Premium Custom 7075 Aluminum Extrusion Tubes - 33 Years of Expertise in Precision Extrusion
As a leading 7075 aluminum extrusion tubes manufacturer with over 33 years of experience, Zhonglian Aluminum specializes in delivering high-performance aluminum solutions tailored to diverse industrial needs. Our custom 7075 aluminum tubes are engineered through advanced extrusion processes, combined with one-stop aluminum services ranging from mold design to CNC machining, ensuring unmatched flexibility and quality.
Our custom 7075 aluminum extrusion tubes represent the pinnacle of aluminum alloy performance. Manufactured from aerospace-grade 7075 alloy, these tubes undergo precise aluminum extrusion and subsequent heat treatment (typically T6 or T651 temper) to achieve exceptional strength-to-weight ratio, superior fatigue resistance, and excellent machinability. They are the go-to choice for structural components subjected to high stress, impact, and challenging environments.
At Zhonglian Aluminum, we understand that every project has unique requirements. Our design flexibility includes:
- Custom Mold Development: Tailored dies for unique cross-sections, supporting complex geometries and specifications.
- Size Customization: OD from 6mm to 300mm, wall thickness from 1mm to 50mm, and lengths up to 12 meters.
- Material Optimization: Engineering solutions to balance strength, weight, and cost for specific applications.
- Rapid Prototyping: Short lead times for sample validation before mass production.
