What matters most when your front wheel hits a hidden rock on a high-speed descent? It's not aesthetics or minimal weight—it's absolute confidence in your equipment. This core principle is why 7075 aluminum alloy is the foundation of LUNJE's manufacturing philosophy. This guide isn't about replacing carbon fiber; it's for riders, brands, and engineers who prioritize durability, safety, and proven performance.

Why 7075 Aluminum is the Engineer's Choice for Hardcore Components

Aerospace-Grade Strength: With a tensile strength exceeding 550MPa, 7075 aluminum competes with steel, offering exceptional resistance to impact and deformation for direct power transfer.

Superior Strength-to-Weight Ratio: It enables stronger, lighter structures than standard 6061 aluminum, achieving robustness without unnecessary weight.

Predictable Longevity: Unlike carbon fiber, which can suffer from resin aging and hidden layer damage, 7075 aluminum is a homogeneous metal. It is immune to UV degradation and offers a calculable, reliable fatigue life.

Fail-Safe Visibility: Safety is paramount. A compromised 7075 component will show clear, visible signs of stress (bending or cracking), eliminating the risk of sudden, catastrophic hidden failures.

Real-World Performance: From Enduro to Expedition

For Enduro & Downhill Riders: Turn "unknown fear into manageable cost." 7075 components provide a predictable lifespan and failure mode, enduring repeated impacts and reducing long-term equipment risk.

For Gravel & Expedition Touring: Gear reliability is your safety net. The exceptional fatigue resistance of 7075 ensures components withstand thousands of miles of vibration, while its anti-aging properties guarantee performance in all weather conditions.

For Brands & Procurement Managers: This is about supply chain risk management. Our vertical integration and precision manufacturing ensure batch-to-batch consistency, safeguarding your brand from quality recalls and providing dependable performance for team athletes.

The LUNJE Manufacturing Edge: Precision Forging & CNC Mastery

We are specialists in transforming 7075 aluminum into high-performance components.

3D Hot Forging: Using over 1000 tons of pressure, we forge parts to optimize the metal's internal grain structure. This process increases impact toughness by over 30% compared to CNC-machined billet, creating a foundation of inherent strength.

5-Axis CNC Machining: We achieve perfect tolerances, clean interfaces, and flawless finishes, ensuring seamless integration and reliable function in every component.

Vertical Integration & OEM/ODM Expertise: We control the entire process, from material sourcing to final packaging. This allows for stringent quality control, shorter lead times, and true partnership in custom development—from DFM analysis to high-volume production.
