Product Introduction

Henan Gnee New Material Co., Ltd. is one of the most professional manufacturers and suppliers of t3 copper pipe for precision engineering industries in China, specialized in providing high quality copper products with competitive price. Welcome to buy discount t3 copper pipe for precision engineering industries for sale here from our factory. Customized orders are welcome.

 

The Brinell hardness of T3 copper is usually 50-70 HB (Brinell hardness unit). This moderate hardness allows T3 copper to be easily shaped during processing while maintaining adequate wear resistance and durability.T3 copper has superior electrical conductivity, with conductivity approaching 100% IACS (International Annealed Copper Standard). Specifically, T3 copper violet typically has a conductivity of 57-58 MS/m (Mega Siemens per meter), which makes it a commonly used material in electrical and electronic equipment.
