Advantages of 7075 T6 Aluminum Blocks

1. Stable Machinability

7075 T6 aluminum blocks, when machined after stress relief, effectively avoid deformation and warping. All ultra-thick 7075 aluminum blocks undergo ultrasonic testing to ensure there are no sand holes or impurities, enhancing the material's consistency and reliability. Additionally, 7075 aluminum blocks have high thermal conductivity, which reduces molding time and significantly improves machining efficiency.

2. Excellent Physical Properties

7075 aluminum blocks exhibit exceptional physical properties, including good strength, hardness, and tensile performance. Their machinability is also outstanding, adaptable to various machining methods. At the same time, 7075 aluminum blocks have good corrosion resistance, especially after aging hardening treatment, which allows for higher strength while maintaining excellent performance in harsh environments.

3. High Strength Natural Aging

Even under natural aging conditions, 7075 aluminum blocks can achieve high strength with low sensitivity to cracking. This means that during machining and use, 7075 aluminum blocks can withstand greater stress without easily developing cracks or other defects, thereby enhancing their reliability in various applications.

4. Weld Strength Recovery

During welding, the heat from the welding area can cause localized material melting in 7075 aluminum blocks. However, after natural aging, the strength of these welded areas can be restored. This characteristic results in high weld strength for 7075 aluminum blocks, making them suitable for applications requiring welding, ensuring the overall structural safety and reliability.
