T2 Copper belt
T2 copper belt sometimes a small amount of deoxidizing elements or other elements are added to improve the material and performance, so it is also classified as copper alloy.
T2 copper refers to the copper-silver alloy, in which the copper + silver content of copper >99.9% is sufficient, there is no requirement for phosphorus. Conductivity ≥56Ms/m, resistance ≤0.0178×10-6 Ω. M.
- Grade: T2
- Electrical conductivity > 56
- Pure copper strip (hard, ≥0.3mm)
- Density: 8.9g /cm³
- Executive standard: GB/T 2059-2017
- Resistance < 0.017241
Advantage :
- Rolled Copper Foil has extraordinary strength,
bendability, ductility and lustrous surface,
plus its excellent mechanical capacity,
makes it irreplaceable as a raw material. - Especially when used for transformer, Copper Flexible Connector, CCL, FCCL, PCB, Geothermal Film, Construction, Decoration etc.
- The copper foil made by Lion can be customized for different temper, which including soft, quarter hard,half hard , hard temper, even special soft and special hard temper.
T2 Copper Strip characteristics and scope of application
T2 Copper Strip: good electrical conductivity, heat conduction, corrosion resistance and machining properties, can be welded and brazed.
Containing lower conductivity and thermal conductivity impurities, trace oxygen has little effect on conductivity, thermal conductivity and processing properties, but easy to cause “hydrogen disease”, not suitable for processing (annealing, welding, etc.) and use in high temperature (such as >370°C) reductive atmosphere.
Usage: Used as electrical, heat conduction and corrosion resistant equipment. If wire, cable, conductive screw, blasting with detonator, chemical evaporator, storage and all kinds of pipelines.

Brief Information :
Lion T2 Copper Strip(RA Copper Foil) is rolled from pure copper ingots, the process including purifying copper ores, make into copper cathodes, ingoting, rolling, annealing, washing, testing, slitting and packing. Our copper ores are imported from South America, which were famous for their copper mining.
110-anneal (Electrolytic Tough Pitch or ETP) dead soft. Min 99.96% CU
This is high quality copper and has a wide range of applications based on conductivity, corrosion resistance, workability, and beauty.
