Classification: according to the different requirements of use,rhenium pellet/ingot according to the sical properties is divided into "high density rhenium pellet/ingot" and "medium density rhenium pellet/ingot", according to the chemical composition is divided into "high purity 99.99%" and "ultra high purity99.999%.Appearance: Grey or silver metallic square bar or round rod,medium density ingot is dark grey and high density ingot is bright silver.Application: Medium density rhenium bar can be used as additives for superalloys and high density bar can be used for the manufacture of rods,temperature structural parts.Specification: 4N Grade Reâ¥99.99%(calculated by subtractive method,except gas c;            5N Grade Reâ¥99.999%(calculated by subtractive method,except gas c;            Medium density rhenium pellet/ingot, density is about 12/cc            High density rhenium pellet/ingot, density is about 18.5g/ccSizeï¼Square bar (12-16) * (12-16) * (150-500) mm; Round bar D (10-20) *L (50-300) mm. Can be customized as per requirement.
