Cold welding is done by applying enough pressure to break the oxide surface which leads to adhesion. This means an instant attachment can be created in just fractions of a second with bare minimum pressure and will last indefinitely. Because of its unique properties, indium can cold weld to itself effortlessly.
Cold welding indium to indium produces a clean, efficient bond that doesn’t change the properties of either piece of metal. When using techniques such as ultrasonic and laser welding, the properties can sometimes change. Higher purity, oxide-free indium wires can create a strong bond that will remain solid up to 157°C. An indium, cold-welded bond can also endure cryogenic temperatures while maintaining excellent thermal and electrical properties.
