing. Cast copper alloy and deformed copper alloy can be subdivided into red copper, brass, bronze and white copper for casting.
