Conductivity and Conductive Elements
Silver also has the highest thermal conductivity of any element and the highest light reflectance. Although it is the best conductor, copper and gold are used more often in electrical applications because copper is less expensive and gold has a much higher corrosion resistance. Because silver tarnishes, it is less desirable for high frequencies ...

What would make Brass magnetic? Finishing
Jan 19, 2009· Instead of just copper and zinc, it's copper, zinc and iron all mixed together in a pot and then poured. Thanks to all. I think you are clutching at straws. Copper and zinc are the components of brass; if it contains iron of any degree that would make it magnetic, you have cheap second rate brass.

Metals
They are not magnetic and are usually more resistant to corrosion than ferrous metals. Brass Brass is a metal composed primarily of copper and zinc. Copper is the main component, and brass is usually classified as a copper alloy. Brass is stronger and harder than copper, but not as strong or hard as steel.

p04Magnetic coins: which coins are likely to be magnetic
Some stainless steels are nonmagnetic. Sometimes coins are described as being made of nickel and will appear of almost the same colour as pure nickel but will be made of cupronickel. This metal alloy is widely used in coin making. It mainly contains copper and is not magnetic. Coins which are unlikely to be magnetic are usually easier to identify.

How to Tell Brass from Copper: Know 6 Properties for ...
Brass on the other hand is an alloy, meaning it is a combination of two or more metals. The reason why it resembles copper so much is because it's actually part copper. Brass is typically a combination of copper and zinc or manganese. It is very hard unlike copper but can break if struck with a metal harder than it.

Galvanic compatibility of aluminum and copper
Aluminum gutter pinholes. The only copper we have is flashing, but a gutter company I spoke with says the salt water air (we are directly on the water) is reacting with the runoff from the flashing to form a battery and causing the corrosion. The corrosion is happening on a few but not all our gutters.

Do You Have A Copper and Zinc Imbalance?
Copper And Zinc Imbalance. Copper and zinc are essential nutrients necessary to sustain the health and function of the human body. These two metal compounds naturally exist in the environment around us including our food and water but can pose major health complications if they are concentrated in our bodies inadequately.

AluminumCopper Alloys an overview | ScienceDirect Topics
Aluminumcopper alloys are of two types: (i) alloys containing copper and aluminum (known as aluminum bronze) and (ii) alloys containing copper, aluminum and zinc (known as aluminum brass). Ateya et al. (1994) reported that aluminumbronze (93 Cu–7 Al) is susceptible to SCC in chloridecontaining solution only when the samples are held at a high anodic potential.

Is Steel Magnetic? Other Metal Magnetic Questions Answered ...
Galvanized steel has a protective coating of zinc, which will not affect the magnetic properties of the steel, iron or other metal type that it is protecting. The zinc coating will not enhance the magnetic properties of the steel, but as long as the underlying metal is magnetic, the galvanized steel as a whole will have magnetic properties.
