Some friends have asked, how to distinguish T1, T2, and T3 copper? Today, I'll give you a brief explanation.
T1, T2, and T3 are grades of red copper.
Simply based on purity, T1 copper is undoubtedly the purest of the three, with a purity of 99.95%. T2 copper has a purity of approximately 99.90%, slightly lower than T1. T3 is relatively low, generally around 99.70%.
So, how do you distinguish these three grades of copper?
First, can we tell them apart with the naked eye? Through careful observation and comparison, we can.
T1 copper has the brightest, purple-red color, a good gloss, and a delicate feel, thanks to its high purity, fine texture, and pure color.
T2 copper is slightly darker than T1 copper and has a less smooth surface.




T3 copper is more dark red in color and feels rougher. In terms of hardness, T1 and T2 are similar; both are relatively soft and can be scratched with a fingernail with minimal scratching.
T3 is slightly harder, and can leave a mark with a fingernail.
In terms of electrical conductivity, T1 is undoubtedly the best, so it is primarily used for high-precision electrical equipment, wires and cables, and electronic components.
T3 has the worst electrical conductivity, but it has higher strength, so it can also be used for general hardware tools, rivets, nuts, and other mechanical parts.
T2 is in the middle and is primarily used for conductive bars, heat sinks, and pipes.
The company has a cluster of leading copper processing production lines in China, including:
German imported precision copper tube production line (annual output of 30,000 tons)
Japanese technology copper foil rolling line (thinnest up to 6μm)
Fully automatic copper bar continuous extrusion line
Intelligent copper sheet and strip finishing mill unit
Digitalized control and management of the whole production process is realized through MES system, and the dimensional accuracy of the products can reach ±0.01mm.
