i know but i am not going to tell you..
Gunmetal is typically composed of copper, tin, and sometimes other elements like zinc or lead. The composition can vary depending on the specific application, but the general ratio is around 88-90% copper, 10-12% tin, and trace amounts of other elements.
You can use a process called friction welding to join copper and aluminum pipes. Friction welding involves generating heat through friction between two materials and then applying pressure to create a bond. This method is effective for welding dissimilar metals like copper and aluminum.
You can buy an auto transformer with 0-120-240 volt output at electrical supply stores, online retailers such as Amazon or eBay, or specialty electronics stores. Make sure to verify that the transformer meets your specific voltage and power requirements before purchasing.
Due to the heavy coils found inside the body also you will find an insulation that is oil type, that s why it s so heavy , but if u look at the dry type transformer u will find it so light and compact that s all i know my sir Eng: Amr <<>> The reason that power transformers are so heavy is from the steel laminations that the core of the transformer is built from. The outside transformer is constructed out of steel which also adds to the weight. Transformer coils these days are using aluminium wire for the primary and secondary wraps. This keeps the weight down and also helps in preventing copper theft.
Don't check transformer windings with an ohmmeter. All you can do is determine if there's a break in the wiring. If it's reading as "open", then you know that the transformer is broken. It is not repairable without a considerable effort. I'm curious as to how you obtained that transformer. It's quite dangerous and you shouldn't play with it unless you know what you're doing. You are likely to be killed if you try to power it up. DO NOT try to use this in a prank. There are lethal consequences.
because it will contain a magnet inside that spins with copper windings like a car alternator
The connections on a transformer are circuit ties for the primary and secondary windings, and any taps. This is a very general question, and only a very general answer can be given. The basic transformer (outside the autoformer) has four connections, and two of them are for the ends of the primary windings, and two of them are for the ends of the scondary windings. Certainly there are many variations on the theme for taps in the primary and/or secondary, additional primary or secondary windings, different windings for different phases (as in power distribution applications), etc. More information on transformers can be had by using the link to the Wikipedia article on these electrical and electronic devices that are used to step up voltages, step down voltages, or isolate electrical circuits (as well as a number of other things).
You cannot 'reverse' the polarity of a transformer -it is either wound with 'additive polarity' or 'subtractive polarity', and there's not much you can do about it! For a single transformer, its polarity doesn't really matter. But if you are going to parallel two transformers, then you must know the polarity of each transformer in order to avoid harmful circulating currents in their secondary windings.
Fiber Optic cables do not use copper wires; they use either glass or plastic for the transmission medium. Aluminium is also used in certain applications, instead of copper, as it is cheaper although very slightly less conductive. I don't know the present situation, but aluminium-cored wires were introduced into the British telephone networks in the 1970s, at least for local distribution; whilst aluminium bar material was used for the main bus-bars supplying low-voltage power to the switches in the telephone exchanges.

copper bus bar,sqmm X 1.3times, aluminium means sqmm X 0.8 times.. but cable wise dont know can any1 tell me..
A radio transformer is a transformer having a tapped winding or two or more windings designed to furnish inductive reactance or to transfer radio-frequency energy from one circuit to another by means of a magnetic field; may have an air core or some form of ferrite core. Also known as radio transformer.

Aluminium alloys which may include magnesium. If you really want to know, open one up! Plastic Copper Silicon Gold beryllium glass epoxy resin
The French lady has the transformer , But then Tesla was blamed you will know it at the ending.
