Cast Copper Alloy Products
Copper and copper alloys are some of the most versatile engineering materials available. The combination of physical properties such as strength, conductivity, corrosion resistance, machinability and ductility make Copper suitable for a huge range of applications. With their properties being further enhanced by variations in composition and manufacturing methods.
There are pushing 400 commercial compositions for Copper alloys. The most often in use at Archibald Young tend to be in the Bronze classifications (Aluminium, Phosphor and Gunmetals) although Brass and CuproNickel alloys are not uncommon either.
Copper and Copper alloys can be used in an extraordinary range of our customer applications including:
- Architectural applications
- Electrical cabling
- Pump and valve applications
- Marine engineering parts
- Heat exchangers
In addition, there are so many more applications.
Copper alloys are highly suited to recycling with around 40% of the annual consumption of Copper alloys being derived from recycled Copper materials. The vast majority of Copper based alloy ingot material going through our production here is derived from secondary smelting of recycled materials.
Copper is a tough, ductile and malleable material which makes copper extremely suitable for sand casting into a variety of shapes and forms to suit our customer applications. In most marine and industrial atmospheres Copper alloys are resistant to corrosion with Copper itself being resistant to saline solutions, soils, non-oxidising minerals, organic acids and caustic solutions. The corrosion resistance of Copper alloys comes from the formation of adherent films on the material surface. These films are relatively impervious to corrosion therefore protecting the base metal from further attack. Copper Nickel alloys, Brass and Aluminium Bronzes demonstrate even greater resistance to saltwater corrosion.
Most Copper alloys will develop a blue-green patina (Verdigris) when exposed to the elements with some alloys further darkening after prolonged exposure to take on a brown to black colour. In our artistic and architectural castings these patinas can be artificially replicated to give an aged appearance to a new product.
