What is present in brass metals and bronze metals ? What is common in both metals ?
Answers
Answer:
Composition: Brass is an alloy of copper and zinc. Bronze is a metal alloy consisting primarily of copper, usually with tin as the main additive, but sometimes with other elements such as phosphorus, manganese, aluminum or silion
Explanation:
metals:
Brass vs Bronze
Brass Bronze
Composition: Brass is an alloy of copper and zinc. Bronze is a metal alloy consisting primarily of copper, usually with tin as the main additive, but sometimes with other elements such as phosphorus, manganese, aluminum, or silicon.
Properties: Higher malleability than zinc or copper. Low melting point (900 c); flows when melted. Combinations of iron, aluminum, silicon & manganese make brass corrosion resistant. Susceptible to stress cracking when exposed to ammonia. Not as hard as steel. Hard and brittle. Melts at 950 centigrade but depends on amount of tin present. Bronze resists corrosion (especially seawater corrosion) and metal fatigue more than steel and is also a better conductor of heat and electricity than most steels.
Color: Muted yellow, somewhat similar to gold, but duller. Reddish brown.
Uses: Decorative; Low-friction applications (locks, gears, doorknobs, ammunition, valves); Plumbing / electronics; Musical instruments for acoustic properties; Zippers & uses where it’s important to negate spark (fittings & tools around explosive gas), boat and marine hardware Used in boat and ship fittings, propellers and submerged bearings because of resistance to salt water corrosion. Widely used for cast bronze sculpture; Bearings, clips, electrical connectors and springs; For top-quality bells and cymbals.
History: Brass was first known to exist in about 500 BC. Bronze dates to about 3500 BC.
Answer:
Brass is similar to bronze,another alloy containing copper that uses tin in place of zinc,both bronze and brass may include small proportions of a range of other elements including arsenic, lead, phosphorus,aluminium,manganese,and silicon.
