Free-machining brass contains about 58% copper and 39% zinc. Lead is added to improve machinability, in content of 1-3%wt. The microstructure is constituted by two phases, α and β. Duplex brass is easier to be hot worked by extrusion or stamping and machine.   Generally, an increase of Zn content produces stronger alloys with a moderate decrease in corrosion resistance and cold ductility. Other alloys required to be free-machining , yet retaining sufficient ductility for riveting or other cold work, contain less lead and more copper.   Halcor can produce Leaded Brass Rods, Flat Bars, Sections and Wires.  PropertiesLead isn’t soluble in a copper matrix and for that reason lead is dispersed homogenously in the form of fine globules in the microstructure. Lead acts as a lubricant decreasing the friction coefficient between the tool and the material, creating discontinuities that promote the chip fragmentation, reducing the cutting force and the tool wear rate.   Additions of other elements such as manganese, tin, aluminum, iron, silicon and arsenic may be used to improve strength and corrosion resistance. Leaded brass is used for its excellent machinability, good strength and atmospheric corrosion resistance.ApplicationsLeaded brass is used for architectural hardware, general purpose screw machine parts, screws, valves, fittings, bearings and specialty fasteners.Material Designation

Single phase alpha brass is characterized by maximum cold ductility and can be extensively deformed by rolling, drawing, bending, spinning, deep drawing (for the manufacture of cartridge cases), coining, piercing, cold heading and thread rolling. Tubes for heat exchangers are frequently manufactured from the alpha brass, normally of 70/30 composition but often containing alloying additions which enhance corrosion resistance. Substantial quantities of alpha alloys are also used for the manufacture of fasteners such as wood screws, rivets and zip fasteners. For less demanding fabrications such as spring contacts in a domestic electrical socket, an alloy with a higher zinc content can be used, such as CuZn33, CuZn36 and CuZn37 (common brass). These alloys are not quite as ductile as CuZn30, although other mechanical properties are similar.   Halcor can produce lead free brass Solid Rods, Seamless Βrass Tubes, Welded Brass Tubes, Flat BarsSections and Wires.    Material Designation

High Tensile brass is copper-zinc alloy which combines with additives to increase the tensile strength over that of the simple binary copper-zinc brass.   Halcor can produce High Tensile Brass Solid and Hollow rods.PropertiesThis family of alloys exhibit tensile strength in excess of 700N/mm2, along with enhanced properties of wear and corrosion resistance.   The alloys containing aluminium have an attractive, naturally lustrous surface and a protective oxide film for extra corrosion resistance. The silicon-containing alloys with manganese have excellent wear resistance, due to the formation of a very hard intermetallic compound, manganese silicide, in the basic matrix.ΑpplicationsThey are suitable for a wide range of applications and service conditions, ranging from decorative architectural use to wear resistant automobile transmission components and the high strength, high integrity equipment used in mines.  EU End of Life Vehicle (ELV) DirectiveThe EU End of Life Vehicle (ELV) Directive, adopted in September 2000, includes provision for phasing out metals such as lead used in automotive components. Applications for these copper alloys include bearing shells and bushes, nozzles, connection parts, fixtures and locks.Material Designation

DZR (Dezincification-resistant) brass constitutes the best solution for use in unusually aggressive water supplies. In this environment, conventional duplex brass water fittings can suffer, a form of corrosion known as dezincification. This involves selective leaching of the zinc which can cause fracture of the fitting. Addition of a small amount of phosphorous, arsenic or antimony inhibits the occurrence of the dezincification.   Halcor can produce DZR Solid and Hollow Rods and Seamless Tubes.PropertiesBrass at hot stamping or extrusion temperature, contains sufficient β phase to be hot-worked satisfactorily.The B phase can be converted by subsequent heat treatment to an all-alpha structure which is protected against dezincification by incorporating arsenic in the alloy. Forgeable DZR brass, such as CW602N (CZ132), is leaded brass and its machinability is comparable with the leaded duplex brass CW617N (CZ122). They are commonly used for production of water fittings. Rods and bars for machining are heat treated by the materials supplier to put them into the dezincification-resistant condition. Forging stock is supplied without heat treatment since it must be heated after forging to 500-525ºC, held for at least two hours and slowly cooled, to ensure resistance to dezincification. This has to be done by the fittings manufacturer. The need for heat-treatment after forging, to ensure an all-alpha structure, can sometimes be avoided by controlled slow cooling through the temperature range 550ºC to 450ºC. Although, this is a more difficult method to achieve the correct degree of dezincification resistance.ApplicationsThese alloys are used as fittings, stopcocks and valves with a carefully controlled composition, which are made by extrusion or hot stamping. This production process must be followed by heat treatment to ensure that the material will satisfy the requirements of the standard dezincification-resistance test (EN ISO 6509-1). The maximum permitted parameters of dezincification are defined in EN product standards.Material Designation

