BAg-5 Type(Ag-Cu-Zn 3 Elements)
BAg-4 Type(Ag-Cu-Zn-Ni 4 Elements)
BAg-7 Type(Ag-Cu-Zn-Sn 4 Elements)
5 Elements(Ag-Cu-Zn-In-Mn)
It has been widely used in each industry as well electronics that BAg-1, BAg-1A,
BAg-2 and BAg-3 out of 10 types internationally standardized Silver Filler Metals,
but it contains much amount of cadmium (Cd) of 15~20%.
Therefore our reseachers developed Cd-Free Silver Filler Metal more safe and
excellent than existing one to solve safety problems caused by heavy metal
cadmium pollution.

Characteristics of
Cd-Free filler
1) It is fee of Cd, replacing the fluidity of Cd with those of In, Sn to provide low melting point and rich flow (fluidity) and corrosion resistance.
2) As it has tendency not to be melted if heating slowly at the above-shown melting point range, it is recommended to heat quickly.
