If your trombone was made of pure copper or pure zinc, it wouldn't sound nearly as beautiful as a brass trombone. 如果你的长号是纯铜或纯锌,它不会听起来像黄铜长号那么动听。 Another alloy, a combination of copper and nickel, resists corrosion. 另一种合金,铜和镍的组合,抗腐蚀。 It does no...
It is one reason that ship hulls are made of copper-nickel alloys. These alloys are also hard for the barnacles to stick to. If these little shellfish adhere to the hull of a ship, it produces drag, slowing the vessel down. Copper's also a key material used in solar heating units an...

Besides the nickel that can be found on land, a similar volume is also freely strewn around the seafloor in manganese nodules-- metallic deposits that can range from a few millimetres to tens of centimetres in size. These nodules can also contain iron, copper or cobalt. The content of metal...

Wendy Caldwell, a scientist at Los Alamos National Laboratory, told Space.com that some of her most promising results, including the findings of a 2020 study, had the asteroid being made of Monel, a metal that is made mainly of nickel and copper and is thought to be representative of the...
Unlike other forms of plating, electroless nickel does not require an electrical charge through the part. The nickel salts used in electroless nickel plating typically contain phosphorous or boron. The type of nickel you will need depends on the desired properties of the final part. Nickel-...
aThe thin, sputtered metallization is more brittle and used where signal to noise requirements dictate very low mass loading by the electrodes. Our standard sputtered metallization is 700 A of copper covered with 100A of nickel, which has good conductivity and is resistant to oxidation. Other meta...
1. A graphitic cast iron consisting essentially of about 2% to about 4% carbon, about 1.5% to about 3.5% silicon, up to about 36% nickel, about 0.005% to about 0.06% magnesium, about 0.001% to about 0.015% of a metal from Group IIIB of t... RD Schelleng - US 被引量: 41发表:...
