Aluminium is a remarkable material for its low density and high strength per weight ratio. It's ability to resist corrosion through a phenomenon of passivation. Aluminium and its alloys find use in the aerospace industries, transportation and building industries to name but a few applications.
Brass is used in decorative applications which offer stunning finishes such as its bright gold-like appearance or in an antiqued finish. Brass finds uses in buildings, locks, gears, bearings and doorknobs to name a few of its applications.
Copper is one of the few metals that can occur in nature in a directly usable metallic form. Copper is used as decorative elements buildings, roofing and piping.
Carbon steel is the most commonly used steel because of its price. Mild steel contains approximately 0,05 - 0,25% carbon making it malleable and ductile to allow use to fabricate into most sections.
Stainless Steel are most notably for their corrosion resistance, which increases with increasing chromium content. Additions of molybdenum such as in 304 and 316 increase corrosion resistance in reducing acids and against pitting attack in chloride solutions. Stainless Steel are rolled into sheets, plates, bars, wire and tubing to be used in cookware, cutlery, surgical instruments, major appliances and construction materials in large buildings.
