    Most are yes.
    The only one's I've come across that are not.. look like steel and have rust on them.
    But yep if it looks to be brass.. chances are it is!
    I'm so into scrapping.. When my Steel Toe Boots Wear out, I cut the Steel out of them and recycle the Toe!

    Some are all brass and others are nothing but cheap steel made to look brass like. Knobs are made of everything one can imagine, brass, copper, steel (both magnetic & nonmagnetic SS), nickel plated, glass, porcelain, wood, plastic .......). I'm sure I missed some and others can fill those end. When I first started scraping, my lack of experience let me cut-up and scrap a beautiful door lock & knob engraved copper assembly. This was for a couple of dollars in scrap copper. I realized my mistake at the scrap yard, when an older gentleman behind me, "asked do you know what you just cutup?". He told me to pull it out of the bucket and he would explain it to me after we sold our scrap. I actually pulled all of my scrap copper and brass that day and that turned into one of my best scrap educations to this day. The man and I spent about an hour going through my two brass and copper buckets. He taught me about door knobs and much more that day. The parts that I had not destroyed were worth way more than scrap and the copper knobs that I cutup were worth more than $100 (now were indeed scrap worth maybe a $1). Lots of lessons that day have since replaced that $100 and I reminded how much I have to keep learning. When I get my act together today I'll try and load some pictures of a nice solid brass pull/lock/knob assembly I found just last month. A perfect example of what not to scrap.

    Well partly anyway. The new Kwikset and Schlage lockset that are brass finished like polished, Antique, Bronze have thin layer of sheet brass pressed over a steel backing to give them strength. This holds true for the knob, backplate and deadbolts.
    I cut them in half with a thin cutoff blade to separate them.
    For the most part if you put a magnet to the brass part it will stick because itís grabbing the steel behind the brass sheet.

    most of the ones I come accross are part brass, part steel. Some come apart easier than others. most likely, an all brass one is worth resale.
    Currently looking for a job in or related to scrap/recycling. Relocation is possible for the right offer.

    While a simple file/grinder magnet test will tell you what you have, keep in mind Zinc is non-ferrous and is very close to brass weight. I have some large door handles that after you take the brass finish off are white/silver color (White Brass). I believe it has a higher mix of zinc. Also found on nice sink faucet neck and handles. I have a bucket of items for the yard to test so I can grade it as Zinc or brass but most of the time they throw it in with my Yellow brass.
    I'm going to recycle the world.

    what I love are the old school fire doors with the big brass handles and brass plates on each side that are used to push down to open the door not like the steel ones today but the good old ones those plates at times I have weighed them out to almost 5lbs

    I replied to this post back on New Years and said I would post a picture of a "better than scrap" example of door hardware. Well I was a "little" hung over and forgot, so here it is a few weeks later.

    I test with a magnet, all new ones are steel old ones are brass with some small exceptions. Magnetic I throw in shred, not magnetic dirty brass unless you dismantle it. Also most old hardware was brass even hinges and locks
