Why Choose Aluminum Forging for Structural Parts

mountain bike crank arm
  • Higher Strength for Pedaling Load
The combination of forged aluminum and CNC machining provides the crank arm with better strength and internal density, enabling it to withstand repeated pedaling forces, torque, and impacts
  • Better Fatigue Resistance
Bike crank arms work under repeated stress. Aluminum forging helps improve fatigue resistance and long-term reliability
  • Lower Porosity Risk than Die Casting
Forging creates a denser structure with lower porosity risk, making it more suitable for load-bearing bicycle and e-bike components.
  • Better Anodized Appearance
Forged aluminum is suitable for stable anodizing, making it ideal for visible performance parts and branded bicycle components.

Materials and Surface Finishing for Bike Cranksets

6061 Aluminum Forging

A widely used alloy with good strength, machinability, corrosion resistance, and anodizing performance.

6082 Aluminum Forging

Often used for structural aluminum parts requiring higher strength and good machining performance.

7075 Aluminum Forging

Suitable for high-strength applications where mechanical performance is critical.

Surface Finishing

Available finishing includes anodizing, sandblasting, polishing, laser marking, and custom appearance based on brand requirements.
Material selection depends on strength requirements, application environment, surface treatment, and target cost.

FAQ: Aluminum Forging + CNC Machining

Q1. What bike crankset components can XinPingFu manufacture?

A.    XinPingFu can manufacture custom forged aluminum crank arms, bicycle chainrings, crankset parts, spiders, brackets, and related aluminum drivetrain components based on customer drawings.

A.     Yes. We provide aluminum forging, CNC machining, and surface finishing for custom crank arms used in bicycles, mountain bikes, road bikes, and e-bikes.

A.      Common options include 6061, 6082, and 7075 aluminum. The best alloy depends on strength, weight, machining, anodizing, and cost requirements.

A.    Yes. We provide CNC machining after forging for precision holes, threads, surfaces, tight tolerances, and final assembly features.

A.     For load-bearing crank arms, forged aluminum is usually more suitable than die casting because it offers better strength, fatigue resistance, and lower porosity risk.

A.       Yes. CNC machining is used after forging to complete spindle holes, threads, mounting holes, flat surfaces, and tolerance-critical assembly features.

A.       Yes. We can support anodizing, polishing, sandblasting, laser marking, and custom surface appearance based on brand and product requirements.

A.      Send us your 2D/3D drawings, material, crank arm length, surface finish, quantity, and application. Our team will review the best forging + CNC process for your project.
