respect the European and world directives and laws, it is necessary to reduce a quantity
of toxic element and to establish lead and cadmium free solders in production. In this
paper it was presented lead-free alloys, which are used for ecological solders
manufacturing and various applications. These are results in the frame of technology
development project no. 19011 titled: “Developing of Technology and Ecological
Solders Production” have done for Serbian Ministry for Science and Technological
