Copper Alloy Ingots & Billets

Brass Ingots & Billets

Brass is an alloy made of copper and zinc; the proportions of zinc and copper can be varied to create a range of brasses with varying properties. It is a substitutional alloy: atoms of the two constituents may replace each other within the same crystal structure. Brass is used for decoration for its bright gold-like appearance; for applications where low friction is required such as locks, gears, bearings, doorknobs, ammunition casings

and valves; for plumbing and electrical applications; and extensively in brass musical instruments such as horns and bells where a combination of high workability (historically with hand tools) and durability is desired. It is also used in zippers. Brass is often used in situations in which it is important that sparks not be struck, such as in fittings and tools around explosive gases.

Silicon Brass Ingots & Billets

Silicon brass are part of the subgroup of high strength brasses. These materials contain less than 20% zinc and less than 6% silicon. The silicon brasses are solid solution strengthened. These silicon brasses are typically chosen because of their high strength and moderately high corrosion resistance. The conductivity of the silicon brasses is much less than that of unalloyed copper. The silicon red brasses are used for valve stems

where corrosion and high strength are critical. The wrought silicon red brasses are designated as UNS C69400 through C69710. Included in this category are the silicon red bronzes. These alloys are similar to the silicon red brasses except they contain very low concentrations of zinc. The silicon red bronze alloys are designated UNS C47000 through C66100. The cast silicon red brasses are C87300 to C87900. Silicon brass castings exhibit moderate strength and very good aqueous and atmospheric corrosion resistance. They are used in applications such as bearings, gears, and intricately shaped pump and valve components.

High Tensile Brass Ingots & Billets

CW721R / CZ114 is a high tensile brass consisting of a duplex structure. Developed for more exacting applications where strength and corrosion resistance are required. Also referred to as a manganese bronze the CW721R / CZ114 has additions of aluminium, iron, tin and manganese that are added to the basic 60/40 brass matrix, creating a variety of properties to benefit the designer.

The aluminium and tin content gives the CW721R / CZ114 a brighter finish and is the main reason for the increase in corrosion resistance. The iron and manganese additions also improve the strength level, with the iron also acting a grain refiner. Some of the other benefits of the CW721R / CZ114 grade are a very good hot working capacity to allow for hot stamping and a good machinability rating.

Silicon Bronze Ingots & Billets

Silicon bronze is a low-lead brass alloy that is generally composed of 96 percent copper. The remainder can be made from silicon and a variety of other alloys such as manganese, tin, iron, or zinc. Silicon Bronze is known for its easy pouring ability, appealing surface finish and superior corrosion resistant properties, even when submerged in liquids and chemicals. Silicon Bronze was originally developed for the chemical industry but

Aluminium Bronze Ingots & Billets

Aluminium bronze is a type of bronze in which aluminium is the main alloying metal added to copper, in contrast to standard bronze (copper and tin) or brass (copper and zinc) . A variety of aluminium bronzes of differing compositions have found industrial use, with most ranging from 5% to 11% aluminium by weight, the remaining mass being copper; other alloying agents such as iron, nickel, manganese, and silicon are also

sometimes added to aluminium bronzes. Aluminium bronzes are most commonly used in applications where their resistance to corrosion makes them preferable to other engineering materials. These applications include plain bearings and landing gear components on aircraft, Ernie Ball Aluminum Bronze strings, engine components (especially for seagoing ships), underwater fastenings in naval architecture, and ship propellers.
