Description

Indalloy 281 is a bismuth-based eutectic alloy that melts at 281°F (138°C). It's a popular lead-free bismuth solder alloy. Indalloy 281 is made of 58% bismuth and 42% tin. It's a good low melting point solder for electronics assembly. Indalloy 281-338 is a tin-based alloy that melts through a temperature range of 281-338°F. It's a non-eutectic alloy. Indalloy 281 has the following physical properties: *Density: 8.56 g/cc *Mechanical properties: Metric Indium is a versatile metal that's often used for: *Soldering to gold *Thermal applications *Low-temperature solders *Bonding to ceramics *Hermetic and cryogenic sealing *CTE mismatch Indium-containing alloys melt at temperatures less than 180°C, making them ideal for step soldering or applications that require lower reflow temperatures.
