Can a connection be established from copper wire to stainless steel bus for power connection? [closed]

Just to fill everyone in, copper is a NO NO when it comes to heating anything you might breathe in. You can't make any sort of smoking apparatus out of it due to the toxic gases released. You can use it for parts of the device that aren't being heated at all such as, a mouthpiece or body of the device that isn't taking any significant heat that you might breathe.

Having worked in plumbing for many years, I can tell you that when you cut open a roll of soft copper that's fresh from the factory, the inside of the pipe smells like naptha (mothballs). Don't know why but that, alone, should dissuade you.

Yes, please stick to stainless, kanthal, nichrome or any other *known* safe...

Charges loose their energy within the circuit if they move through a resistor(like a bulb). Now, if I make a circuit with just wires and no resistor, will the charge loose its energy?

One reason of loss of energy of the charge I can think of is that as the charge reaches the positive terminal, it it getting closer to the positive charge which is attracting it, and getting closer to the source of the electric field, and hence, it is loosing potential energy(Similar to the case of the gravity of earth, as we move closer to ground, we loose potential energy). And, this potential energy is converted to the kinetic energy of the charge.

Now, using all of the things I wrote above, we can ask the question that as the charge reaches the positive terminal, where is this Kinetic energy lost? If it isn't lost, then will the battery work properly? Because on reaching the positive terminal, charge already has energy, so what will the battery do?

Of course due to the very...

Copper is an excellent conductor, ductile (can be drawn easily), and reasonably economical. For bare conductors, copper oxidises and the oxide coating prevents further corrosion. While it is heavier than aluminum, it is stronger. The alternative, aluminium, is cheaper than copper, but not as good a conductor. Aluminium is lighter, but weaker, and aluminium transmission lines require a steel-core for strength. Aluminium conductors suffer from 'cold flow', which means that aluminium conductors secured with screw terminals tend to work loose over time. Copper doesn't do this, so copper is preferred for residential/commercial electrical wiring...

causing wide fluctuations of operating tem perature. In addition, the ambient temperature can be expected to fluctuate between daily extremes and between seasonal extremes. The effect of this heat cycling on a poorly designed or improperly installed connection is frequently progressive deterioration and ultimate failure of the connection or associated equipment. Therefore, temperature rise provides an important and quite convenient method of monitoring the condition of electrical connections.

7.3. MEASUREMENT OF CONNECTION TEMPERATURE.- To evaluate the condition of an electrical connection by temperature, the conductor must be energized and carrying as near rated load as possible. Temperature measurement under these conditions, therefore, requires the use of special equip ment, materials, and procedures, a few of which are described in the following para graphs.

7.3.1.Thermometers, thermocouples, and resistance temperature detectors.-

You may have to be careful here depending on your operating frequency, lengths involved, acceptable losses, and the details of the steel wire such as its surface treatment.

At RF frequencies, the high permeabililty of ferrous metals makes them lossy (small skin depth). Consider:
1 meter long AWG14 wire at 100MHz:
Mild steel (resistivity 0.2u-ohm-m, and ur = 800) yields 49 ohms resistance.
Copper (resistivity .0169u-ohm-m, and ur = 1) yields 0.5 ohms resistance.

Also, steel is not all the same. Stainless steel has ur = 1. Galvanized steel wire will have a layer of zinc which may be thick enough to carry your RF current, or maybe not, you would have to know the plating thickness and do the math.

For an antenna, you want the conductor resistance to be sufficiently below the radiation resistance of the antenna. For example a halfwave dipole antenna with radiation resistance of 73 ohms, 10 ohms of conductor resistance causes 1dB of loss. This may be ok in...

All of my J-Pole and Slim Jim antennas are constructed out of Type-M hard copper tubing. Type-M, also known as Red Copper is primarily used in the plumbing industry for supplying drinking water in homes and businesses. Although with the cost of copper continually increasing, the construction industry is shifting towards other materials for plumbing. But like copper tubing carries water in homes, it also can carry electrons in our antennas.

One thing that makes copper an outstanding choice for antennas is that it is a very efficient conductor of electrical energy. In fact about the only common element that is more conductive than copper is silver. You can imagine what an antenna built out of silver would cost.


