CuSi3Mn1 Thermal Spray Wire - Wear Resistant & Corrosion Resistant Silicon Bronze Spray Wire with Customizable Diameter

Product Description

CuSi3Mn1 thermal spray wire is a silicon bronze alloy wire containing approximately 3% silicon and 1% manganese, designed for thermal spraying to produce wear-resistant and corrosion-resistant coatings. Compared with pure copper coatings, CuSi3Mn1 provides higher strength, better hardness, and improved resistance to abrasion while maintaining good corrosion resistance.
It is suitable for arc spray and flame spray processes, producing uniform coatings with good adhesion for surface protection and dimensional restoration.
