alloys

Question 1

what are alloys?

Answer 1

is a substance made by melting two or more elements together and at least one of them being a pure metal

Question 2

why are alloys made?

Answer 2

many pure metals are too soft to many uses. they can be made harder by adding another element, this often has many more uses

Question 3

how are atoms arranged in a pure metal?

Answer 3

giant metallic structure, arranged in layers. when a force is applied, the layers may slide over each other. the stronger the force, the harder and stronger the metal will be

Question 4

how does an alloy strengthen a metal?

Answer 4

the alloy distort the layers of atoms making it harder and stronger

Question 5

characteristics of an alloy?

Answer 5

• stronger and harder
• less malleable
• less ductile
• more durability
• more corrosion resistant
• more tensile stress and toughness

Question 6

what are common alloys?

Answer 6

amalgam
solder
bronze
titanium alloy

Question 7

what is the use of amalgam?

Answer 7

alloy of mercury, dental filling to fill cavities

strong and durable

Question 8

what is the use of solder?

Answer 8

alloy of tin and lead
used in circuit bonds
low melting point

Question 9

what is the use of bronze?

Answer 9

alloy of copper and tin
statues, medals
is corrosion resistance

Question 10

what is the use of titanium?

Answer 10

allow of titanium and aluminium
aircrafts
high tensile stress and corrosion resistance
