High-leaded tin bronze UNS C93200 is a cast alloy of copper-tin-lead. The addition of nickel in the alloy improves the strength and ductility.
Copper alloys are available in more than 400 varieties. Each copper alloy variety has specific properties that suit a number of manufacturing processes, environments and applications.
Pure copper has high electrical and thermal conductivity. Alloys can be freely formed by the copper. The UNS 11300 silver-bearing tough Pitch copper has 101% IACS conductivity, and high ductility. It is available in the form of wire, rod, and tube.
Leaded nickel-tin bronze UNS C93400 is a cast alloy of copper-tin-lead. The addition of nickel in the alloy enhances the strength and ductility.
Copper alloys are available in more than 400 varieties. Each copper alloy variety has specific properties that suit a number of manufacturing processes, environments and applications.
Brass-copper alloy UNS C43400 has excellent cold working properties making it ideal for machining. High thermal conductivity enables the UNS C43400 to be used in heat exchangers.
UNS C17000 beryllium copper alloys are ductile, heat treatable and can be mill hardened. These alloys are used in applications, which require high strength and good conductivity. The following section will discuss in detail about UNS C17000 beryllium copper alloys.
Cold-work tool steels include the high-carbon, high-chromium steels or group D steels. These steels are designated as group D steels and consist of D2, D3, D4, D5, and D7 steels. These steels contain 1.5 to 2.35% of carbon and 12% of chromium.
Copper-nickel alloys have excellent resistance to biofouling and marine corrosion, and possess good fabricability. Copper gains more strength and corrosion resistance when nickel is added to it.
This article explores the materials and design possibilities of the technology, and the impacts it might have on industry.
