Aluminium - Iron - Silicon

Gautam Ghosh

Introduction

The ternary system contains, and also forms the basis for, many alloys in engineering applications, such as cast aluminium alloys, foil and sheet products for food packaging, capacitors, lithographic printing sheets, soft magnetic alloys for transformers. In addition, iron and silicon originating from bauxite ore and anode material are present in nearly all industrial Al alloys, and the metallurgical grade silicon contains, among others, aluminum and iron as impurities.
