Ia merupakan bahan dalam beberapa katalis penting. Penggunaan utama kromium adalah untuk paduan dengan besi, nikel, atau kobalt. Penambahan kromium memberi kekerasan, kekuatan, dan ketahanan terhadap korosi pada logam paduan. Dalam baja nirkarat, kandungan kromium dalam komposisi akhir mencapai 10 persen atau lebih. Mengingat kekerasannya, paduan kromium, kobalt, dan wolfram digunakan untuk alat pemotong logam berkecepatan tinggi. Ketika diendapkan secara elektrolitik, kromium menyajikan bahan akhir yang keras, tahan korosi, dan berkilau. Berdasarkan alasan ini, kromium banyak digunakan untuk perapi bodi (<i>body trim</i>) pada mobil dan kendaraan lain. Penggunaan ekstensif kromit sebagai refraktori didasarkan pada tingginya titik lebur, ekspansi termal yang sedang, dan kestabilan struktur kristalnya. <a href="/wiki/Timbal(II)_kromat" title="Timbal(II) kromat">Timbal kromat</a> (PbCrO<sub>4</sub>), padatan yang tidak larut banyak digunakan sebagai pigmen yang disebut kuning krom.<sup id="cite_ref-meduniv_62-0" class="reference"><a href="#cite_note-meduniv-62"><span class="cite-bracket">&#91;</span>62<span class="cite-bracket">&#93;</span></a></sup> </p><p>Kegunaan logam molibdenum adalah untuk paduan baja.
