Hemispherically tipped riders of aluminum bronze and the titanium and copper alloys were run against Ti6Al4V disks in air at 430 C. The sliding velocity was 13 cm/s, and the load was 250 g. Results revealed that hightincontent titanium and copper alloys underwent significantly less wear and galling than commonly used aluminum bronzes....
Difference Between Steel and Titanium | Difference Between
Certain claims by marketing associates and companies gave way for the controversy to rise that titanium is stronger than steel, but unlike the claim, the best steel is stronger than titanium alloys. In unalloyed condition, titanium is 45% lighter, and as strong as steel. We can presume that the same rod of steel will be 5% stronger than ......
