Product Overview

Our HRD series combines lightweight aluminum-magnesium alloys with sintered boron carbide inserts to deliver ultra-hard, wear-resistant components machined to the highest precision. From single-piece prototypes to high-volume runs, we handle every step—CAD optimization, multi-axis CNC milling, boron carbide sintering, post-machining finishes and full inspection.

Key Parameters

Selling Points

1. Wear-Resistant Composite Design
   Integrating sintered boron carbide inserts into an Al-Mg matrix yields parts with exceptional hardness, extending service life in high-abrasion environments.

2. Lightweight Strength
   Aluminum-magnesium alloys offer up to 30% weight savings versus steel while maintaining excellent structural rigidity and corrosion resistance.

3. Tight, Consistent Tolerances
   Multi-axis CNC machining delivers critical features to ±0.01 mm, ensuring seamless assembly and optimal performance in precision systems.

4. One-Stop Production
   From DFM consultation and prototype milling to sintering, finishing and full QA, our turnkey workflow reduces lead times and simplifies supplier management.

5. Custom Finishes & Coatings
   Tailor parts with anodizing, hard-coat treatments or PTFE infusion for further corrosion protection, reduced friction, or chemical resistance.

Future Trends in Hybrid Metal Composites

• Additive-Assisted Sintering
  Combining metal binder jetting with ceramic sintering to create complex B₄C-reinforced geometries without extensive machining.

• Smart Surface Technologies
  Embedding sensor networks or self-lubricating channels within metal-ceramic composites for predictive maintenance and autonomous lubrication.

• Green Manufacturing
  Closed-loop coolant systems, solar-powered sintering furnaces, and scrap alloy recycling to minimize environmental impact.

• High-Entropy Alloy Integration
  Exploring multi-element aluminum-based high-entropy alloys combined with superhard ceramics for next-generation extreme-environment components.

Application Scenarios

• Aerospace Actuation & Landing Gear
  Wear-critical sliding blocks and bearing housings benefiting from low mass and high abrasion resistance.

• Automotive & EV Powertrains
  Cam followers, roller guides and pump components that endure high cycles and contact stresses.

• Defense & Security
  Lightweight, hard-face inserts in soldier-worn equipment, vehicle armor modules and turret bearings.

• Industrial Machinery
  Abrasion-prone components in rock crushers, slurry pumps and ceramic-lining support structures.

• Semiconductor & Chemical Processing
  Corrosion-resistant flow control parts and valve seats requiring ceramic hardness and metal ductility.

Frequently Asked Questions

Q1: What is your minimum order quantity (MOQ)?
Prototypes begin at 1 piece; typical production MOQs range from 10 to 50 pieces depending on complexity.

Q2: What lead times can I expect?

• Prototype (milling + sinter): 7–10 business days

• Small batch (10–100 pcs): 2–3 weeks

• Volume runs (> 100 pcs): 4–6 weeks, subject to order size and finishing options.

Q3: Which CAD formats do you support?
We accept native SolidWorks, STEP, IGES, and 2D DXF/DWG drawings.

Q4: Do you offer post-machining coatings?
Yes—anodizing (Type II/III), PTFE, nickel plating and other specialty coatings are available per your specifications.

Q5: How are parts packaged and shipped?
Finished components are ultrasonically cleaned, lightly oiled or passivated, wrapped in anti-static foam and packed in custom crates or cartons. Worldwide shipping via air, sea or express courier.
