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.
Key Features

Silicon bronze alloy (CuSi3Mn1) with enhanced wear resistance
-
Good corrosion resistance in industrial and marine environments
-
Higher hardness and strength than pure copper coatings
-
Strong adhesion and uniform coating structure
-
Suitable for arc spray and flame spray processes
-
Stable wire feeding and consistent coating quality
