mkg-1093	Aminatun, Aminatun	The Copper concentration variation to physical properties of high copper amalgam alloy	2006	5	.pdf	application/pdf	3620	230	50	The conventional amalgam contains lower Cu concentration (0–6%) and high copper amalgam alloy contains higher Cu concentration (12% or more).2,3 Based on the concentration of zync (Zn), amalgam is divided into 2 types i.e. the blended alloy type with 1% zync content and composition alloy with 0% zync content. Whereas amalgam thermal expansion coefficient on Cu 29% is (2.17 ± 0.91)10-3 mm/°C is the lowest value compared to other Cu concentration.	cache/mkg-1093.pdf	txt/mkg-1093.txt
