Question

Which of the following metals can fail in a brittle manner even at room temperature?

Aluminium

 

Titanium

 

Bronze

 

Cast iron​

Answer 1

Explanation:

ans is cast iron because it can failing in a brittle

manner even at room temperature

Answer 2

The following metals can fail in a brittle manner even at room temperature:Aluminium and Bronze , titanium is brittle

Explanation:

Out of the given option , Aluminium and Titanium are metals and Bronze is an alloy .

Metals

The elements that have tendency to loose electron and form electropositive ions .

Na ---1e--> Na⁺

Properties of metals

1 Malleability:process of beating into thin sheets

Metals :are malleable  

2 Ductility:process of drawing into thin wires

Metals:ductile

3. Electrical Conductivity And Thermal Conductivity:

Metals :good conductor of heat and electricity because of free mobile electrons in it

4 lustre:shine

Metals :lustrous  

5.Hardness:

Metals :hard

6.Physical state:

Metals :solid at room temperature

7Melting and boiling point:

Metals :high m.pt and b.pt

8 Sonority:when hit produce sound  

Metals:sonorous

9 Melting and boiling point:

Metals :high m.pt and b.pt

9.Sonority:when hit produce sound  

Metals:sonorous

Alloys

They are homogeneous mixture of two or metals

Properties

They are corrosion resistant

They are comparatively harder etc

Bronze is not brittle because:

It is an alloy with much improved properties .

Titanium being metal is brittle because :on exposure to air ,layers are formed that makes it brittle .

Aluminium is non brittle : it is a FCC metal
