Q) Alloys

Unit 1 Question:
Alloys are generally less malleable than pure metals,
does this mean they are more brittle?

Harder but more brittle I think...

Yep - usually hard but brittle :)

Why can the alloy solder be used to join metals together?

I'm pretty sure we use it because it has a relatively low melting point but is a good conductor of electricity.

oo but if it has a low melting point does it mean that its more softer --> malleable?

Yeah solder is very malleable, and low melting point. That doesn't make it better for joining things it's just easiest... commercian 40/60 electronics solder has a flux core which allows the alloy to adhere to what its meant to as well, where as without flux it just clumps to itself.
