Non ferrous & Aplications

Material name Composition Properties Applications
Aluminum / Aluminum alloys Pure metal / Easily alloyed with small amounts of copper, manganese, silicone, magnesium, and other elements Low density, good electrical conductivity (approx. 60% of copper), nonmagnetic, noncombustible, ductile, malleable, corrosion resistance; easily formed, machined, or cast Window frames, aircraft parts, automotive parts, kitchenware
Brass Alloy of copper and zinc, 65% to 35% is the common ratio Reasonable hardness; casts, forms, and machines well; good electrical conductivity and acoustic properties Parts for electrical fittings, valves, forgings, ornaments, musical instruments
Copper Pure metal Excellent ductility, thermal and electrical conductivity Electrical wiring, tubing, kettles, bowls, pipes, printed circuit boards
Lead Pure metal Heaviest common metal, ductile, and malleable, good corrosion resistance Pipes, batteries, roofing, protection against X-Rays
Magnesium / Magnesium Alloys Pure metal / Used as an alloy element for aluminum, lead, zinc, and other nonferrous alloys; alloyed with aluminum to improve the mechanical, fabrication, and welding characteristics Lightest metallic material (density of about 2/3 of that of aluminum), strong and tough, most machinable metal, good corrosion resistance, easily cast Automobile, portable electronics, appliances, power tools, sporting goods parts, and aerospace equipment
Nickel / Nickel Alloys Pure metal / Alloys very well with large amounts of other elements, chiefly chromium, molybdenum, and tungsten Very good corrosion resistance (can be alloyed to extend beyond stainless steels), good high temperature and mechanical performance, fairly good conductor of heat and electricity The major use of nickel is in the preparation of alloys or plating – frequently used as an undercoat in decorative chromium plating and to improve corrosion resistance; applications include electronic lead wires, battery components, heat exchangers in corrosive environments
Titanium / Titanium Alloys Pure metal / Easily alloys with aluminum, nickel, chromium, and other elements Low density, low coefficient of thermal expansion, high melting point, excellent corrosion resistance, nontoxic and generally biologically compatible with human tissues and bones, high strength, stiffness, good toughness Aerospace structures and other high-performance applications, chemical and petrochemical applications, marine environments, and biomaterial applications
Zinc / Zinc Alloys Pure metal/ Metal is employed to form numerous alloys with other metals. Alloys of primarily zinc with small amounts of copper, aluminum, and magnesium are useful in die-casting. The most widely used alloy of zinc is brass Excellent corrosion resistance, light weight, reasonable conductor of electricity Used principally for galvanizing iron (more than 50% of metallic zinc goes into galvanizing steel), numerous automotive applications because of its light weight
