pure nickel and other precision alloy materials in the form of
wire, strip, rod, bar and plate.
4) Alloy character:
Ferritic alloys allow to reach process temperatures of 2192 to
Corresponding to a resistance temperature of 2372F. All ferritic
alloys have approximatively the same basis composition: 20 to 25 %
of chromium, 4.5 to 6 % of aluminium, balance being iron. Some of
them contain in addition rare earth, as yttrium or silicium. Those
alloys having a ferritic structure, we observe, after a maintenance
at high operating temperature, an important growth of the grain and
a precipitation of chromium carbides at the grain joints level.
This induces an increased embrittlement of the resistance,
especially when it is come again at ambient temperature.
The term "Styrofoam" is a trademarked name of the Dow Chemical
Company. Technically and generically, it's known as "expanded
polystyrene foam" or "EPS foam."
Unfortunately, EPS foam can't be recycled and re-used to make
something new. Plastic soda bottles, plastic bags and other plastic
products are easily recycled, but EPS foam is almost useless in the
recycling industry. Almost none of the recycling companies that
serve residential customers want or accept it.
However, EPS foam has many uses.
• Architects use it to create models of the building they propose
• Designers of every stripe use it to create prototypes of things
they wish to make.
• Artists use EPS foam to create elaborate art pieces.
• Hobby enthusiasts use it build lifelike model railroad scenery
while model airplane and boat makers use it to construct their air
and water vehicles.
• In industry, EPS foam is used to package eggs. It's used as
"shipping peanuts" to protect delicate items that must be sent
through the postal service, UPS or FedEx, to package electronic
products...and the list goes on.
A hot-wire foam cutter is a tool used to cut polystyrene foam and similar materials. The
device consists of a thin, taut metal wire, often made of nichrome
or stainless steel, or a thicker wire preformed into a desired
shape, which is heated via electrical resistance to approximately
200°C. As the wire is passed through the material to be cut, the
heat from the wire vaporises the material just in advance of
The depth of the cut is limited only by the wire length. Width of
cut is limited by throat, if any.
Hot wire foam cutting tables can use a vertical or a horizontal
wire, usually with a horizontal table used as a guide or for
securing the foam work piece.
A table with a vertical wire is mainly used by hobbyists to cut
small and complex shapes such as letters. Only prismatic members
can be cut on this type of table.
Tables with horizontal wires are heavily used in construction and
packaging. The cutting wire is attached to tracks on either side of
the table enabling it to be moved up and down making cuts very
exact. This table type can also perform angular cuts.
