What are ferrous metals?

Ferrous metals contain iron and are generally magnetic.  The word ferrous comes from the Latin word “ferrum”, which means “containing iron”.  Ferrous metals may be pure iron or they may be alloys of iron.  Because quality stainless steel does not stick to a magnet, it is often classified as a nonferrous metal.  However, stainless steel does contain iron and technically is a ferrous metal.

 

What are nonferrous metals?

Nonferrous metals do not contain iron and are generally nonmagnetic.  Some examples are aluminum, brass, copper, zinc, tin, and lead.

 

 

 

Do you buy copper wire with the insulation still on it?

Yes.  There are several grades of insulated copper wire.  See explanations below for detailed information.

 

 

What is #1 copper?

Copper solids that do not have impurities like paint or soldered joints.  Some examples are copper pipe or bare copper wire.  It is acceptable for #1 copper to have surface corrosion.

 

 

What is #2 copper?

Copper solids that have impurities on them such as tin coating, paint, or soldered joints.  Some examples are tin coated copper wire and copper pipes that have soldered joints still attached.

 

 

What is copper lite?

Thin sheet copper such as that used for roofing applications.

 

What is #1 insulated copper wire?

Generally, it is insulated copper wire that contains solid (not stranded) copper wire at least the thickness of a pencil lead.  One example is the wire used to run electricity in your house or apartment.

 

 

What is #2 insulated copper wire?

Generally, it is insulated copper wire that contains thin strands of copper wire.  Some examples are extension cords or power cords for appliances.

 

 

What is mixed low grade copper wire or “#3″ copper wire?

Insulated copper wire in which the amount of copper inside is minimal.  Some examples are the wire in Christmas tree lights and telephone wire.

 

 

What is yellow brass?

Yellow brass generally is composed of 65% copper and 35% zinc.  It is often used in plumbing parts such as faucets and has a yellow hue when it is filed on.

 

 

What is red brass?

Red brass generally is composed of 85% copper and 15% zinc.  It also has many plumbing applications and has a reddish hue when it is filed on.  Any red brass that has a chrome coating is paid according to yellow brass pricing.
