Frequently Asked Questions
What materials are commonly used for these Control Arms?
Our control arms are mainly made of aerospace-grade 6061-T6 aluminum alloy and high-strength alloy steel (42CrMo). 6061-T6 provides a lightweight solution with excellent corrosion resistance, while 42CrMo steel offers extremely high tensile strength for harsh off-road conditions.
What surface treatments are available for durability?
Common treatments include Hard Anodizing (improves wear resistance in multiple colors), Powder Coating (enhances protection), and E-coating (suitable for steel arms with 500+ hours salt spray resistance).
How do you ensure quality and performance during design?
We use SolidWorks for structural design and stress analysis, performing fatigue cycles to ensure durability. We offer customization for size, mounting holes, and materials to meet specific extreme condition requirements.
What is the standard production process and lead time?
The process includes raw material cutting, 5-axis CNC machining (tolerance ±0.01mm), heat treatment, and surface coating. Regular lead time is 30-35 days, while mass production for over 1000 sets takes approximately 45 days.
What customization options are available for enterprise orders?
Customization includes size, mounting interface, material choice (Aluminum/Steel/Carbon fiber), surface finish, color, and logo engraving. We can optimize designs based on your budget.
How should the control arms be maintained?
We recommend inspecting ball joints and bushings every 5000 km. Under normal conditions, aluminum arms have a lifespan of 5-8 years, while steel arms can last 8-10 years.
