Product Description Introduction to Al-Ti-C Al-Ti-C intermediate alloyOur company has been able to produce Al-Ti-C alloy with good decay resistance and stable product performance. The refining effect is comparable to that of similar products in Europe and America. The alloy composition is basically shaped into three types: Al-5Ti-(0.1~0.5)C, Al-4Ti-(0.1~0.4)C and Al-3Ti-(0.1~0.3)C. After repeated test and comparison, it can be considered that Al-Ti-C alloy can eliminate columnar twins and columnar crystals in aluminum plate and aluminum foil, and ensure dense, fine and uniform grains. It can overcome defects such as cracks, surface peeling, perforation and segregation of aluminum, and significantly improve the strength and toughness of aluminum. Specific performance advantages are as follows:1. Compared with the purity of the intermediate alloy, the Al-Ti-C intermediate alloy is not easy to produce salt inclusion because there is no potassium fluoborate as raw material.2. In the preparation process of Al-Ti-B alloy, TiB2 cluster is easy to form, which cannot be fully diffused after adding melt, or precipitate to the bottom of the flow groove, or exist in the final product to form inclusion, which not only causes thinning decay, but also clogs the filter during continuous thinning of the flow groove, and leads to many defects: For example, axis stripes appear on aluminum printing substrate, perforation appear on aluminum foil, etc. The heterogeneous TiC particles of Al-Ti-C alloy are not only submicron in size, but also dispersed and not easy to aggregate.3. Zr and Cr in some aluminum alloys will cause refining "poisoning" of Al-Ti-B alloys, but not Al-Ti-C alloys.4. The nucleation rate of Al-Ti-C alloy is 5 times that of Al-Ti-B alloy, and the refining effect is remarkable and quick, and the ideal metamorphic effect can be achieved within 2 minutes after adding.5. In terms of the influence of the number of second phase particles, when seeking the same grain thinning effect, Al-Ti-C intermediate alloy can introduce fewer hard points into aluminum melt to avoid the potential adverse effects, overcome the lack of TiB2-containing refiner foil, and improve the quality of the foil.6. It is more advantageous to use Al-Ti-C intermediate alloy to refine grain in the production of boron - free aluminum for nuclear industry.7. When Al-Ti-C alloy is used in the production of A356 aluminum alloy hub, better mechanical properties are obtained than when the best Al-Ti-B alloy is used, and the elongation can be further improved under the premise of good hub deterioration.In addition, the use method of Al-Ti-C alloy (adding amount, adding location, adding temperature, etc.) is not fundamentally different from that of Al-Ti-B alloy. In order to better use Al-Ti-C alloy, it is recommended to reduce the aluminum liquid temperature in the shunt tank or front tank as much as possible. To date, the lowest aluminum melt temperature tested in production is 670 degrees, and there have been no casting problems.In short, the earliest Al-Ti-C alloys are gradually entering the aluminum processing industry with their original and newly discovered advantages. Al-Ti-B and Al-Ti-C alloys can be used by technicians in the aluminum processing industry to further improve the quality of their own products. In the late 1940s, it was found that TiC on aluminum and aluminum alloy solidification grain refining effect, but in the following decades, although people have been committed to generating a stable amount of TiC in aluminum melt and resulting in stable grain refining effect, but has not been successful, this is because there has been no stable production process, Many experimental phenomena have not been fully and deeply analyzed.When it was found that TiC could not be stably synthesized in aluminum melts, the researchers naturally turned their attention to boron B and its compound TiB2, which were next to carbon C in the periodic table. As a result, Al-Ti-B alloy made continuous progress over the next few decades. The synthesis process has been eliminated and is now basically single; After the selection of alloy components, there are basically only three components: Al-5Ti-1B, Al-5Ti-0.2B and Al-3Ti-0.2B. Al-Ti-B alloy produced by a few domestic manufacturers has reached the international first-class level.At the same time, in the past twenty years, Al-Ti-C alloy has also made continuous progress; Thanks to the hard work of researchers, remarkable progress has been made in Al-Ti-C alloys in recent years. Now, the production process of Al-Ti-C alloy has been stabilized, the refining mechanism has been clarified, and the alloy composition is basically settled into three categories: Al-5Ti-(0.1~0.5)C, Al-4Ti-(0.1~0.4)C, Al-3Ti-(0.1~0.3)C. Al-Ti-C alloys developed and produced by a few units in China have reached the leading level of similar Al-Ti-C alloys in the world. After repeated test and comparison, Al-Ti-C alloy can be considered to have at least the following advantages:1. In terms of intermediate alloy production process, Al-Ti-C production process is pollution-free, which is a typical energy-saving and emission-reduction product.2. Compared with the purity of the intermediate alloy, the Al-Ti-C intermediate alloy is not easy to produce salt inclusion because there is no potassium fluoborate or fluorine salt as raw material.3. In terms of grain refining effect, compared with Al-Ti-B, which is the best in the world at present, it has more significant grain refining effect advantage when refining 1070 aluminum or aluminum with higher purity.4. As far as the effect of the number of particles in the second phase is concerned, the potential adverse effect can be avoided by introducing a smaller number of hard points into the aluminum melt through Al-Ti-C intermediate alloys while pursuing the same grain refinement effect, which is more meaningful in the production of PS plates or double-zero foils.5. It is more advantageous to use Al-Ti-C intermediate alloy to refine grain in the production of boron - free aluminum for nuclear industry.In addition, compared with the current best Al-Ti-B worldwide, at reasonable casting temperature, when refining 1000 series, 2000 series, 3000 series, 4000 series, 5000 series, 6000 series, 7000 series, 8000 series alloys, The grain refinement effect of Al-Ti-C intermediate alloy is not inferior to that of the best Al-Ti-B. This is different from what is reported in the general literature.In addition, the use of Al-Ti-C alloy in the production of A356 aluminum alloy hub also achieved better mechanical properties than the use of the best Al-Ti-B alloy (further elongation can be improved under the premise of good hub deterioration, but the degree of improvement varies depending on the shape of the hub).The use method of Al-Ti-C alloy (adding amount, adding position, adding temperature, etc.) is not fundamentally different from that of Al-Ti-B alloy. In order to better use Al-Ti-C alloy, it is recommended to reduce the aluminum liquid temperature in the shunt tank or front tank as much as possible. To date, the lowest aluminum melt temperature tested in production is 670 degrees, and there have been no casting problems.In short, the earliest Al-Ti-C alloys are gradually entering the aluminum processing industry with their original and newly discovered advantages. Al-Ti-B and Al-Ti-C alloys can be used by technicians in the aluminum processing industry to further improve the quality of their own products.
