• Bronze is an alloy traditionally composed of copper and tin.
• The archaeological period in which bronze was the hardest metal in widespread use is known as the Bronze Age.
• Brass is an alloy of copper and zinc, in proportions that can be varied to achieve varying mechanical, electrical, and chemical properties.
• Brass is more malleable than bronze or zinc. The relatively low melting point of brass (900 to 940 °C) and its flow characteristics make it a relatively easy material to cast.
• Gunmetal, also known as red brass in the United States, is a type of bronze; an alloy of copper, tin, and zinc. Proportions vary but 88% copper, 8–10% tin, and 2–4% zinc in an approximation.
• Originally used for making guns, it has largely been replaced by steel for that purpose.
• Nickel-Steel alloy is the most important among all the steel alloys due to its use in various places all around the world. It is formed by adding nickel and iron. It has a content of carbon too. It contains 0.35% carbon and 3.5% nickel in its composition.
