Independently developed and produced by Shanghai Perfect Industry Co., Ltd., 2xxx Serious Aluminum Alloy Bars are high-strength structural metals built on an aluminum-copper alloy system. With aluminum content usually above 90% and copper content between 2%–5%, the copper additive is key to enhancing the alloy’s tensile strength and hardness, while trace elements optimize its fatigue resistance and machinability. Endowed with superior load-bearing capacity and structural stability, these bars are widely applied in high-demand fields requiring top-tier strength and reliability, and stand as a core material for aerospace, automotive manufacturing, and precision machinery industries.
1. Higher upper limit of strength and stability
2. Better machinability and processing efficiency
3. A more comprehensive solution to corrosion resistance
4. More flexible specification customization and delivery capabilities
5. Higher cost performance and cost advantage
6. More authoritative quality certification and traceability

1.Inner Packaging: Each bar is wrapped with moisture-proof, scratch-resistant PE film to prevent oxidation, corrosion, and surface scratches during transportation and storage.
2.Outer Packaging: Use high-quality wooden pallets or steel frames for fixing, and bundle with high-strength steel straps to ensure stability during long-distance transportation and ocean shipping. For small-diameter bars, use cartons or iron drums for packaging.
3.Custom Packaging: Support customized packaging solutions according to customer requirements (such as vacuum packaging, fumigation-free wooden pallets, anti-rust packaging) to adapt to different transportation methods and storage conditions.
1. Q: Do you provide samples? How to apply for samples?
A: We provide free samples (customers only need to bear the shipping cost). You can contact our sales team via email or phone to provide your company information and product requirements, and we will arrange sample delivery.
2.Q: What payment methods are supported?
A: We support T/T, L/C, and other international common payment methods. Specific payment terms can be negotiated according to the order quantity and cooperation mode.
3.Q: How to ensure the product quality during transportation?
A: We use professional packaging methods suitable for long-distance transportation, and cooperate with well-known logistics companies with rich experience in international transportation to minimize the risk of product damage during transportation. At the same time, we can purchase transportation insurance for customers according to their needs.
4.Q: Are you manufacturer or trader?
A: We are a group company consisting of two trading companies, two warehouses, and one factory. We maintain a standing inventory of 5,000 tons and operate two production lines. Shanghai Perfect Industrial Co., Ltd. is primarily responsible for overseas sales. We are also an authorized distributor for several state-owned factories in China.
