WebIron Chrome Aluminum alloys form a light grey Aluminum Oxide (Al2O3) at temperatures above 1,000°C (1,832°F) which increases corrosion resistance as well as acts as an electrical insulator. The oxide formation is considered self-insulating and protects against short circuiting in the event of metal to metal contact. The creation of metal alloys account for 85% of the available chromium's usage. The remainder of chromium is used in the chemical, refractory, and foundry industries. The strengthening effect of forming stable metal carbides at grain boundaries, and the strong increase in corrosion resistance made chromium an important alloying material for steel. High-speed tool steels contain between 3 and 5% chromium.
