We are extremely quality-conscious because we are fully aware that if 'DIACH' is to become a world leader we should produce our best. Our highly committees and motivated team is constantly engaged in trying to see that no compromises are made with the qualityof any specificationof the product...
Summary of properties of lead-free solder alloys What is lead-free solder? Lead-free solder (PB-free solder) means that the chemical composition of the solder does not contain lead (Pb), and the Rohs directive requires that the Pb content does not exceed 1000PPM or 0.1%. The main represe...

The mechanical properties of ternary lead-antimony-magnesium alloys are substantially improved relative to those corresponding to binary lead-antimony alloys. The following table shows, by way of example, the variation of hardness and braking load as a function of composition for some alloys: ...
In this paper, a detailed study of the effect of small composition changes (major additions) and of micro additions is presented. Improvements in thermal, mechanical and metallurgical properties of the new alloys are discussed and compared to Sn-Ag3-Cu0.5. We show that the newly developed Pb-...

(1966)were the first to report a systematic difference between the isotopic composition of lead in bulk rocks compared to that released from the same rocks by weathering. The behavior of lead isotopes during rock and mineral weathering was further studied byErelet al.(1994)andHarlavanet al.(...
