Wiron
®
light
The new non-precious alloy for metal-to-ceramic work, with lighter oxide
– beryllium-free –
> Simple casting
• Casting temperature only 1350 °C
• Preheating temperature only 800 °C
> Easy finishing
• Light-coloured, thin oxide
> Risk-free working
• Outstanding strength values

Wiron ® light – casting made simple
The 6 g casting ingots can be melted
either with a flame or inductively before
casting by the centrifugal or vacuum
pressure method. The proper moment for
casting is clearly recognisable and the
excellent melting properties of the alloy
ensure reliable filling of the mould. The
lower mould preheating temperature of
only 800 °C gives a very smooth surface,
cuts electricity costs and saves time.
Wiron ® light –
for effortless finishing
The lower casting temperature of only
1350 °C and the preheating temperature
of just 800 °C reduce the reaction
of the alloy with the investment material.
This produces a smooth surface and
makes finishing much easier. The oxide
of Wiron ® light is considerably lighter in
colour compared to conventional NiCr
alloys and is very easy and fast to remove
(see picture).
Wiron ® light – for reliable results
The outstanding strength values of
Wiron ® light make it possible to produce
delicate work without the risk of
breakage. The low casting temperature
gives excellent accuracy of fit. Many
commercially available ceramics display
very high bond strength, with normal
cooling, when used for veneering. If an
excellent, high-lustre polished finish is
required, we recommend the new polishing
paste Wiropol. The tried and tested
Wiron ® system gives extra certainty
of excellent results.
Wiron ® light – the alloy you can rely on
Of course, a biocertificate is available
for Wiron ® light.
