Aluminum 7075 CNC Machining – High-Strength Precision Parts – Ranglink

Precision CNC Machining for Aluminum 7075 Parts

Aluminum 7075 is a high-strength aerospace-grade alloy, known for its exceptional strength-to-weight ratio and excellent fatigue resistance. It is one of the hardest aluminum alloys available, often used in applications where 6061's strength is insufficient. At Ranglink, we specialize in CNC machining of Aluminum 7075 for demanding prototypes and production runs.

✈️ Why choose 7075?
– Highest strength among common aluminum alloys.
– Excellent fatigue resistance.
– Good anodizing response.
– Ideal for highly stressed components in aerospace, defense, and high-performance automotive.

Surface Treatment Options for Aluminum 7075

Anodizing (clear, black, colored) Hardcoat Anodizing (Type III) Powder Coating Bead Blasting Brushing Laser Marking Silkscreen

Note: Due to the copper content in 7075, anodizing may produce a slightly darker finish compared to 6061. Hardcoat anodizing is highly recommended for wear resistance.
