Tellurium Copper Busbar/ Strip

Tellurium copper busbars are rectangular, round or special-shaped conductive bars made by rolling or extruding tellurium copper alloys (such as C14500). They have high conductivity and excellent machining properties and are suitable for electrical connection scenarios that require precision machining, high current carrying or complex shapes.

product introduction

Tellurium copper is a copper alloy containing a small amount of tellurium (Te), usually between 0.4% and 0.7%. This alloy combines the excellent electrical conductivity and thermal conductivity of copper with the easy cutting property of tellurium, and can meet the low temperature rise and high voltage arc resistance test at the application end, and is suitable for high-voltage DC relays, connectors, automotive terminals, etc.

1、Main characteristics of tellurium copper busbar

Characteristics	Parameters/Description
Conductivity	≥90% IACS (close to pure copper, better than ordinary brass)
Cutting performance	Excellent (tellurium content 0.4%~0.7%, reducing tool wear, suitable for CNC processing)
Tensile strength	Soft state (O): 200~250 MPa; Hard state (H): 300~350 MPa
Elongation	Soft state: ≥25%; Hard state: ≥5%
Hardness	HRB 40~80 (different hardness states can be customized)
Corrosion resistance	esistant to corrosion by air, water, and non-oxidizing media, but avoid environments such as hydrogen sulfide and ammonia
Weldability	Can be soldered, silver soldered, and argon arc welded, but attention should be paid to tellurium volatilization during high-temperature welding (ventilation is recommended)
