Core principles for material selection
Core principles for material selection
| Material Type | Friction Coefficient Stability | Temperature Resistance Limit (°C) | Environmental Friendliness | Noise Level | Cost Grade |
|---|---|---|---|---|---|
| Semi-metallic Liner | Moderate | 400-500 | Average | Relatively High | Low |
| NAO Liner | Good | 350-450 | Good | Low | Medium |
| Ceramic Liner | Excellent | 600-850 | Excellent | Extremely Low | High |
| Copper-free Environmental Liner | Good | 400-550 | Excellent | Low | Medium-High |
III. Core Principles for Material Selection
Selection based on operating temperature:
For low temperatures (-40°C to 200°C), choose semi-metallic liners or copper-free liners.
For high temperatures (above 200°C), choose ceramic liners.
Selection based on environmental requirements:
For export or new energy scenarios, prioritize copper-free liners or ceramic liners.
For ordinary fuel vehicles, NAO liners or semi-metallic liners are optional.
Selection based on cost budget:
For cost-effectiveness needs, choose semi-metallic liners.
For comfort needs, choose NAO liners.
For high-end performance needs, choose ceramic liners.
Notes on Key Terminology Translation
NAO 衬片: Abbreviation for "Non-Asbestos Organic Liner" (non-asbestos organic liner), commonly referred to as "NAO Liner" in the automotive braking industry for conciseness.
无铜环保衬片: Translated as "Copper-free Environmental Liner" to accurately reflect the two core attributes (copper-free composition and environmental friendliness) while conforming to industry expression habits.
成本等级 (Cost Grade): Classified into "Low", "Medium", "Medium-High", and "High" to maintain the original data's comparative logic and ensure clarity in English.
