Q-BI58 is composed of 42% tin and 58% bismuth (known as Sn42/Bi58) lead free wire solder. Q-BI58 is a recommended lead free soldering alternative for heat sensitive components that require a low melting point. The low melting point 138E degrees C prevents thermal degradation of heat sensitive components. Qualitek Sn42/Bi58 alloy meets or exceeds J-STD-006 requirements and all other relevant international standards.
Sn42/Bi58 is sold per 500 gram box and available in a wide variety of Diameters. Most popular are as listed:
