Bronze is an alloy whose main constituents are 

Bronze is an alloy whose main constituents are  Correct Answer copper and tin 

Key Points

A combination of a metal with another metal or any other element is called an alloy.

  • Copper is a metal and not an alloy whereas bronze, steel, and brass are alloys.
    • Steel = Carbon + Iron
    • Bronze = Copper + Tin
    • Brass = Copper + Zinc

Concept:

Alloy:

  • An alloy is a homogeneous mixture of two or more metals, or a metal and a non-metal. 
  • Properties of alloys are different from the constituent elements. 
    • They are harder than their constituent metals.
    • They are more resistant to corrosion than pure metals.
    • They are more durable than the metals they are made from.
    • They have less electrical conductivity and melting point than the constituent metals.
    • Some of the properties of constituent elements are retained in the alloy.

Explanation:

List of some important alloys:

Brass

  • It is composed of copper and zinc (Cu + Zn).
  • It is used in making utensils.

Bronze

  • It is composed of copper and tin (Cu + Sn).
  • It is used in making coins, bells, and utensils.

Solder

  • It is composed of lead and tin (Pb + Sn).
  • It is used for soldering (welding electrical wires together).

Stainless steel

  • It is composed of iron, chromium, nickel, and carbon (Fe + Cr + Ni + C).
  • It is used for making utensils and surgical cutlery.

Alloy A contains metals gold and bronze only in the ratio 5: 8 and alloy B contains these metals in the ratio 3: 10. Alloy C is prepared by mixing A and B in the ratio 1: 1. What is the ratio of bronze to gold in alloy C is:
An alloy A contains two elements, copper and tin in the ratio of 2 : 3, whereas an alloy B contains the same elements in the ratio of 3 : 4. If 20 kg of alloy A, 28 kg of alloy B and some more pure copper are mixed to form a third alloy C which now contains copper and tin in the ratio of 6 : 7, then what is the quantity of the pure copper mixed in the alloy C?
An alloy A contains two elements, copper and tin in the ratio of 2 ∶ 3, whereas an alloy B contains the same elements in the ratio of 3 ∶ 4. If 20 kg of alloy A, 28 kg of alloy B and some more pure copper are mixed to form a third alloy C which now contains copper and tin in the ratio of 6 ∶ 7, then what is the quantity of the pure copper mixed in the alloy C?
In one alloy, there is 50% steel in its total mass, while it is 75% in another alloy. 15 kg of the first alloy was melted together with 10 kg of the second one to form a third alloy. Find the percentage of steel in the new alloy when it is known that 20% of the total steel is getting diminished during the melting process?
Alloy 1 and alloy 2 are prepared by mixing metals A, B, C and D. The pie charts show the proportions of these metals in the two alloys. If 1 kg of alloy 1 and 2 kg of alloy 2 is melted and mixed, then the resulting alloy will contain what mass of metal B?
Two alloys used to manufacture the third alloy. The first alloy contains Copper and Zinc only, and the second alloy contains Aluminium and Copper only. The Copper content in the two alloys is 40% and 60% respectively. The Zinc content in the new alloy should be between 30 to 40%. How much will be the minimum and maximum Copper content in the new alloy?
Amal preparing an alloy by mixing the other two alloys. The first alloy contains zinc and carbon in the ratio of 1 : 3 and the second alloy contains Aluminium and zinc in the ratio of 2 : 3 (both these alloys have only these elements in the solution). If the new alloy contains Aluminum and Zinc in the ratio of 3 : 5, what is the percentage of carbon in the new alloy?
In an alloy, lead and tin are in the ratio of 2 : 3. In the second alloy, the ratio of same elements is 3 : 4. If equal quantities of these two alloy are mixed to form a new alloy, then what will be the ratio of these two elements in the new alloy?
n an alloy, lead and tin are in the ratio of 2 : 3. In the second alloy, the ratio of same elements is 3 : 4. If equal quantities of these two alloy are mixed to forma new alloy, then what will be the ratio of these two elements in the new alloy?
