AND TUNGSTENE ALLOYS
A grey metal, a little less hard than steel, it offers the advantage of little
warping under mechanical stress, even in high temperatures. It is used to
manufacture filaments in incandescent lamps and in the operational space travel
Tungsten alloys such as Denal, Infermet, Sparkal, Carbene, Cutene, Cunitene,
Frénal (all registered trademarks), are used as balancing weights due
to their higher density (gyroscope tops), anti-radiation shielding due to
their high radiation absorption properties (nuclear, medial applications),
and for their hot and cold mechanical properties, de projectiles, boring bars,
tightening clamps for hot matrixing.

is equipped to machine numerous metals, some known and some less known, in
particular those described below.
The information below is a first general approach to their properties and
Steel (general term) is an iron and carbon alloy in variable
amounts. Most ordinary steels are carbon steels with under 1.7% carbon. They
are harder than iron, and the more carbon they contain, the harder they are
(but the more brittle too). Combining other materials produces special steels.
Metal treatments are applied to steel to give it tensile and traction strength
properties (quench hardening). In order to avoid corrosion (rust), it is protected
by a fine layer of metal, tinplate for tin, zinc for galvanised steel, chrome,
or anti-corrosion paints.
These are steels containing other elements in addition to iron
and carbon, added in variable amounts to give the alloy special properties.
Thus adding chrome produces non-oxidising high resistance alloys (minimum
12 % chrome), such as stainless steel or refractory steel. Adding nickel reduces
heat expansion (the advantages are combined for steels containing nickel and
chrome). With manganese, the steel is more resistant to impacts. Silica is
added to steels intended for the electric industry. Fore increased hardness,
tungsten, molybdenum or vanadium is added. Etc...
Kovar and Dilver (registered trademarks) are special steels
containing less than 2 % carbon, which nickel and cobalt are added to, giving
alloys resistant well temperature changes. They are often used in the fabrication
of metal threads built in ceramic and glazing, and in the packaging industry.
(melt point 1449º C, annealing point 1093º C).
Aluminium is an abundant element of the earth's crust, as it
is made from bauxite, which is found in clay and feldspar.Aluminium is a white,
soft, malleable, light, highly conductive, reducing metal that does not corrode
in air (due to the formation of a protective layer of oxide). It is used alone
or in alloys with lithium (light), with manganese (high mechanical resistance),
with silica, with steel (alnico), etc...
It is highly used in the aeronautical, automotive, and electronic industries
(high voltage lines), in the packaging industry, and one of its advantage is
it is recyclable. (density 2.7, melt temperature 659º7C).

NON FERROUS ARCAP ALLOYS
Non ferrous Arcap alloys offer interesting features in terms of corrosion resistance
with most chemicals (resistance to pipe scaling and clogging due to water),
of lack of disturbing magnetic effect, temperature variation resistance and
low temperature resistance. When annealed, they allow deep sleeves due to an
elongation that can go up to 45 %.
Pure iron, which contains
very little carbon (typically less than 0.005%) is know for its resistance to
corrosion (the metal generates an even protective layer of oxide but does not
corrode) and its forgeing properties. Indeed, it warps when warm, can be elongated
cold without rupturing, is easy to weld, cools more slowly and keeps its temperature,
and in terms of aspect, looks warmer due to its finer grain. It is used in the
locksmith industry and numerous art activities such as sculpting, ironworking

Do not hesitate to ask us to take advantage of its over 30 years' experience.
A malleable, highly ductile and resistant metal, nickel is
non oxidising at ordinary temperatures and attracts iron under 370ºC.
It is used in many alloys such as iron-nickel (stainless steel, permalloy,
platinite, invar, maraging), nickel-chrome (inconel), nickel-copper (monel),
nickel-copper-zinc (German silver, nickel silver), but also in nickel coating,
i.e. the application of a layer of nickel by electrolysis.

This metal, whose aspect is close to that of silver, is malleable
and ductile, and its properties are its high melt point (3000ºC) and
boiling point (5427ºC). It forms alloys withstanding high temperatures,
such as in nuclear ovens and reactors. In its oxide form, it is used in the
fabrication of very high refractive coefficient glasses. (Density 16.6).
The nobium is a rare metal, which is used generally in the revetment of the implants medicate them due to his excellent capacities of resistance to the oxidation and his qualities of adhesion to the metal support.

The company works many plastics, increasingly used in place of metal parts, because metals are often heavier, more susceptible to corrosion, or just more expensive.
The increasing use of plastics is explained due to specific technical features that metals don’t have, such as greater elasticity (PEHD) , or conversely high stiffness with a low coefficient of friction (POM), better expansion coefficient , good resistance against chemical products (PTFE , PE), high temperatures (PEEK), impacts (PC, PET, PMMA) and abrasion (PFTE, rigid PVC, PET), or also, an excellent ability to absorb vibrations (ABS).
They serve as protection because of their lower thermal conductivity or as insulator of electrical cables by their very low electrical conductivity (PTFE, PEHD).
The use of plastics is prevalent today in all industries, without to forget aeronautics, aerospace and medical.
