Chromium (Cr) Pellets And Pieces, 99.5%-99.99% Purity (Request Current Price)

ZHC LAB Chromium (Cr) pellets and pieces are high-purity source materials supplied for thin-film deposition research, evaporation source loading, alloy preparation, and laboratory materials development. The pellet and piece formats are convenient for weighing, loading, and small-batch experimental workflows where material identity, purity selection, and clean handling are important. Pricing requires a current quote because high-purity metal costs vary with purity, package size, and material market conditions.
