Analysis of aluminum rod cost structure
The cost of aluminum rod is mainly determined by factors such as raw materials, energy consumption, processing technology and regional transportation. Combined with the current market dynamics (as of May 2025), the specific composition is as follows:
1. Raw material cost (accounting for 60%-70%)
Primary aluminum cost:
The production of 1 ton of aluminum ingot requires about 1.95 tons of alumina (unit price of about 2,100 yuan/ton), 15,000 kWh of electricity (electricity price of 0.34 yuan/kWh) and anode carbon blocks (cost of about 1,280 yuan/ton), which together account for more than 60% of the total cost of aluminum rods.
In 2025, about 64% of the electrolytic aluminum production capacity has a cost of less than 16,000 yuan/ton, and the fluctuation of raw material prices directly affects the production cost of aluminum rods.
Recycled aluminum cost:
The purchase price of scrap aluminum is significantly affected by quality and market supply and demand, and processing requires additional smelting and refining processes (energy consumption costs account for 10%-15%). At present, there is a shortage of scrap aluminum raw materials, and the prices of recycled aluminum rods and aluminum liquid rods are inverted. Downstream companies are more inclined to purchase aluminum liquid rods.
2. Energy and processing costs (accounting for 20%-30%)
Energy consumption:
The melting and extrusion processes consume a lot of electricity, and the electricity cost per ton of aluminum rod is about 5,100 yuan (converted according to the electrolytic aluminum stage). Some companies reduce energy consumption through intelligent transformation, but electricity price fluctuations are still sensitive to costs.
Processing costs:
Extrusion molding (accounting for 20%): The complexity of the section affects the mold cost. For example, the extrusion cost of architectural aluminum profiles increases by 10%-30% due to special-shaped structures.
Surface treatment (such as oxidation): The cost of anodizing is about 500-1000 yuan/ton, depending on the processing time and equipment depreciation.
3. Logistics and regional differences (accounting for 5%-15%)
Transportation costs:
The transportation costs of cross-regional sales of aluminum rods are significant, depending on the distance.
IV. Indirect costs (accounting for 5%-10%)
Including equipment maintenance (depreciation of extruders and smelting furnaces), labor (skilled workers' wages account for 10%) and environmental protection costs (investment in wastewater recycling systems).
Cost change drivers
Factors Influence mechanism Aluminum price fluctuations The rise in electrolytic aluminum prices has led to a simultaneous rise in the cost of aluminum rods, and the profit margin of extrusion processing has narrowed
Energy consumption policy The dual carbon goals have promoted the proportion of recycled aluminum to 40%, reducing dependence on primary aluminum but increasing investment in recycling technology
Summary: The cost of aluminum rods is dominated by aluminum ingot prices, energy efficiency and regional logistics. The current limited production capacity of recycled aluminum and the rebound in electrolytic aluminum prices have put pressure on industry profits. Leading companies optimize their cost structure through high-end products (such as photovoltaic profiles).
