Suitable alloys of platinum or gold for weaponry
网页2020年7月12日 · Gold is very soft with a hardness of 2.5. Platinum is 3.5. Iron is 4.0 Any alloy of gold or platinum is going to have to fight that lack of hardness. The metallurgy could get quite complicated to get satisfactory alloys. Recommendations. Do a gold or platinum inlay instead of alloy.

网页Magnesium Alloy If your civilization discovers magnesium (high probability as it is earths fourth most abundant resource) you have another high potential component for creating strong alloys. If you'd put aluminium and magnesium together you can create a very strong alloy with a MPa of 450 ( Aluminum alloys ) and very low density, making it ...
Metal or alloy for special sword - Worldbuilding Stack Exchange
网页2021年2月8日 · Why not platinum or platinum-group metals alloy? Platinum 90% / Iridium 10% comes to mind. higher melting point than iron alloys; 3x heavier than or and steel, 2x heavier than lead (in real world, your setup may vary) impressively hard, that's why they made meter standard out of it. expensive
What would be an ideal alloying metal for gold coinage?
网页2018年10月18日 · Less gold in your alloy (gold is heavy, and gold is expensive) Money however, isn't required to be as shiny and stainless as jewelry. It will be worked with a press, and won't require an extraordinary ductility or malleability. We often prefer it to be durable. That' why money alloys were often lower in gold than jewelry alloys.

网页2016年10月13日 · The alloy in that link is mostly iron, but was noticeably more corrosion resistant. This suggests that most anything you can do with iron can be done with an iron/silver alloy, simply by keeping the silver content low. Of course, once you start pushing into the higher levels of durability, such as what you want from steel, it becomes harder.
Is it possible for a mine to contain both gemstones and precious …
网页2018年5月31日 · It's quite common. Silver is often found with lead-zinc (also, lead-zinc). The mines in Sudbury produce copper, nickel, gold, and platinum group metals. Indium is a byproduct of tin mines. A mine I worked at was for antimony but had lead and minor amounts of uranium.

网页2020年9月24日 · $\begingroup$ A lot of metals (or alloy steels, for which one can use other metals without knowing them directly) could be produced by 15th century methods. But you have to provide an explanation for stagnation (or hard limits of what is allowed), otherwise your 15th century setting would become 16-17-18th century before you know it. $\endgroup$

网页2022年12月25日 · Until recently, scientists thought that 16 Psyche was a solid hunk of metal, iron, nickel, gold and platinum. A recent article in Smithsonian suggested that the market price of the asteroid’s metals is 10 quintillion, hence the name “golden asteroid.”
construction - Can Gold Be Used for Other Purposes?
网页2016年1月19日 · To use the nice property of gold to be immune to corrosion you might not want to alloy it but to thinly coat the things to be protected, e.g. in electronics manufacturing Electroless nickel immersion gold (ENIG) is used as surface plating for printed circuit boards to protect copper and nickel traces on the board from oxidation.
Zinc is a precious metal. What alloys are no longer practical?
网页2017年2月22日 · $\begingroup$ Most writers deal with it by making gold, platinum etc magic metals in their world. These are already precious, so it changes nothing fundamental. And is already familiar for your readers. $\endgroup$ –
