Technical Advantages for Automotive Engineering

✅ Weight Reduction: Hollow forging technology reduces mass by 15-25% vs solid counterparts
✅ Fatigue Resistance: Directional grain flow extends component life by 3-5X
✅ Thermal Management: Optimized heat treatment prevents warping in high-temp zones
✅ Corrosion Solutions: Zinc-nickel plating options for underbody components

FAQ

1. Material & Specifications

Q: What brass alloys do you use?
A: We primarily use C36000 (Free-Cutting Brass), C46400 (Naval Brass), and C37700 (Forging Brass) for optimal machinability, corrosion resistance, and strength.

Q: Are your parts lead-free/RoHS compliant?
A: Yes, we offer lead-free brass alloys meeting RoHS, REACH, and ELV directives for automotive use.

Q: What are the temperature limits?
A: Standard brass parts operate reliably in -30°C to +150°C; high-temp variants (e.g., C48500) available for up to +250°C.

2. Product Features

Q: Why choose brass for automotive fasteners?
A: Benefits include:
✔ Corrosion resistance (especially vs. salt/brake fluid)
✔ Non-sparking & non-magnetic properties
✔ Excellent thread durability for repeated assembly

Q: Do you offer anti-galling treatments?
A: Yes! Options include:

• PTFE coating for reduced friction

• Electroless nickel plating for wear resistance

Q: Can limiters/washers be customized?
A: Absolutely – we provide:

• Custom thicknesses (0.5–10mm)

• Special diameters/tolerances (±0.05mm)

• Branding/laser marking

3. Performance & Testing

Q: What load capacities do your flange bushings support?
A: Varies by size, but typical ranges:

• Axial load: 5–50 kN

• Radial load: 3–30 kN

Q: How do you ensure quality?
A: Each batch undergoes:
✔ Dimensional checks (CMM/optical comparators)
✔ Salt spray testing (500+ hours for coated parts)
✔ Torque-tension validation for fasteners

Q: Are your parts compatible with OEM specs?
A: Yes – we replicate DIN, ISO, SAE, and JIS standards (e.g., DIN 934 nuts, ISO 4032 washers).

4. Ordering & Logistics

Q: What’s the MOQ?
A: 1,000 pieces (standard items), but negotiable for prototypes.

Q: What’s the lead time?
A:

• Custom parts: 30–45 days (simple), 20–30 days (complex)

Q: How are parts packaged?
A: VCI anti-tarnish bags + carton boxes (bulk pallets available).
