7xxx Serious Aluminum Alloy Profiles are ultra-high-strength aluminum-zinc-magnesium-copper alloy products independently developed and manufactured by Shanghai Perfect Industry Co., Ltd. The core feature of this series lies in its aluminum-zinc-magnesium-copper alloy system, with zinc content ranging from 4.0% to 7.0%, magnesium from 1.0% to 3.0%, and copper from 0.1% to 2.0% (specific contents vary by alloy grade). The synergistic effect of these multiple alloying elements forms various strengthening phases, and through sophisticated heat treatment processes (solution treatment + artificial aging), the products are endowed with exceptional mechanical properties. While retaining the inherent lightweight advantage of aluminum alloys (density only 2.81g/cm³), 7-series profiles achieve outstanding tensile and yield strengths. Additionally, they possess excellent fatigue resistance and machinability, making them indispensable key materials in high-end fields that demand ultra-high strength, high reliability, and lightweight performance.

1.Q: Do you provide samples of 7-series aluminum alloy profiles? How to apply?
A: We offer free standard samples (300mm in length for profiles, A4 size for plates), and customers only need to bear the shipping cost. For customized samples (special cross-sectional shape, surface treatment, or size), a certain sample fee will be charged (the sample fee can be deducted from the formal order payment). You can contact our sales team via email or phone, provide your company information, required product specifications, and sample requirements, and we will arrange sample delivery within 5-7 working days (longer than ordinary series due to the complex heat treatment process of 7-series products).
2.Q: What payment methods are supported for international orders?

A: We are a professional manufacturer with our own independent production factory and R&D center. We warmly welcome customers to visit our factory for inspection and can arrange professional staff to receive you and detailedly introduce the production process, equipment, and quality control system.
5.Q: What is the lead time for 7-series aluminum alloy profiles?
A: For standard specifications and in-stock products, the delivery time is 10-15 working days; for customized products, the delivery time is 20-40 working days (due to the more complex and time-consuming heat treatment process), depending on the customization difficulty and order quantity. We will confirm the specific delivery time with customers before placing the order.
•Free Standard Samples: The size is 300mm in length for profiles or A4 size for plates, and customers only need to bear the shipping cost. Samples include common surface treatments such as natural anodizing and passivation treatment.
