What are the commonly used high lead solder pastes? Any reliable recommendations?

Common high lead alloys and their melting points are:

SnPb92.5Ag2.5 287

SnPb88Ag2 284-292

SnPb78Ag2 268

SnPb95 305-3 15

SnPb90 280-305

Shenzhen Chenri Technology Co., Ltd. has produced a variety of high-temperature and high-lead solder pastes, such as ES-500, ES-650 and ES-660, which are widely used in the packaging and welding of power tubes, diodes, triodes, rectifier bridges, small integrated circuits and other products.
