We produce a full
range of bismuth based low melting point alloys, also referred to as
Cerro or fusible alloys.
We also supply pure metals, including Tin, Bismuth,
Indium, Lead, Cadmium, Zinc and Antimony.
As well as the above products we also produce a Zinc
repair stick for repairing galvanised finishes, as well as a full range
of Ferro alloys and alloys that can be made to order.

Bismuth is a silvery-white metallic element with a
pinkish tint on freshly-broken surfaces. Bismuth is relatively brittle
for a metal. It has the interesting physical property of expanding when
freezing to a solid.
Bismuth metal is relatively inert and non-toxic. It has
replaced lead in many applications such as plumbing, bullets, birdshot,
metal alloys, soldering, and other applications. Some uses for Bismuth
are: Used as a mild stabiliser in malleable iron or to improve nodule
count in S.G. iron, and some of its other uses include: Fishing
weights, Shot gun cartridges, For additions to glass, For additions to
the galvanising process, and the replacement of Lead in some solders
and Brass alloys, and the production of low melting point alloys which
all have there own individual uses.
Quite interestingly for a heavy metal, Bismuth is
scientifically recognized as one of the safest elements. It is also
non-carcinogenic. Accordingly, a growing number of industrial
applications depend upon it to alleviate specific toxicity or
environmental problems
