Definitions
- the present invention concerns an essentially arsenic-free brass alloy with improved dezincification resistance, protection against intergranular grain boundary corrosion, and machinability.
- Brass is a material the basic components of which are copper (Cu) and zinc (Zn).
- alloying materials such as lead (Pb), iron (Fe), aluminium (Al), nickel (Ni), manganese (Mn), silicon (Si)
- the brass can be given unique properties, and there are many different brass alloys adapted to different types of processing and final products.
- the brass will consist of different so-called phases, which are microstructure components.
- the usual phases of brass are the ⁇ -phase, which is rich in copper and the ⁇ -phase, which is rich in zinc. Often, brass consists of a mixture of these two phases.
- a solid solution having a uniform brass composition is formed when up to about 35 % by weight of zinc is added to copper.
- a further increase of the content of zinc gives a mixture of the original solid solution (the ⁇ -phase) and a new solid solution having a higher content of zinc (the ⁇ -phase).
- Brass containing between 35-45 % by weight of zinc consists of mixtures of these two phases and is called ⁇ - ⁇ -brass or duplex brass, the relationship between the ⁇ -phase to the ⁇ -phase depending primarily on the content of zinc.
- the presence of ⁇ -phase in ⁇ - ⁇ -brass gives a decreased cold ductility but a considerably increased susceptibility to hot working by extrusion or punching and casting without thermal cracks, also when lead is present.
- ⁇ - ⁇ -alloys have better mechanical properties and, since they contain a higher share of zinc, they are in certain cases more inexpensive than ⁇ -brass.
- ⁇ - ⁇ -brass alloys have a higher sensitivity to dezincification. Thereby, there is a need of producing ⁇ - ⁇ -brass alloys with dezincification resistance.
- Dezincification is a type of corrosion where zinc selectively is attacked and leaves a porous copper structure.
- Dezincification resistant brass has a relatively high Cu content, above 60 %, and contains an inhibitor such arsenic (As), antimony (Sb), or phosphorus (P), which makes the ⁇ -phase of the brass resistant to dezincification. Since only the ⁇ -phase can be stabilized, it is important to minimize the content of ⁇ -phase by a higher content of copper.
- Brass alloys may in addition to dezincification be subjected to intergranular grain boundary corrosion, which is a form of corrosion taking place along the grain boundaries.
- intergranular grain boundary corrosion is a form of corrosion taking place along the grain boundaries.
- the content of zinc is higher at the grain boundaries of brass alloys and intergranular grain boundary corrosion attacks just at the zinc present along the grain boundaries. Thereby, there is also a need of protecting brass alloys against intergranular grain boundary corrosion.
- the American Academy of Sciences has estimated the lifetime risk of cancer to 1-3 cases per 1000 individuals at a daily intake of 1 l of drinking water having arsenic contents at the threshold level of 10 ⁇ g/l, which exceeds the low-risk level (approx. one case per 100 000 exposed) that could be considered to be an acceptable risk of an individual environmental factor [3]. As with other carcinogenic substances, the risk of health effects decreases at decreased exposure.
- the threshold for arsenic in drinking water is 10 ⁇ g/l within the EU.
- the threshold for arsenic in drinking water in Sweden 10 ⁇ g/l, is based on the cancer risk [3].
- Lifetime risk of the genesis of cancer at a daily intake of arsenic corresponding to the threshold in drinking water (10-20 ⁇ g arsenic per day depending on age, climate and physical activity), has been estimated to 1-3 per 1 000 individuals (0.1-0.3 %). Thereby, it is desirable to limit the intake of arsenic as far as possible. This applies particularly to children, since experimental studies show that foetuses and small children are more sensible than adults.
- the object of the present invention is to provide an essentially arsenic-free ⁇ - ⁇ -brass alloy.
- the object is furthermore that the brass alloy has improved dezincification resistance than brass alloys with arsenic or solely arsenic.
- the object is furthermore to provide a brass alloy having similar or better protection against intergranular grain boundary corrosion than brass alloys with arsenic or solely arsenic.

- Said brass alloy is characterized in that it comprises ⁇ 5 % of ⁇ -phase, preferably ⁇ 1 %.

- the chemical composition of 752 is given in Table 1 in % by weight wherein "NBG standard value” indicates the chemical composition of the base alloy desired to be achieved while “Min” and “Max” gives the tolerances.

- Table 1 Minimum, maximum, and standard values for 752 and chemical analysis of the base alloy 752, which was used for the production of the test alloys 1-11. Chemical composition % Min Max NBG std.
- test alloys were produced in the form of ingots of 2 kg by adding As, Sb, and/or P to the base alloy in a furnace (Leybold) where the alloys were melted in a melting-pot (Morgan crucible), which had been placed in an inductance coil. The alloys were melted in the presence of air by means of ventilation above the furnace and the smelt was then poured into a mould by tipping the melting-pot together with the coil. The dimension of the mould was 40 ⁇ 40 mm (height, 300 mm).

Said heat treatment was made at 550 °C for 2 h, and after removal from the furnace, the samples were quickly quenched in water (with a delay of up to 5 min). As has been indicated previously, the purpose of the heat treatment is to reduce the ⁇ -phase in the test alloys.
- the heat treatment was made at 550 °C for 2 h since comparative experiments with other temperatures and time intervals (such as 460 °C to 550 °C for 30 min-8 h) indicate that improved dezincification resistance and protection against intergranular grain boundary corrosion are obtained upon heat treatment at 550 °C for 2 h. Moreover, experiments have shown that heat treatment at 550 °C for 2 h also promotes that the ⁇ -zones are not continuous, which in turn promotes protection against IGA.
