Silver 251, 250 & 20Cd have good fillet forming properties with an ability to bridge wide gaps. Their wide melting range limit their applications. Due to their wide melting range they are somewhat more subject to liquation and may require more care during brazing. Therefore, they are not normally recommended for applications with slow heating rates.
