【King of Conductivity】1060 Alloy (aluminum Content 99.6%), Ultra-wide 1500mm, Special for Power Industry

Decoding of core characteristics: Why has 1060 alloy become a rigid demand in the power industry?
The king of electrical conductivity

The aluminum content is ≥ 99.6%, and the electrical conductivity is up to 61% IACS (International Annealed Copper Standard), which is second only to copper but the cost is reduced by 60%, and the conductivity per unit weight is better than that of copper (density of only 2.7g/cm³).

The ultra-wide 1500mm design reduces the splicing nodes and reduces the resistance loss (the resistance of the narrow splice is increased by about 8-12%).

Industrial-grade reliability

Corrosion resistance: Natural oxide film surface coating (optional anodizing or chemical passivation), salt spray test > 2000 hours (according to ASTM B117).

Ductility: tensile strength 60-95MPa, can be cold-rolled into complex cross-sections (such as hollow busbars, special-shaped wires), suitable for high-voltage equipment precision machining.

Green economy

Lightweight reduces the load of transmission towers and reduces the amount of steel structures by more than 20%.

100% recyclable, with 75% lower carbon emissions than copper production (International Aluminium Association data).

International Application Scenario: The "Aluminum-based Code" of the Global Power Revolution
1. High-voltage power transmission
European and American markets: used for overhead conductors above 500kV aluminum core (AAAC wire), ultra-wide reduction joints to improve safety (such as the German Tennet high-voltage power grid renovation project).

China UHV: ± aluminum tube bus and equalizing ring in 1100kV DC project, 1500mm wide to reduce welds, passed IEC 61284 corona resistance test.

2. New energy power equipment
Photovoltaic inverter: ultra-wide aluminum plate integrated stamping shell, heat dissipation efficiency increased by 30% (SolarEdge factory case in Spain).

Wind power converter: 1500mm wide aluminum bar instead of copper bar, reducing weight by 40% and reducing cost by 25% (Vestas offshore wind power project in Denmark).

3. Urban power grid upgrades
Japan Smart Grid: Wide aluminum cable tray for underground distribution channels, resistant to moisture and electromagnetic interference (TEPCO Smart City Plan 2025).

Southeast Asia Power Grid Transformation: High-temperature resistant aluminum conductor (150°C long-term operation) to solve the transmission bottleneck in tropical areas (Indonesia PLN National Grid Project).

4. Power equipment manufacturing
Transformer heat sink: One-piece wide aluminum fin, 18% higher thermal conductivity (ABB Swiss plant technical solution).

Nuclear equipment: nuclear-grade passivated aluminum is used in reactor auxiliary system pipelines (EDF nuclear power plant supply chain certified product).

Future trend insights: technology iteration and market breaking points
1. Ultra-wide technology innovation
R&D of 2000mm ultra-extreme width: reduce the welding joints of power transmission projects by 90%, and target to be applied to UHVDC projects above 800kV ± (China XD Group 2026 Roadmap).

Composite Coating Technology: Graphene Reinforced Aluminum Matrix Composites (GRC-Al) Increase Conductivity to 65% IACS (3M Laboratories Prototype Testing Stage).

2. Driven by new energy scenarios
Hydrogen energy storage and transportation: Wide aluminum plate is used for the conductive layer of liquid hydrogen storage tanks, which is compatible with -253°C ultra-low temperature environment (EU HySupply 2030 plan).

Solid-state battery connectors: Demand for high-purity aluminum foil is surging (CATL forecasts global demand to reach 500,000 mt/year in 2027).

3. Intelligence and standardization
Digital twin integration: Aluminum conductivity data is embedded in IoT systems (such as Siemens' MindSphere platform) to enable real-time optimization of grid losses.

From UHV silver wires crossing mountains and rivers to the cryogenic challenge of hydrogen energy storage tanks, 1060 ultra-wide aluminum is reconstructing the underlying logic of the power industry with the advantages of "light, strong and conductive". Driven by the goal of carbon neutrality and the energy revolution, this silent revolution of "replacing copper with aluminum" will continue to release hundreds of billions of market dividends, and enterprises that have mastered ultra-wide core technologies will become the "rule-makers" of the next generation of energy infrastructure.
Harmonization of international standards: The revised draft IEC 62004 includes wide aluminum (≥1200mm) in the recommended standard for high-voltage equipment (effective 2025).

4. Circular economy closed loop
Aluminum scrap direct melting recycling technology: 1060 alloy is recycled in grade, and the carbon emission is reduced by 95% compared with primary aluminum (the Hydro CIRCAL project in Norway has been commercialized).

Carbon footprint certification: The EU CBAM carbon tariff forces the power industry to purchase low-carbon aluminum (fully implemented in 2026).

Data Preview: The "Aluminum-Electric Equation" of the Trillion-Level Market
According to CRU's forecast, the demand for aluminum in the power industry will increase by 7.2% annually from 2023 to 2030, of which the proportion of ultra-wide products will rise from 15% to 35%.

Evolution of key technical indicators:

Conductivity: 61% → 68% IACS (Nanograin Conditioning Technology)

Tensile strength: 95MPa → 130MPa (microalloying process)

Temperature limit: 150°C → 300°C (ceramic composite coating)
