    Chromium is hard, brittle semi-grey metal. As a compound, it has varied and robust colors. Chromium ion forms many coordination compounds. In active and passive forms, the latter gives rise to its corrosion resistance due to a thin surface oxide layer that passivates the metal when treated with oxidizing agents. Active form reacts readily with dilute acids to form chromous salts. It is soluble in acids (except nitric) and strong alkalies, and insoluble in water.
    AEM provides pure chromium products and chromium-nickel alloys, chromium cobalt alloys with high quality and competitive prices.
    Below are some of our standard chromium and its alloy products. If you require customized products, please contact us by email.
