Product Overview
Adams supplies a full selection of magnetic products:
Soft Ferrite Information
Ferrites concentrate electromagnetic fields to transmit electrical signals
and power over a wide frequency range. Ferrite cores are the primary products
for inductive components, which are used, for example, in switch-mode
power supplies for industrial and entertainment electronics as well as
for information and communications. Ferrites are also key components of
DSL technology for high-speed Internet access. They are taking on new
applications in automotive electronics as well.
Adams supports soft ferrite industry as an authorized stocking distributor for several manufacturers, including Ferroxcube (formerly Philips), EPCOS (formerly Siemens), Arnold powder cores and more. We carry all types of ferrite cores and accessories, and offer many value-added services along with our vast product selection.
Permanent Magnet Information
Below are brief descriptions of the types of magnetic materials which
Adams specializes in. These descriptions are short and simplified, intended
only to give a basic understanding of the materials. Our experienced staff
can provide application and engineering assistance, selection suggestions,
samples and other services, usually at no charge
to our customers.
Flexible Magnets
Flexible magnetic material is by definition a thermoplastic product.
It is the only type of magnet which can be bent and flexed without affecting
its performance. It can be magnetized using several different methods
to fit various applications. Its natural color is dark brown.
Ceramic Magnets
Ceramic ("hard ferrite") is rigid and brittle and provides
good magnetic performance. It is a very economical material. Ceramic
can only be cut or ground to size using diamond wheels before it is
magnetized. Its natural color is black.
Alnico Magnets
This aluminum-nickel-cobalt alloy is more expensive than flexible or
ceramic, but is excellent for high temperature use, and is readily available
in rods or bars. Close tolerances can be held by grinding to customer
specifications. Alnico as cast is gray to dark brown in color, but looks
bright metallic when ground.
Rare Earth Magnets: Neodymium-Iron-Boron
and Samarium Cobalt
These materials are more costly by weight but deliver "incredible
strength in a small package." Some oxidation and high temperature
concerns exist. Rare earth materials can be cut and ground to specifications
before magnetization. Their natural color is gray, but they are normally
supplied with a nickel or other coating.
Magnetic Assemblies
Magnetic assemblies are up to 32 times stronger than magnets by themselves!
Our standard assemblies are made with ceramic magnets and steel housings.
The key is in the fact that we magnetize the magnet and the metal together,
creating a strong magnetic circuit. Assemblies are the only part of
our product line that can be rated by their pull strength.
