Mechanical Properties of Deposited Metal
Tensile strength: 260~340 MPa
Elongation: 20~25 %
Brinell Hardness: 75~90 HB
Features
· Tin alloy improves weld wear resistance & corrosion resistance; phosphorus acts as deoxidizer for cleaner weld.
· Good fluidity, excellent wetting, easy operation for bronze casting repair.
· Color matching well with tin bronze / phosphor bronze base material. ⚠️ Wider crystallization temperature range brings slight hot cracking tendency; keep small weld pool & shorten welding time.
Application
Welding tin bronze, phosphor bronze, brass castings
Welding brass to steel, copper alloy casting repair
Surfacing low-load wear parts: bushings, bearings, valve components
Can weld pure copper (acceptable tin content in weld metal)
