UMM provides high-purity elemental metals or master alloys with purity ranging from 99.9% to 99.9999% (3N~6N) to major alloy manufacturing industries. As alloy additives, its chemical purity is the key to ensuring the accuracy of alloy composition and improving the yield rate. factor. Therefore, based on the same national standard or industry standard, UMM through the combined application of wet purification and fire refining technology, as well as more accurate high-purity metal detection methods, can always ensure that its products are far beyond the national standard and the industry standard. Quality and performance.
