    Specific Gravity of this metal is 7,48684211
    5,69 : 0.17 = 7,48684211
    What is?
    Please can someone respond me I not found this metal with detector!

    Welcome to Tnet

    Having gone to the trouble of measuring the Specific Gravity, did you not then go on to look up the SG values for various metals? They’re easy enough to find on the net.

    Obviously, if it’s an alloy, a whole host of materials could be in the region of 7.5 but, as pure metals, the maximum SGs for silver and platinum are way above the value you quote and aluminium is way below it:

    Platinum: 21.5
    Silver: 10.6
    Aluminium: 2.8

    Tin, as pure metal, would have an SG of 7.5 but of course that’s not the only possibility if your lump of something is one of the denser metals alloyed with others of lower density.

    It is not always favourable to have the membership show the obvious to a query, when the query has already assumed the query is of 2 precious metal groups.

    Lead/Tin/Aluminum are the first thoughts yet discounted usually because that would say it was the end product of a sand casting campfire melt.

    Once again you have asked/stated the answer-yet it probably won't govern a thank you.
    Though you have an excellent record on the ID of items.

    This material was found on the beach! Second time I say Without Detector!
    Here speak for skill!
    Every single post in the forum is about melted cans!
    I think it has indications for natural formation!
    ..., if the can is melted, there will be no base of natural origin!
    Thanks for the comments ...
    I have the feeling that the answers on the topic are aggressive to me!
    I have no indication of this ...
    The metal in the photo looks perfect, not Aluminum ...
    I apologize!

    What about meteor Or sumthing
    Because look like natural formations and doesn’t have specific gravity!

    I'm not being aggressive!

    To achieve a Specific Gravity of 7.5 the material must be either a relatively pure metal which has that specific gravity or an alloy which contains a substantial proportion of a metal which is above that Specific Gravity.

    You say that it’s not magnetic which rules out it having a proportion of iron and probably also rules out a high proportion of nickel. That also rules out any possibility of it being meteoritic. All metallic-looking meteorites are magnetic. Some grades of steel could have an SG of 7.5 and be non-magnetic, despite their high iron content.

    Unless it contains something rather unusual then the only ‘commonly’-encountered metals with an SG of 7.5 or above are (typical values):

    Tin: 7.5
    Copper: 8.9
    Nickel: 8.9
    Silver: 10.5
    Lead: 11.3
    Gold: 19.3
    Tungsten: 19.3
    Platinum: 21.5

    Copper or gold alloys in amounts leading to the alloy having an SG above 7.5 would usually have at least some yellowness in colour.

    Folks here are trying to help you. At 7.48om pure platinum and silver are eliminated. You don't like the answer so we are agressive toward you? I'm not sure what you are trying to say there.

    Yes, it's not silver or platinum due to the specific gravity. The only way to know for sure is to have it analyzed. I use John Attard, Attard's Minerals in San Diego, CA for my xray diffraction tests when I'm stumped. Pretty inexpensive and results are fast. I just sent him one item and it took less than 3 weeks. By looking there is no way we can guess especially if its a blend of metals. A meteorite would be nickel and iron.

    Rule 101:

    If they have to ask if it's a meteor, it's not a meteor.

    If they have to ask if it's a precious metal, it's not a precious metal.

    Rule 102:

    They'll post that they don't know what it is and ask for an ID, once you indicate it's not a precious metal or meteorite, they suddenly know it's definitely a precious metal and you're wrong.

    1: We don't know what part of the world you are from.
    2: From purchasing $Millions in scrap metals over the years I know a bit.
    3: Go to a larger scrap metal yard, brokerage.
    Say the following: " Do you/can you test white metals?
    Will you can you test this, will it cost me anything.
    Most yards will do the 5-10 second test and it will give you base metal indication of what it is.
    30 seconds and it will tell you more information than most will probably understand.
    Best of luck.
    BTW we're not the bad folks here.
    Just trying to figure it out.
