Copper and zinc atoms are different sizes. This distorts the regular lattice structure in brass, so layers of atoms cannot slide over each other so easily. This makes brass stronger than copper or zinc alone.

Why is the hardness of brass different from other materials
Hardness varies greatly depending on the alloy used or whether it is pure elemental copper and/or aluminum. Brass is naturally an alloy of copper and zinc, and a certain alloy of metal elements tends to increase in hardness, but if a person wants to buy an aluminum-related part, it will be very difficult to buy aluminum.
Which of the following is a characteristic of brass
The metal has low friction. Brass is undeniably a soft metal that can be found in applications where easily accessible sparks are needed. The alloy has a relatively low discoloration point. It is a good conductor of heat. Brass is resistant to corrosion, including galvanic wear from salt water.
Is brass harder than pure metals
In an alloy, there are indeed atoms of different sizes. Smaller and sometimes larger atoms distort the layers of atoms in a pure metal. This means that a lot of force was required to wear the overlapping layers. The alloy will be harder and stronger than real metal.
Why is brass stronger than either pure metal
For example, the zinc content of brass helps improve the ductility as well as the strength of copper-based brass. The higher the concentration of zinc oxide in brass, the more ductile and stronger the alloy.
Why are they harder than pure metals
Alloys contain atoms of various sizes. These different sizes often distort the arrangement of the atoms. This makes it difficult for the coatings to slide over each other, since the alloys are harder than raw metal.
Why are alloys better than pure metals
Metal alloys are composed of dissimilar atoms, the absolute metal, where the atoms are the same in every way. This makes it difficult for the atoms to move closer to motion in metal alloys, which is why they tend to be much stronger and harder than pure metals.

How is zinc extracted from its ore zinc sulphate or zinc carbonate
Answer: Zinc is produced from sulfide ore and carbonate ore by roasting, the process used is called calcination. Explanation: … It happens in ores that they are sulfide or carbonate.
What explain the bounce of a few alpha particles when a thin gold foil is bombarded with a beam of alpha particles
Summary. Bombardment of gold foil containing alpha particles has shown that an exceptionally small percentage of alpha particles are deflected. The model nucleus of this atom consists of a small, dense, positively charged nucleus surrounded by a cloud of electrons.
