Silver-based solder

　　Silver-based solder is a solder with silver or silver base, which has excellent technical property, low melting temperature, good moist and penetration ability as well as high rigidity, good plasticity, electric condution, and good anti-corrosion. With the support of silver solder agent, it can be used in all black metal and non-ferrous metals except aluminum, magnesium, and some metals with lower melting point.
