CuSn9P Thermal Spray Wire | High-Tin Phosphor Bronze Wire for Superior Wear & Corrosion Protection
Product Description
CuSn9P thermal spray wire is a high-tin phosphor bronze alloy wire containing approximately 9% tin and phosphorus, specifically designed for thermal spraying to produce dense, highly wear-resistant coatings with excellent corrosion resistance. Compared with CuSn8P, CuSn9P offers significantly higher hardness, superior mechanical strength, and enhanced resistance to fatigue and galling, making it ideal for demanding industrial applications where maximum durability is required. It is suitable for both arc spray and flame spray processes, delivering uniform coatings with strong adhesion for critical surface protection and dimensional restoration.
Key Features
- High-tin phosphor bronze alloy (CuSn9P) with superior wear resistance
- Excellent corrosion resistance in marine and industrial environments
- Higher hardness and tensile strength than standard bronze alloys
- Strong adhesion and uniform coating structure
- Suitable for arc spray and flame spray processes
- Stable wire feeding and consistent coating quality