Weight for weight, outside of precious metals, copper is the best conductor of electricity and heat, it is hardly surprising that about 60% of total copper use is for these purposes.
Copper is used in high, medium and low voltage...

Actually there is quite a lot of iron and steel wire about, often plastic coated, sold for garden and general packaging uses.

A quick google search reveals that specific resistivity for copper is 1.6 x 10 ^-8 ohm meters and iron is around 9.6 x 10^-8...

That is, iron has six times the resistance of copper, almost exactly.

Steel is somewhat between, at 4.5 x 10^-8 approximately. So its about 3 times copper resistance.

Nichrome is 1.5x 10^-6, or about 100 times more resistive than copper...which is interesting, on account of foam cutters etc.

Note also that resistance goes up as teh inverse square of diametr,. so a 10 thou wire is 1/4 the resistance of a 5 thou wire of the same length...

Dunno why you are asking, but I hope that helps.

PS you should never use anything but copper wire if low volt drop is what you want, although weight for weight, Aluminium is better, but it doesn't solder worth a...

Not true about not being able to solder aluminum! You do have to prevent the metal from being oxidized which happens in microseconds. Once the aluminum is "tinned", then no problem soldering.

There are special fluxes that allow the aluminum to take solder. Also, putting the aluminum in an oil bath (including motor oil) and then applying a soldering iron and solder while the aluminum is submerged allows the metal to be "tinned". It is the oxidation that prevents aluminum from taking solder. When oxygen is eliminated then there are no problems.

Stainless steel is another thing. There are fluxes that supposedly allow soldering. However, I have never tried them. As far as aluminum goes, have soldered it numerous times using the oil bath method. As far as galvanic action goes, soldering does reduce this. However, there is always the possibility that galvanic action might cause eventual problems.

I am re-wiring our house and I found some of the positive insulated 5-10amp cables have a layer of black oxide on all the strands for the entire length of the cable.

Does this cause more resistance and if so, is there a danger that the cable might get hotter?

Is there also a chance that these oxidised cables will lead to higher energy consumption and higher electricity bills?

Hi Dan, thanks also for your very expert advice and links.

As I mentioned to Jayeff, I am in Northern Brazil where things are far more lax and sadly often very badly done, which is the main reason that I am doing a step by step re-wire, as I can afford it.

You say that for 15amp and above, you need solid conductor wiring. As the cables will only be feeding a domestic refrigerator, 4 lights and two wall sockets for plugging in tablets, cellphone chargers etc., I have already bought 6mm cable which can handle up to just over 30amp (correct me if I'm wrong).

They will be...

Copper: uses, applications-Metalpedia Copper is a kind of non-ferrous metal which has long been closely connected to human beings. Not only are there abundant resources in nature, but copper also possesses excellent properties. Therefore, it is widely used in electrical power, electronics, energy, petrochemicals, transportation, machinery, metallurgy, light and other new industries and some high-tech fields. Electric power transmission, such as wire and cable, transformers, switches, plug components and connectors, etc.; motor manufacturing, for instance as a stator, rotor, shaft head and hollow wire, etc.; communication cables and residential electrical circuits also need to use a large quantity of copper wires. Vacuum electronic devices such as high frequency and ultra high frequency tubes, crossing the catheter, magnetron, etc. Copper printed circuits require a lot of copper foil and copper base brazing material. In integrated circuits, copper replaces aluminum in...

Common Contact System


Fundamental to the Deutsch connector series is the principle that all wires are terminated by a single contact system. The only variation in contacts is that dictated by wire gauge. The world „common“ describes the Deutsch contact system well. A solid contact can be assembled with the complete Deutsch connector family and applies to a common system of contacts, tooling, processes and terminations.


The basic system uses five contact sizes: 4,8,12,16 and 20. These are the only contacts that an O.E.M. or their supplier need stock in volume. The Deutsch contact is a solid, closed barrel, crimp type terminal, manufactured by a cold heading process using solid copper alloys for sizes 20,16 and 12. The contact is interchangeable within the complete Deutsch connector families and are selected based upon the user, s application. Stocking costs, engineering cost and termination costs are slashed, because the...
