Purpose: The purpose of the test was to specify influence of re-fusions of the nickelchromium prosthetic alloy Ducinox on its strength properties. Design/methodology/approach: The tests were carried out on the samples cast of the Ducinox alloy molten once, twice and three times. The hardness has been measured using the Vickers method; the tensile strength has been also specified. The samples designed for strength tests were subjected to X-ray control to find possible defects that would eliminate the samples from further tests. The last test was observation of fractures occurred as a result of the strength tests, under the microscope. Findings: Both hardness measurements and strength tests did not show statistically significant differences among individual groups of samples. Practical implications: Based on the results of the tests carried out, it can be found that re-fusion of the alloy Ducinox has no influence on its tensile strength. Thereby, in the dental technology practice, it is possible to add the casting scrap to pure metallic alloy without influence on strength of prosthetic element castings. Originality/value: This is an well-known method of analysis which is applied in many scientific fields. However in modern prosthetics it is new approach.
