High copper vs low copper amalgam

WebAmalgam is a metallic alloy formed by reaction between mercury and an alloy in powder form containing silver, tin, copper, zinc, etc. with a very complex metallurgical structure. Powder alloys can be classified into two groups: low copper content or conventional composition (5% or less copper) and high copper content (6 to 30% copper). WebLOW-COPPER AMALGAM These are also known as ‘traditional’, ‘conventional’ amalgam. Low-copper amalgams were used earlier on. Now low-copper amalgam has been replaced by high-copper amalgams. (JF McCabe, AG Walls: 1998) HIGH-COPPER AMALGAM This is the product that is used in the SOH clinic. High-copper amalgam …
