For more than 40 years, Argen Corporation has been one of the largest dental gold producers in the United States and one of the largest in the world. Argen's manufacturing facility is equipped with weighting tolerances of hundredths of a gram to microscopic analysis confirming homogeneous alloys. Using advanced vacuum metallurgy techniques and continuous casting fabrication methods alloys of quality can be produced. The company utilizes computer programs that are developed especially for dental alloy systems that vary theoretical compositions searching for the optimum combination for each application. Thousands of possible alloy compositions can be evaluated before the best one is determined. The alloy then undergoes functional evaluation in a dental laboratory followed by extensive field-testing. Argen Corporation is headquartered in San Diego.
