The report provides a detailed analysis essential for establishing a tellurium copper strips production plant. It encompasses all critical aspects necessary for tellurium copper strips production, including the cost of tellurium copper strips production, tellurium copper strips plant cost, tellurium copper strips production costs, and the overall tellurium copper strips production plant cost. Additionally, the study covers specific expenditures associated with setting up and operating a tellurium copper strips production plant. These encompass production processes, raw material requirements, utility requirements, infrastructure needs, machinery and technology requirements, manpower requirements, packaging requirements, transportation requirements, and more.
Tellurium copper strips are flat, rectangular forms of a copper alloy containing a small amount of tellurium (0.4-0.7%), having excellent machinability, high electrical and thermal conductivity (90-97% IACS), corrosion resistance, and formability. In the plumbing and building sectors, they produce fixtures, sprinkler heads, fittings, piping, and valves due to their durability and resistance to hydrogen embrittlement.
They are used in the electrical and electronics industries for connectors, relays, switch parts, motor components, transistor bases, circuit boards, high-voltage DC relays, wire/cable, integrated circuits, and semiconductor bases. Their short-chip formation is used in precision machining for dies, tool parts, EDM electrodes, screw machine products, forgings, bolts, studs, welding/soldering tips, and hot-forged components. Additional sectors like aerospace, defence, electric motors, and heat exchangers utilise their strength (tensile ≥280 MPa), bending performance (R/t ≤1.0), and high-temperature stability (≥400 degree Celsius softening resistance).
The market demand for tellurium copper strips is driven by the rising demand from the electrical and electronics industries for high-conductivity components like connectors, relays, and circuit boards, fuelled by 5G expansion, device miniaturisation, and EV infrastructure needs. Additionally, automotive electrification drives growth through lightweight terminals and busbars, amid rising EV adoption.
Moreover, industrial automation favours their machinability for precision parts like EDM electrodes, while Asia-Pacific production hubs accelerate uptake despite raw material volatility and sustainability pushes for recycled alloys. However, industrial tellurium copper strips procurement depends on raw material availability and pricing volatility, as tellurium sourced from copper anode sludges fluctuates with global copper refining output and geopolitical supply chain disruptions.
Raw Material for Tellurium Copper Strips Production
According to the tellurium copper strips production plant project report, the raw material for Tellurium copper strips production includes electrolytic copper.
Production Process of Tellurium Copper Strips
The extensive tellurium copper strips production cost report consists of the following major industrial production process:
- Production from electrolytic copper: The production process of tellurium copper strips begins with smelting electrolytic copper at 1130-1180 degree Celsius, sequentially adding Cu-Te, Cu-P, and Cu-RE master alloys under argon, followed by semi-continuous casting into ingots. In the next step, the ingots undergo homogenisation at 850-950 degree Celsius for 3-4 hours, followed by hot rolling with >90% reduction to break the as-cast structure. The next step involves further homogenisation at 750-850 degree Celsius for 4-8 hours to refine grains and spheroidize tellurides, with RE enriching boundaries for improved plasticity. Finally, cold working achieves a 60-75% reduction, and final stress-relief annealing balances microstructure to yield a hardness of 90-120 HV1, tensile strength ≥280 MPa, elongation ≥15%, conductivity ≥97% IACS, softening resistance ≥400°C, and R/t ≤1.0 bendability.
Properties of Tellurium Copper Strips
Tellurium copper strips (alloy C14500) have a density of 8.9 g/cm³, a melting point near 1081 degree Celsius, and a high thermal conductivity of 355-370 W/m·K, supporting effective heat management. They deliver 90-94% IACS conductivity (resistivity 0.0187-1.86 µΩ·m), ideal for high-performance electrical components. Their mechanical properties include elastic modulus of 110-125 GPa, specific heat of 385-388 J/kg·K, thermal expansion of 17×10-6/ degree Celsius, and tensile strength of 220-330 MPa for robust formability. The alloy comprises ≥99.5% copper, 0.4-0.7% tellurium, and 0.004-0.012% phosphorus, which provide corrosion resistance, hydrogen embrittlement resistance, and arc erosion protection.
