It is possible to produce low-titanium aluminum alloy directly. Three months of periods of industrial test for production low-titanium aluminum alloy was conducted using the 80kA prebake electrolysis cells. The test results showed that the electrolysis cell can work stably, and the effect of TiO2 added into electrolyte on electrolytic process parameters, current efficiency, consumes of materials and energyare trifling. The titanium content in alloys is stable and the absorbility of Ti is high. The microstructure of electrolytic low-titanium aluminum alloy is homogeneous. The grain refinement effect is excellent comparing with that of alloys added titanium by melting Al-Ti master alloys and both alloys have the same grain refinement trend.

The second consideration is properly connecting the ends of the aluminum magnet wire. The reason for this goes back to your high school chemistry course. You may remember that aluminum oxidizes much faster than other metals—in fact, if exposed to air, powdered aluminum will completely oxidize in a few days, forming a fine white powder.

To correct the variation resulting from exposure condition, an aluminum stepwedge was exposed simultaneously. By referring the image of aluminum stepwedge on each radiograph the equivalent aluminum thickness and corrected gray level intensity of the ROIs could be calculated as indicators of alveolar bone density. Nineteen specimens containing different amounts of hydroxy-phosphorite were radiographed.
