First there was iron, bronze and then steel...
High Performance Alloys have revolutionised the ways Alloy Wire work. Featuring increased amounts of nickel and chrome, they are therefore more resistant to corrosive environments and extreme high temperatures. For industries such as aerospace, nuclear and others that operate in these challenging conditions, High Performance Alloys play a vital part in the process.
This presentation offers insight into that vital role and the capabilities High Performance Alloys hold.

The rise of the High Performance Alloys
1. FIRST THERE WAS IRON, BRONZE AND THEN STEEL
The rise of the High
Performance Alloys
2. It begins with stainless steel:
what is it?
Iron + carbon are combined to
make steel. Adding alloying
elements like chromium + nickel
makes stainless steel.
Fe + C + Cr + Ni
3. What do the nickel
and chromium do?
They improve the corrosion
resistance compared to steel.
5. Ni
Cr
+
Mo + W +
Al + Co +
Ti + Mn +
Si Ta +
Nb
They have increased amounts
of chromium, nickel and
Exotic elements to work in
extreme environments.
So what are ‘High
Performance’ Alloys?
6. Why work with
‘High Performance’ Alloys?
They are resistant to
extreme environments,
such as exposure to
high temperature or
corrosive liquids and
gases.

What makes them resistant to
corrosion and high temperatures?
Adding an element like molybdenum
(improves the alloy’s resistance to pitting corrosion)
Adding elements like titanium + aluminium
(improves the alloy’s strength at high temperatures)
the ratio of different elements within the alloy
create it’s characteristics.

Alloys and
example
environments
11. Example
applications
n
Springs in high temperature
aerospace engines.
n
Spiral seals in nuclear reactors,
aircraft engines and oil field pipes.
n
Wire mesh in chemical plants.
n
Mesh baskets and hooks inside
furnaces.
12. Springs
What is spring temper wire?
A specific amount of cold work given to
harden the wire during manufacture.
The amount of cold work is different for each
alloy and achieves a condition suitable for
spring forming. Additional ‘heat treatments’
can be used to further enhance the alloy’s
properties for particular environments.
13. n
STRESS RELIEVE: low temperature heating to remove
internal stresses in the wire after cold working e.g. after
coiling into a spring.
n
ANNEALING: high temperature softening of wire to
allow further cold work on the wire e.g. so the wire can
be drawn smaller.
n
AGE HARDENING: heat treatment to increase strength
of finished spring etc.
What is meant by
‘heat treatment?’
14. Ti
Al
+
When heat treated, the small
addition of elements like titanium
and aluminium form bonds that act
like the reinforcing bars in concrete.
This strengthens the wire.

17. NICKEL® 200 NICKEL® 212
are good conductors of
electricity and withstand high
temperature. Thus, used as a
connecting wire to an electric
heating element.
Cold leads
18. Controlled
expansion
NILO® 36 / NILO® 48 / NILO® K
have expansion rates to match
different types of glass. So they can
be used in contact with glass that is
getting hot e.g. electric valves.
19. Constant modulus of elasticity
NI-SPAN-C ALLOY 902®
Can be processed to have a constant modulus of
elasticity between temperatures -45 °C to +65 °C,
making it good for watch and weighing scale springs.
22. How does 80/20
NiCr work?
Electrical wire used at operating
temperatures up to 1200 °C (2200 °F).
It has good oxidation resistance, especially
under conditions of frequent switching
or wide temperature fluctuations,
making it ideal as a heating element.

23. What is 45/55
nickel-copper?
A nickel-copper alloy wire used mainly for its
medium range electrical resistivity and very
low temperature-coefficient of resistance.
Its electrical resistance doesn’t change
as the temperature rises.
This makes it good
for electric resistors
24. What is hot cutting wire?
Our‘High Strength’hot cutting wire range is
used for the cutting of polystyrene (EPS)/foam
and boasts an excellent track record for working
continuously on oscillating cutting frames.
Wire choice is made depending upon the strength,
ductility and corrosion resistance required of the wire.
25. Which alloys are used
for hot cutting?
RW 118, RW 122 RW 70
These alloys have high strength at elevated
temperatures and are used for cutting foam
polystyrene (EPS) and heat sealing polypropylene bags.
RW 41
Exceptional strength at elevated temperatures and is
the highest performing hot cutting wire we offer. It is
excellent at working continuously and on oscillating
cutting frames. To achieve the best cut, adjust the
temperature and cutting speed.
