In China, the domestic aluminium scrap accounted for 89% of the total raw materials of secondary aluminium, meaning that the production of secondary aluminium has been more independent. China’s secondary aluminium production capacity has reached 14 million mt, accounting for about 30% of the global total secondary aluminium production. And it has become the world's largest producer of secondary aluminium.

SHANGHAI, Oct 13 (SMM) - In China, the domestic aluminium scrap accounted for 89% of the total raw materials of secondary aluminium, meaning that the production of secondary aluminium has been more independent. China’s secondary aluminium production capacity has reached 14 million mt, accounting for about 30% of the global total secondary aluminium production. And it has become the world's largest producer of secondary aluminium.

The whole industry has been developing in a more balanced pattern. While the scaled recycling enterprises have also become an important supply channel for aluminium scrap, indicating heightening industry concentration ratio.

During the "13th Five-Year Plan" period, China's secondary aluminium output totalled about 34.8 million mt, reducing the extraction of aluminium ore by 139.2 million mt, conserving the utilisation of standard coal and water by 120 million mt and 770 million cubic metre, respectively, and reducing the discharges of carbon dioxide and solid waste by 380 million mt and 696 million mt, respectively.

China's secondary aluminium industry has made great achievements in the past, but it should also be pointed out that China’s proportion of secondary aluminium in the total aluminium production is still at the level of developed countries in the eighties.

According to the resource and consumption forecast, China's aluminium consumption is expected to reach a peak by 2024, after which it will basically be in a plateau period, with primary aluminium production gradually shrinking due to policy and economic reasons; while the production of secondary aluminium will ramp up year by year, and the proportion in total consumption will gradually increase.

By 2025, China's secondary aluminium production will reach 11.5 million mt; the aluminium scrap utilisation efficiency and the added value of products will both be improved; the technical level of secondary aluminium and the equipment will be significantly enhanced; the degree of harmless treatment of aluminium ash and the utilisation rate of resources will be further improved. By 2030, the output of secondary aluminium will reach 18 million mt; the secondary aluminium processing technology will reach the international advanced level; a sophisticated industrial system will be formed; and the utilisation rates of aluminium ash and other solid wastes will reach 100%.

Ferrous Metals May Rebound Slightly Next Week [SMM Steel Industry Chain Weekly Report]

This week, ferrous metals mostly retreated after rapid rises, with only coking coal and coke standing out, briefly hitting the daily limit up at the open. Early in the week, the market was primarily characterized by coking coal and coke leading the gains across ferrous metals. A coal mine accident occurred in Shanxi over the previous weekend, strengthening market expectations of tighter supply driven by stricter subsequent regulatory oversight and increased production shutdowns at coal mines. Ferrous metals rebounded on cost support. However, some coal mines quickly resumed production afterward, and combined with the prospect of a US-Iran deal being reached, crude oil declines dragged iron ore prices lower, loosening cost support. Most products except coking coal and coke retreated from highs. In the latter half of the week, data on the five major steel products were released, showing continued inventory destocking but marginally weakening apparent demand, with supply-demand pressure rising somewhat. Spot market side, spot prices remained relatively firm this week, with the spot-futures price spreads for both hot-rolled coil and rebar widening, providing shipment opportunities for basis traders, while end-users continued to restock on a need-based, low-price approach...

Copper Scrap Payability Coefficients Hold Exceptionally Firm as Supply-Demand Mismatch Defies Traditional Market Logic

In May, copper prices surged before retracing, yet copper scrap payability coefficients remained exceptionally firm. Transactions for Millberry stabilized at a high level of 98.5%, while No. 2 copper became the market highlight, with its coefficient climbing from around 95% to 96%–97% due to the premium upside of its gold and silver by-products. Driven by stricter domestic policies and tax compliance, China demand remained robust. Conversely, tight overseas scrap supply persisted, and this structural mismatch kept import payability coefficients elevated and sticky for the short term. Under the current landscape of tight global supply and resilient demand, the traditional market logic of "surging copper prices driving down payability coefficients" has effectively become obsolete.

ADC12 Aluminum Alloy Market Sees Slight Rise Amid Cost Pressures and Tight Scrap Supply

[SMM Aluminum Alloy Daily Review] The ADC12 aluminum alloy market was generally stable with slight rise today. Driven by cost pressure, some enterprises raised their quotes slightly by 100 yuan/mt, while most manufacturers remained steady and took a wait-and-see approach. Currently, invoiced aluminum scrap resources remained persistently tight, pushing up procurement costs, and some manufacturers were concerned about potential production reduction risk. However, downstream demand remained mediocre, with limited end-user order release, which constrained price increases.
