Chromium

William Rowland are leading suppliers of Chromium.

Unalloyed chromium is the most "popular" metal surface coating with unbeatable combined durability. This is due to it's relative hardness and corrosion resistance. Through using electroplating techniques, a thin layer of chromium is deposited on pretreated metallic surfaces.

We are the UK Distributor for Delachaux - France, who produce aluminothermic grades 99.4% min for air melting and 99.6% Cr min. for vacuum melt applications. Delachaux also produces a unique double degassed briquette (DDB) 99.8% Cr min. which is equivalent to the highest quality electrolytic grades, for the production of aerospace superalloys and for exacting applications where residual element control is critical.

Chromium Metal melting point = 1860°C
