Indium - Model Durafuse LT -Low-Temperature Alloy System

Durafuse LT is a low-temperature alloy system designed to provide high-reliability in low-temperature applications that require a reflow temperature below 210°C. Durafuse LT provides improved drop shock resilience, outclassing bismuth-tin (BiSn) or bismuth-tin-silver (BiSnAg) alloys, and performing better than SAC305 with optimum process setup. Durafuse LT is made up of a low-melting indium-containing alloy and a higher-melting SAC alloy. The SnInAg alloy initiates joint fusion while the SAC alloy provides enhanced strength and durability. Durafuse LT is ideal for high-reliability applications, which utilize thermally sensitive components.