Naval Brass has a chemical composition of around 60% copper 39% zinc and 1% tin with an amount of lead. These alloys are included in the family of α and β or duplex brass. This category of brass exhibit generally higher mechanical properties than other non-duplex brass.   Halcor can produce Naval brass Solid and Hollow rods and Sections.PropertiesAs its name implies, naval brass is widely used for naval and steam-generating equipment and generally for sea water service applications, where a strong, hard material is required. Tin is included in the alloy composition in order to improve the corrosion resistance of the material. Tin tends to inhibit dezincification. Dezincification is a type of dealloying in which one of constitutes of an alloy is removed by corrosion. In this case, Zn is depleted and results in a porous Cu-rich layer. The presence of lead in naval brass assists in the machinability of the metal. This subcategory of brass is named leaded naval brass and contains nominally 60% Cu, 1% Sn, 2% Pb and 37%Zn. These alloys have the equivalent strength and corrosion resistance of naval brass plus considerably improved machinability.ApplicationsNaval brass is used in propeller shafts, marine hardware, decorative fittings, shafting, propeller shafts and turn buckles. There are also many industrial applications, such as welding rods, condenser plates, structural uses, valve stems, balls, heat exchanger tubes, aircraft turnbuckle barrels, dies, and many more.Material Designation

Evolving beyond copper: The storyline behind HALCOR’s new tagline.


For the past 85 years, HALCOR has been synonymous with copper, internationally. For the company, copper is not simply a raw material; it is the driving force that makes it move forward; that has brought it to the point where it is today and has established it as one of the leading producers of copper & copper alloys in Europe.


Today Halcor is continuing to evolve and is accelerating its growth.


That’s how its new tagline, “Evolving beyond copper” came up. A key message aimed at both the Greek and global market, which suggests that HALCOR evolves copper, brass, and other copper alloys, while at the same time it evolves as an organization as well.

What does “Evolving beyond copper” mean

The notion of the evolution of copper does not refer merely to the new, pioneering alloys of the company. It’s about something bigger and wider than the features of its products; it’s about its vision and tomorrow’s HALCOR.

“Evolving beyond copper” is about a company that invests in ultramodern production units, increasing its yield, and thus holding the leading position in the production of copper tubes in EMEA. That is utilizing high-tech infrastructures created after significant investment, such as the tube heat transfer laboratory, to develop solutions adapted to the needs of its customers. That is becoming, though its advanced offering, a valuable ally to its customers, building long-term relationships that ensure its future growth.

“Evolving beyond copper” is about a company that looks ahead; creates the products of tomorrow; invests in research; invents innovative solutions; supports international sectors, such as HVAC, allowing them to further develop.

“Evolving beyond copper” is about a company that introduces new services in the industrial world; stands out for its unbeatable after-sales service; is recognized as a one-stop-shop that offers the widest range of sharply specialized services; relies on its own strength and is thus able to handle any requirement by any customer.

And, of course, “Evolving beyond copper” is about a responsible company, that is acting towards a sustainable future for all.

All this – and even more – is the meaning of HALCOR’s new message, today. And it will undoubtedly encapsulate more meanings in the future. Because HALCOR is one, forward-looking, ceaselessly evolving team. A team now equipped with the tagline that reflects its creative restlessness and its need to constantly become better.
