Formula: Ag 72/Cu 28
Form: Coil
Material: Silver/Copper Alloy
Commodity: Precious Metals
Coil Width:
100mm
Silver/Copper Alloy Coil (Ag72/Cu28) is a silver-copper foil from Goodfellow's range of alloy foils. This material exhibits high thermal and electrical conductivity along with good ductility and antimicrobial properties. Potential applications include use as a coating for heat spreaders in electronics as well as biomedical devices and devices where antimicrobial properties are desired. As part of Goodfellow's selection of specialty alloy foils, the Silver/Copper Alloy Coil enables customization for specialized applications requiring a balance of silver's antimicrobial properties and copper's thermal/electrical conductivity.
