Definitions

the present invention relates to brass compositions with extremely low to no lead content.
the compositions exhibit good machinability and strength similar to that of conventional leaded brass alloy free machining brass.
the lead phase in copper lead alloys can be affected by corrosive attacks with hot organic or mineral oil.
hot organic or mineral oil For example, when temperature of such an alloy rises, it has been known that the oil can break down to form peroxides and organic gases which effect a degree of leaching on the lead phase within the alloy. If this leaching progresses to any appreciable extent, the component, if it is a bearing or structural component, may eventually malfunction or fail.
the present invention relates to a brass alloy consisting of: copper, from 2% to less than 15% zinc, from 0.4% to 1.0% tellurium, less than 0.25% lead, and optionally less than 0.02% phosphorus.
the alloy typically has a lead content of from less than 0.025% to less than 0.001% which is considered “lead-free.”
the alloy exhibits excellent machinability and conductivity. Depending on the composition of the alloy, the tensile strength will vary between 240 MPa and 530 MPa and yield strength will vary from 200 to 450 MPa. Conductivity will range from 28% to 49% IACS.
the machinability of the novel alloy of the invention is similar to that for lead containing compositions. This eliminates or reduces the amount of retooling needed to use the novel alloys to produce finished products such as plumbing fixtures.
the brass alloys of the present invention are prepared by first melting copper at a temperature of about 1050°C. Zinc and tellurium are then added to the molten copper. Brass alloy is then cast into billets utilizing horizontal or vertical casting methods.
the copper used to make the alloys is typically copper cathode or high grade uncontaminated and pure copper scrap comprising 99.95% minimum copper and to .05% impurities.
Lead is a typical impurity, comprising less than 0.025% of the copper used.
Zinc is the next major component comprising from 2% to less than 15% of the alloy.
Tellurium is used as a replacement for lead. Like lead, tellurium is added to improve machinability of the alloy without the negative contribution of lead. Tellurium is added in an amount ranging from 0.4% to 1.0%. In one embodiment, tellurium comprises about .5% of the alloy. The amount of tellurium used will depend, in part, on the amount of copper used in the alloy, as copper levels increase the amount of tellurium used with decrease. Like lead, the addition of tellurium to the alloy creates discontinuities in the copper and zinc phases of the alloy like those shown in Figs 1-3 . The good dispersion of these discontinuities leads to the improved machinability of the alloys.
One advantage of the present invention is that the alloys exhibit machinability similar to that of lead containing alloys while using significantly lower amounts of tellurium.
phosphorous When phosphorous is used, the amount present will typically be less than 0.02% of the alloy.
the resulting alloys will generally exhibit excellent machinability and conductivity as indicated by Ultimate Tensile Strength (UTS) ranging from 240 to 530 MPa and a yield strength of from 200 MPa to 450 MPa as determined using ASTM method B140.
UTS Ultimate Tensile Strength
the actual Tensile strength and Yield strength will depend, in part, on the actual composition of the alloy.
Conductivity of the alloys will range from 28 to 45% IACS.
the billets were then changed into an extrusion press at a temperature ranging from about 780°C to about 860°C.
the billets were then hot extruded through a variety of dies and at different pressures to produce numerous sizes. Each shot was lubricated prior to extrusion and the extrusion dies were preheated. The results are shown in Table 2.
Conductivity tests were then conducted on various samples. Conductivity diminishes as the ratio of zinc content increases. The results ranged from at least about 28% to about 49% maximum.
FIGS 1-3 Photomicrographs of Samples C1, C2 and C3 were taken after draw and are shown in FIGS 1-3 .
the micro structure in the alloys were uniform indicating good dispersion of the tellurium throughout the alloy.
