Description

Gold-based solder alloy. Soft solders are characterized by a liquidus temperature <450°C. High precious metal-containing special soft solders are always used when the properties of the classic SnPb soft solders do not meet the desired requirements. This is the case in different areas of electronics and microelectronics. The gold base special soft solders are characterized by considerable strength values. At the same time, these materials have almost negligible plastic elongation. AuGe12 is u. a. as a mechanically highly durable, corrosion-resistant solder material for hermetically sealing ceramic IC packages and for connecting housing parts made of Cu and FeCoNi alloys at temperatures in the range of 400 to 500°C.

"Typical" values were obtained via a literature search. "Predicted" values were imputed via artificial intelligence technology. While we have placed significant efforts in ensuring data accuracy, "typical" and "predicted" data should be considered indicative and verified by appropriate material testing. Please do contact us if additional information on the the predicted data method is required.
All metrics apply to room temperature unless otherwise stated. SI units used unless otherwise stated.
Equivalent standards are similar to one or more standards provided by the supplier. Some equivalent standards may be stricter whereas others may be outside the bounds of the original standard.
