Definitions
- the present invention relates to zinc alloys for zinc casting or zinc die casting containing, besides zinc and the inevitable impurities contained therein, from 0.1 to 6% by weight of aluminum, from 0.01 to 1.5% by weight of copper, from 0.001 to 0.06% by weight % Of magnesium and 0.001 to 0.2% by weight, preferably 0.002 to 0.06% by weight of silicon.
- Some of these zinc alloys are commercial fine zinc alloys that are manufactured and marketed under the trademark ZAMAK®. In particular, it is the alloys ZL 0410 (ZL5), ZL 0400 (ZL3), ZL 0210 (not standardized) and the alloy ZL 0010 (ZL16).
- the standards of alloys ZL5, ZL3 and ZL16 comply with DIN EN1774.
- the composition is summarized in the following table: ZL 0410 ZL 0400 ZL 0210 ZL 0010 (ZL5) (ZL3) (not standardized) (ZL16) al 3.8 - 4.2 3.8 - 4.2 1.8 - 2.2 0.01-0.04 Cu 0.7 - 1.1 0.03 max.
- Grain refining is of considerable importance for zinc die casting in particular.
- titanium and boron can be used as grain refiner titanium and boron.
- the titanium and / or boron is preferably added in the form of a master alloy with aluminum.
- master alloys are known as AlTi5B1, AlTi3B1 and / or AlTi5B0.5.
- the object of the invention has been found to improve the behavior of zinc alloys in zinc casting and in particular in zinc die-casting.
- the grain refining according to the invention achieves the following improvements in particular for die-cast components: the ductility, the creep rupture strength, the tightness, the mold filling behavior in the die-casting process, and the surface quality. Finally, a significant reduction of reject components is achieved.
- a further advantage of the alloy according to the invention is that even amounts as small as 0.001 to 0.2% by weight, preferably 0.002 to 0.06% by weight, of silicon improve the properties. It is therefore possible to use aluminum in a purity level of 99.7 (0.2 wt% silicon). A Alloy with 4% by weight of such aluminum automatically results in a content of about 80 ppm of silicon in the final alloy.
- the die-cast alloys ZAMAK® ZL 0410, ZL 0400, ZL 0430, ZL 0210 and the alloy ZL 0010 were alloyed with the master alloy AlTi5B1.
- AlTi5B1 per ton of zinc alloy was added.
- the boron content was about 10 ppm and the titanium content about 50 ppm.
- 200 ppm silicon was added.
- Masses were poured off. These pigs were remelted, and the flow behavior was determined with a special mold. The discharge length was measured. Thereafter, the fluidity increases by 10 to 20%.
- the new alloys were processed on a die-casting machine into components. Tensile samples were taken from these components. It was found that the tensile strength of the new alloys was more than 10% higher than for comparative samples without the addition of the alloy.
