Quick Answer: What Grade Of Copper Is In Electric Motors?

The copper content varies among different types of motors, while small motors have a higher percentage of copper per weight than heavy motors. On average, fractional electric motors are 9-10 percent copper by weight. AC motors average 7-9 percent copper; DC motors have 15-18 percent copper content.

What type of metal is in an electric motor?

Powder metal components for motors generally consist of iron, nickel, and cobalt. Iron is the cheapest of the three, so many designers turn there first. Cobalt is rarely used on its own, but is sometimes added to iron.

How much is an electric motor worth as scrap?

Most scrap yards, including Scrap Stop, offer a price for electric motors, so that you don’t have to worry about dismantling at all. This price changes based on your region and over time but the current price for electric motors is around 15 cents per pound*.

Are motor windings copper?

In most circumstances the motors are copper wound and could be worth more money if you wanted to take them apart, but sometimes they are wound with aluminum. In the case of aluminum wound motors, we never suggest taking them apart but only scrapping them.

How much copper is in an electric motor?

On average, fractional electric motors are 9-10 percent copper by weight. AC motors average 7-9 percent copper; DC motors have 15-18 percent copper content.

What parts of an electric motor are copper?

The part of the motor that moves, called the rotor, is often a steel shaft that has metal plates that are wrapped in wire attached around it. These wires carry electrical current and so are usually made from copper.

Can I melt down pennies and sell the copper?

It is not illegal to melt, form, destroy, or otherwise modify US coins, including pennies, unless the objective is fraudulent or with the intent of selling the raw materials of the coins for profit. Projects that use coins as materials are entirely legal in the United States.

How many grades of copper are there?

Copper grades are divided into six families: coppers, dilute copper alloys, brasses, bronzes, copper-nickel alloys, and nickel-silver alloys. The first family, the coppers, is essentially commercially pure copper, which normally is soft and ductile and contains less than about 0.7% total impurities.

What is considered dirty copper?

For example a copper pipe that has not fittings or or material on it. Dirty metals are those that have another material along with the metals we are looking for. For example copper wire with a plastic casing around it would be considered dirty. A tube of copper with brass fittings on it would also be considered dirty.

Can aluminum replace copper in electric motors?

Due to the better connection to the laminated core and more favorable utilization of the installation space results in a much better thermal and electromagnetic behavior. For this reason, it is possible to replace wound copper coils with cast aluminum coils for improved performance and lower material costs.

Which motor is good copper or Aluminium?

Copper is stronger than aluminium. It expands less but both materials have a similar maintenance schedule. Copper can carry almost twice the current capacity of aluminium, which makes them slightly smaller in size than aluminium wound transformers.
