Description
The “Copper & It's Alloys (55x90cm)” chart is a large-format, educational poster providing a comprehensive comparison of pure copper and its most important alloys, their compositions, properties, and common applications. It is widely used in classrooms and laboratories for metallurgy, materials science, and engineering education.
Key Features
Copper (Cu):
The chart details pure copper’s high electrical and thermal conductivity, excellent corrosion resistance, malleability, ductility, and easy finishing (plating, lacquering). Standard copper grades such as Electrolytic Tough Pitch (ETP) and Oxygen-Free High Conductivity (OFHC) copper are briefly described.
Major Copper Alloys:
Brass: Alloys of copper and zinc (Cu-Zn), with variations (like cartridge brass, red brass, yellow brass) offering a range of colors, strengths, and corrosion resistance; some types may also contain lead or tin for improved machinability or special properties.
Bronze: Alloys of copper and tin (Cu-Sn), usually harder and more wear-resistant, commonly used for bearings, bushings, coins, and sculptures.
Gunmetal: Copper, tin, and zinc—traditionally used in marine applications and cast fittings.
Other alloys: May include copper-nickel, aluminum bronze, phosphor bronze, and more, each with distinct use cases for improved strength, resistance, or machinability.
Composition & Properties Table:
Summarizes nominal compositions, tensile strengths, densities, electrical conductivities, melting points, and color characteristics of pure copper and major alloys.
Applications:
Illustrated common usage for each material, e.g., brass for musical instruments and plumbing, bronze for medals and statues, copper for electrical wiring.
