--\nOur eBay Store\n\nR-TECH 856874 Lead-Free Sn-Cu-Ag-Ni-Ge Solder 22SWG 0.7mm 0.5kg\n\nProduct Details\n\nProduced under license from Fuji, this lead-free 5-element solder contains tin (Sn), copper (Cu), silver (Ag), nickel (Ni) and germanium (Ge). The trace addition of nickel and germanium increases the fluidity of the solder and improves it's ease of wetting by reducing oxidisation on the surface. It produces bright, smooth fillets without shrink cracks or hot tears. \n\n--Trace addition of nickel produces less short circuits and reduces shrinkage defects \n--Nickel-stabilised inter-metallic layer inhibits copper erosion \n--Increased reliability in harsh environments \n--High ductility ensures long service life of joints subjected to cyclic strain \n--Produces minimal dross \n--Minimal shorts and icicles \n--Wets faster than silver-containing alternatives \n--Produces bright, crack-free fillets \n--Superior performance in marine applications \n--Excellent resistance to thermal f;
