Description

Indalloy 217-440 is a bismuth-based, non-eutectic, low-melting alloy. It's a bismuth-lead-tin solder alloy. Fusible alloys, like Indalloy 217-440, melt at temperatures below 300°F. Bismuth is the main component of many fusible alloys. It influences the melting point and causes the material to expand when it solidifies. Indalloy 217-440 is used for: *Filling blowholes in castings *Low-temperature soldering
