CR450 powder metallurgy brake pads for high-speed trains

1. Stable and Reliable Friction Performance

Our railway brake pads are manufactured in strict compliance with railway industry standards to ensure stable braking performance under all operating conditions.

Wet / rainy conditions:

Composite brake pads maintain an average friction coefficient ≥ 0.210, while powder metallurgy brake pads achieve ≥ 0.250, ensuring safe and stable braking without slipping in wet environments.

Static friction performance:

Standard vehicle models ≥ 0.350, C.11 / C.12 vehicle types ≥ 0.320, ensuring secure parking braking performance without wheel roll.

Continuous braking stability:

During prolonged braking, the instantaneous friction coefficient remains stable within 0.250–0.500, with fluctuation controlled within ≤ 0.050 per minute. The system features excellent thermal stability with minimal friction fade and consistent braking force.

2. Excellent Wear Resistance for Extended Service Life

Our advanced friction material formulation significantly improves wear resistance and reduces maintenance costs.

Powder metallurgy brake pads wear rate: ≤ 0.35 cm³/MJ

Composite brake pads wear rate: ≤ 0.55 cm³/MJ

The products ensure long-term stable operation without abnormal wear, effectively reducing replacement frequency and making them suitable for high-speed rail, heavy-haul railway, and other high-load applications.

3. Reliable Physical and Mechanical Properties

Powder Metallurgy Brake Pads:

Density: (1 ± 0.1) g/cm³ (controlled within nominal value)

Hardness: 10–30 HBW

Shear strength: ≥ 6 MPa

Bonding shear strength (friction layer to back plate): ≥ 7 MPa

Compressive strength: ≥ 60 MPa

High impact resistance, excellent structural stability, and resistance to fracture or detachment

Composite Brake Pads:

Density: (1 ± 0.05) g/cm³ (controlled within nominal value)

Hardness: 30–90 HRR / HRX

Impact strength: ≥ 3.0 MPa

Compressive strength: ≥ 20 MPa

Compression modulus: ≤ 1000 MPa

Excellent toughness and deformation resistance for stable long-term operation

4. Environmentally Friendly and International Standard Compliant Formulation

Our brake pads are designed with safety, environmental protection, and international compliance in mind.

Free from hazardous substances:

No asbestos, lead, zinc, cadmium, or hexavalent chromium. The production and application process does not release harmful dust or gases, fully compliant with GB/T 5085.3-2007 and GB/T 30512-2014 environmental standards.

Low-metal optimized formulation:

Total content of aluminum and silicon in powder metallurgy materials is ≤ 1%, while chromium, zirconium, and tungsten combined content is ≤ 10%. This reduces wear on brake discs and extends the overall service life of the braking system.

Q1: What is your company background? Are you a reliable railway supplier?

A: We are one of the early manufacturers in China specializing in high-speed train braking components. We have long-term cooperation with China Railway Corporation and CRRC, supplying critical braking system components for multiple high-speed railway lines. Our products have been widely verified in national railway projects, ensuring stable quality, strong production capability, and reliable long-term supply performance.

Q2: How is your manufacturing process and quality control system?

A: We adopt advanced powder metallurgy and precision manufacturing processes, supported by a full-process quality control system covering raw materials, production, and final inspection. Our laboratory is accredited by CNAS, enabling comprehensive performance testing to ensure all products meet strict railway industry safety and reliability standards.

Q3: Do you have professional performance testing capabilities?

A: Yes. We are equipped with a 1:1 LINK friction testing bench that simulates real braking conditions for different train types and operating environments. The system accurately evaluates key performance indicators such as friction coefficient stability, wear rate, thermal stability, and braking consistency, ensuring product reliability in real-world operation.

Q4: Do you support customized railway brake pad solutions?

A: Yes. With strong R&D capabilities and advanced testing facilities, we provide customized friction material solutions based on different train models, operating conditions, and regional requirements. Our products can be tailored for high-speed rail, freight trains, metro systems, and other rail transit applications.

Q5: What are your railway brake products mainly used for?

A: Our railway brake pads are widely used in high-speed trains, locomotives, freight wagons, passenger coaches, metro systems, urban rail transit, and heavy-duty railway maintenance equipment. They are designed to meet braking requirements across different speeds, loads, and complex operating environments.

Q6: How is the service life and replacement cycle of railway brake pads determined?

A: The service life of railway brake pads is determined according to different operators’ wear limit standards and technical specifications. During operation, wear conditions are continuously monitored. Once the brake pads reach the defined wear limit set by railway operators or vehicle manufacturers, they must be replaced to ensure safe and stable braking performance under all operating conditions.

Q7: Do your products have international railway certifications?

A: Yes. We hold multiple internationally recognized railway certifications, including CRCC (China), UIC (Europe), GOST (Russia), and IRIS (International Railway Industry Standard).
