Yellow metal fasteners are used in applications where excellent corrosion resistance, non-magnetic properties, and aesthetic appeal are important. Commonly manufactured from materials such as Brass, Bronze, or Copper Alloys, these fasteners are ideal for use in marine environments, electrical installations and instrumentation.
Their resistance to seawater and many chemical solutions makes them particularly suitable for shipbuilding, valve assemblies, and pump components. Additionally, their non-sparking and conductive properties make them valuable in industries such as oil and gas, electrical engineering, and hazardous environments where safety and reliability are paramount.
Copper, Brass & Nickel Aluminium Bronze Grades
NES 833
Nickel Aluminium Bronze; high strength and excellent corrosion resistance in seawater and marine atmospheres, ideal for naval and offshore applications.
NES 834
Nickel Aluminium Bronze; improved mechanical properties and resistance to cavitation and erosion, suitable for high-performance marine components.
DGS 1043
Nickel Aluminium Bronze; used for fasteners and components in highly corrosive environments, offering excellent resistance to biofouling.
DGS 1044
Nickel Aluminium Bronze; similar to DGS 1043 but with enhanced ductility and toughness for demanding marine and hydraulic applications.
