Laramid is an aromatic polyamide, for
the same applications of Latamid but
with marked mechanical characteristics,
mainly in terms of load at break and
thermal performance. Low moisture
absorption and high chemical inertness
make Laramid suitable for applications
at high temperature and in the presence
of water vapour and aggressive water
additives.
Larton is PPS reinforced up to 40%
with glass fibre, suitable for improved
dimensional stability applications, and
to ensure a constant performance in
severe working conditions, in terms of
temperature and chemical attack.
Thank to its internal technical and
design service, Lati is able to assist
customers in the substitution of metal
with FE structural analysis, co-design
and engineering support, and tailor-
made compounding.

New pipe
dimensions from
Felker Brothers
Felker Brothers Corporation has
introduced 14" to 24" ASTM/ASME
A-312 sch40S pipe to its product line.
The new products join a range that
includes stainless steel pipe and tube in
ASTM A-778 and ASTM A-269/SA-249,
and stainless steel fittings such as
elbows, concentrics, eccentrics, tees,
laterals, wyes, stub ends, face rings and
flanges.
Special alloys, diameter sizes, gauge
thicknesses and lengths up to 50ft are
available upon request.
The company also provides additional
testing options, including x-ray,
ultrasonic and liquid dye penetrant, and
end preparation options such as roll
grooving, belling, tangents, bevelling,
flanging and plastic end caps.

single operation, reducing further
finishing steps and the impact on price
of scrap handling and disposal.
The company’s proposals include
Latamid and Latigloss: PA66 reinforced
up to 60% with glass fibre. The best
offer in terms of price/performance,
guarantees a mechanical resistance
comparable to aluminium.
The load at break is close to 220 MPa,
a value close to the one of different
metals and alloys, with good chemical
resistance, toughness and impact
strength.
Latamid formulations are suitable
for use in pneumatic valves, in the
thermosanitary sector, to produce
casings and actuators, controllers and
pumps, wherever a high mechanical
performance and reasonable costs are
needed.
Latigloss grades offer the same
mechanical and thermal properties
of Latamid, but surface finish can be
improved, avoiding typical aesthetic
issues due to the presence of glass or
carbon fibres. Latigloss is available in
brass or aluminium pigmentations, to
make plastic parts look like metal.
Precision tube
Osborn Tubes is a specialist manufacturer of precision cold drawn alloy steel
tubes for a diverse range of industries. The company is a member of the
UK-based Osborn Metals Group, and is situated in Longueville, France.
The company offers precison tube in the 2-60mmOD range, with wall thicknesses
ranging from 0.4 to 10mm, in materials including 15CrMoV6, 25CrMo4, T45 and
T60. Applications include precision tubing for commercial and light aircraft,
helicopters and motor sport, and many other demanding applications.
To expand its product range, the company recently introduced two new grades
– GT1000 and GT750 – to provide aerospace performance to the motor sport
industry at a more attractive price level.
Whilst the majority of output is in round tubes, the company can offer more
complex profiles, and can also offer a wide variety of finishes, heat treatments
and testing parameters.
