■ Key Characteristics & Industrial Applications
Silicon Bronze C65800 combines high mechanical strength with outstanding corrosion resistance, making it a trusted alternative to stainless steel in the most demanding marine, chemical, and electrical environments.
- Corrosion Resistance: Highly resistant to saltwater, brine, and various chemicals, outperforming standard brass and even some stainless grades in anoxic marine conditions.
- Anti-Galling Properties: Unlike stainless steel, silicon bronze fasteners are highly resistant to thread galling (cold welding) during installation under heavy loads.
- Non-Magnetic & Conductive: Ideal for electrical applications and switchgear where magnetic interference must be avoided and conductivity is preferred.
- Aesthetics: Develops a rich, protective patina over time, making it highly desirable in architectural applications, boat restoration, and outdoor wood construction.
■ Primary Industries Served
- Marine: Shipbuilding, dock construction, and below-waterline hardware.
- Power Generation: Switchgear, grounding hardware, and electrical connections requiring non-magnetic properties.
- Waterworks & Plumbing: Water treatment facilities, valve and pump assemblies.
- Chemical Processing: Fastening solutions for equipment exposed to corrosive process chemicals.
