i have started this post in this section in the hopes that anyone will share there knowledge on locating part numbers & the data sheets for those parts
in a sense a tutorial on knowing your parts and how to find out what they are made of (Gold or Brass) (Silver or Tin)

i will start with a question, these are some type of ceramic with gold plated termination points on each end, there is a wire running through the centre like if it's a fuse
don't know what there called i just have this photo & numbers that are on the parts:

LF5A
LF8A
LF10A
LF12A
LF15A

that looks good but I don't use a fancy phone, just a cheap $25 job to take calls.

there's a lot of tiny things on boards yeah, right now i'm trying to figure out what the small silver coloured rectangular thing with thin gold around the edge is.

?? where are you seeing this "rectangular thing" ??
 
I think the're crystal oscillators.
They have a gold trimming along the side, it seems there's many types as a common one is on motherboards.

anyway, I been looking up DS Relays. Contact material - Ag(Au clad)
so does that mean the contacts are solid silver with gold plating?

Picture came up hopeless but here's one I opened up..

The 3rd item is a mounting bracket of sorts, it's magnetic.
The 4th item is a copper thing with a little gold plated pieces on the tip and the base, so is this Ag(Au clad)? meaning silver with gold plating?
The 5th item are gold plated contacts, so again, silver with gold plating?
The 6th item is non-magnetic and appears to be tiny bits of silver?`

To the left are other types that have various gold plated contacts, again, would they be gold plated on silver or copper? seeing as though data sheets say Ag(Au clad) i'm assuming they are solid silver with gold plating.
