Aluminium Power Point Presentation SA JBP
This document discusses the properties, forms, uses, and advantages of aluminum. It notes that aluminum is a lightweight, non-ferrous metal commonly used today. It exists naturally in the earth as bauxite ore and can be extracted. Aluminum has high strength to weight ratio, good conductivity, and is corrosion resistant. It is used in various forms like casting, extrusion, sheets, foil and powder. Common applications include doors, windows, siding, kitchenware, cables, and vehicles where its properties allow replacement of heavier metals. Aluminum provides advantages like low weight, corrosion resistance, and ability to form useful alloys.
