Top-Selling Aluminum Alloys at Tennentong in 2026 (Ranked by Shipment Volume)

6063 (Best-Seller)

Primarily used for architectural curtain walls, doors and windows, decorative frames, and industrial assembly line racks. It offers excellent extrudability and a high-quality anodized finish. With large stock availability, it is the most widely used alloy in the construction industry. Common tempers: T5, T6.

6061

Used for machining, automation frames, tooling, and various forms (plates, rods, and tubes). It offers a well-balanced set of properties—suitable for CNC machining, welding, and anodizing—and is the most frequently requested alloy by B2B international trade clients. Common temper: T6.

5052

Ideal for sheet metal fabrication, bending, fuel tanks, equipment enclosures, and general outdoor components. It is easy to bend, welds well, offers reliable rust resistance, and sees high shipment volumes in sheet form. Common temper: H32.

1060 (Popular Pure Aluminum)

Used for conductive busbars, heat sinks, signage, linings, and corrosion-resistant applications in the chemical industry. It features excellent thermal and electrical conductivity, is easy to polish, and is affordably priced.

5083

Designed for marine vessels, coastal equipment, storage tanks, and seawater-exposed environments. It offers strong resistance to chloride ions and excellent low-temperature performance; it is a steady choice for marine-related projects. Common tempers: H111, H116.

6082 (Popular in Europe)

Compliant with European EN standards for structural components. Often used as an alternative to 6061, it provides higher strength and is frequently utilized in construction machinery and automotive structural parts; it sees high demand in overseas markets.

7075 (High-End Series)

Known for high strength and lightweight properties. Used in aerospace, mold-making, racing, and high-end tooling. While the price is higher and shipment volumes are lower, the high value per unit makes it a sought-after premium product.

Important Supplementary Notes

5000-series (rust-resistant) aluminum alloys cannot be hardened by heat treatment; their strength is instead enhanced through strain hardening (H-temper). 6000- and 7000-series alloys rely on T6 heat treatment to achieve high strength.

7075 aluminum is not suitable for long-term exposure to humid, coastal environments, as it is prone to pitting corrosion.

For any given alloy grade, the temper (e.g., T6, H32, or O) significantly impacts performance; therefore, the temper must be specified in any price quote.

Cost ranking (from lowest to highest): 1060 < 5052 < 6063 < 6061 < 5083 < 7075.

Market trends: 6000-series profiles are the most sensitive to fluctuations in aluminum ingot prices, whereas 5000-series sheets show more stable pricing. 7075 is considered a high-end material; due to limited production capacity, it commands a higher premium and typically entails longer lead times.
