CuZn40Al2 Self-Lubricating Slide Plates
CuZn40Al2 Self-Lubricating Slide Plates
CuZn40Al2 Self-Lubricating Slide Plates for Cranes
Product Overview
CuZn40Al2 slide plates (CW713R/DIN 2.0550 alloy) are high-strength brass composites with 58.6% Cu, 40% Zn, and 2% Al for enhanced durability. Ideal for self-lubricating slide plates for cranes, they embed graphite or MoS2 solids to minimize friction in heavy-duty linear motion.

Application Scenarios
- 2-Post Hydraulic Lifts: Guide plates prevent side pull and offset for stable vehicle raising.
- Bridge Cranes: Slide plates support high-frequency travel under heavy loads.
- Chain Hoists: Load-bearing supports for construction and logistics, handling impact.
Why Choose CuZn40Al2?
Pain Point Solutions
- High Friction & Side Pull: Stable tribofilm reduces μ to 0.15-0.25, cutting derailment risk by 50%.
- Frequent Maintenance: Lifetime-embedded lubricants eliminate re-greasing, slashing frequency by 70%.
- Corrosion & Deformation: 2% Al passivation + high hardness (HB 120-170) ensures 2+ year life in harsh settings.
Comparison Table: CuZn40Al2 vs. Standard Bronze
| Aspect | CuZn40Al2 Self-Lubricating | Standard Lubricated Bronze | Benefit |
|---|---|---|---|
| Lubrication | Embedded solids (lifetime) | External (monthly) | 70% less maintenance |
| Friction (Dry μ) | <0.2 | 0.3-0.5 | Smoother operation, no stick-slip |
| Tensile Strength | ≥470 MPa | ≤300 MPa | Prevents deformation under 10-ton loads |
| Lifespan | ≥5,000 hours | <1 year | 100%+ extension, 20% TCO savings |
| Cost (Lifecycle) | Lower TCO | Higher due to downtime | ROI via reduced repairs |
