The static creep of amalgams from fifteen alloys.
The static creep of amalgams prepared from fifteen conventional Ag3Sn and higher copper alloys was investigated one week after packing. The rate at which the different alloys develop resistance to creep was compared by testing amalgams at a number of times other than one week. A microfine lathe-cut alloy possesses the highest static creep and the single melt high copper type of alloy the lowest. An admixed high copper group of alloys possesses static creep similar to the silver-copper dispersed alloys. The rate at which amalgam develops a resistance to creep is dependent on the alloy type.
