This diagram shows a pumping phenomenon of tin phases ⁇ , ⁇ 'by the ⁇ phase.
FIG. 3 is a photograph intended to highlight the hot malleability of the alloys according to the invention (alloys 2 and 4) by crushing tests of 55% (upper pions) and 80% (lower pions), carried out at 700, 750 and 825 ° C.
FIG. 4 is a diagram showing a section of a coin stamped according to the invention in contact with water, explanation of the mechanism of accelerating action of arsenic on the release rate of lead in drinking water
FIG. 5 is a diagram which shows the elements of the photograph of FIG.
the tin content of the CuZnPbSn alloy can be between 1.4 and 1.6%.
the lead content can be between 1.9 and 2.1%.
the iron content may be less than or equal to 0.2%.
the arsenic content can be between 5 and 500 ppm.
the aluminum content can be between 5 and 500 ppm.
the antimony content can be between 5 and 100ppm.
the silicon content may be between 5 and 500 ppm.
Another subject of the invention comprises the semi-products obtained from the CuZnPbSn alloy according to the invention, in which the microstructure of the alloy is composed of three intermetallic phases: ⁇ , ⁇ 'and ⁇ .
said CuZnPbSn alloy may have a composition chosen so that, according to ISO 6509, said semi-product obtained from this alloy has a mean dezincification depth of less than 200 ⁇ m, and even typically less than 150 ⁇ m, so that said alloy CuZnPbSn, which is not arsenic, is much higher than the CW617N alloy and even approaches the performance of the arsenic alloy CW602N .
said CuZnPbSn alloy may have a composition chosen so that the semi-product obtained from this alloy has, for a drilling operation performed under the usual machining conditions. according to standard NF E66-520-7 of the 2000 edition, an average chip size typically two times smaller than that obtained with the CW602N alloy which is a brass with arsenic.
said CuZnPbSn alloy may have a composition chosen so that the hot-pressing test according to the ASTM E209-00 standard of the 2000 edition. , and made in the range of 600 ° C to 750 ° C, causes no cracking of said half-product obtained from this alloy.
the semi-finished products according to the invention have a large latitude of hot deformation, as regards both the temperature range and the crushing rate, without the appearance of cracks or cracks in the metal.
These semi-finished products a great ability to deform without cracking or cracks, which is extremely advantageous in practice.
said CuZnPbSn alloy of said half-product may have a composition chosen so that the release rate of lead in drinking water is below the regulatory threshold according to European Directive 98 / 83 / EC on the quality of water intended for human consumption. It is important to note also the very low rate of Zn release compared to that of alloys Nos. 5 and 6.
said CuZnPbSn alloy may have a composition chosen so that said half-product has a high heat malleability, and so that its crush resistance is lower. to that obtained with the CW602N alloy, and preferably two times less than that of said CW602N alloy. It goes without saying that the power installed on the machines or devices for manufacturing the finished products, in particular when such manufacture comprises deformation of the half-product by crushing, will be less in the case of the semi-finished products according to the invention than in the case of the semi-finished products of the state of the art formed from alloys Nos. 5 and 6.
Another object of the invention is formed by the finished product obtained from the semi-finished product according to the invention, the half-product being typically chosen from: a tap, a valve, a coupling.
Another object of the invention is formed by the process for manufacturing the finished product according to the invention, in which process said finished product is typically formed by deformation or machining of said semi-finished product, said process not comprising a treatment step thermal, which is very advantageous and economical in practice compared to comparable processes of the state of the art.
Another object of the invention is formed by the use of a CuZnPbSn alloy according to the invention, or a semi-finished product according to the invention or obtained according to the invention, for the manufacture of finished products or used components. for sanitary water distribution such as valves, valves and fittings.
