Yuefeng Aluminum Achieves Stable Mass Production of 6 Series High Silicon High Copper Alloy
August 24, 2026
Recently, Yuefeng Aluminum took "Definitely Winning the Four Major Battles" as an important guideline. The entire company actively tackled the challenges, and the melting and casting production line delivered good news - the 6 series high silicon high copper alloy process was finalized, achieving stable mass production. In July, a small batch of high-quality ingots was produced, and the casting yield increased by 20% compared to the initial debugging stage, opening up a new path for the recycling of high copper waste materials.
The 6 series alloy is a typical medium-high strength deformation aluminum alloy, featuring high strength, excellent weldability, and corrosion resistance. It is a key material for aerospace structural components and lightweight automotive body panels. However, the high copper content makes it prone to cracking during casting, and similar products in the industry have a low yield rate, making stable production extremely difficult, which is recognized as a "difficult nut" in the industry.
Overcoming difficulties - Facing this "difficult nut", the process team of Yuefeng Aluminum took on the challenge and launched a full-process research and development. The team conducted repeated experiments, precisely calibrated key parameters such as casting speed, and established a "low-speed start casting - steady-state casting" dynamic curve. In addition, the team strictly controlled the uniformity of components under a high waste ratio and implemented batch tracking and solidified process documents to form standardized operation norms. After multiple rounds of optimization and iteration, the team successfully overcame the problem of hot cracking and achieved stable mass production.
Significant meaning - The significance of this stable production is far more than just "producing". Yuefeng Aluminum's core technology for casting high heat sensitivity alloys enables the product series to achieve a strategic upgrade from 3/5 series to 6 series, enhancing the core competitiveness of the products, actively expanding high value-added product tracks, and seizing the high-end market. The newly established path for recycling high copper waste materials also helps to digest the enterprise's idle waste materials and effectively revitalize the enterprise's funds.
