hardness 100 Br Al10Fe 1.5
for large parts. Used in the chemical industry,
in naval construction and for parts requiring
resistance to corrosive atmospheres.
hardness 120 Br Ai10Fe3
for larger parts that must be able to
withstand high pressures and tough use even
corrosive atmospheres and under heat,
e.g. chains, gates, worm screws, erosive
liquid pumps, mechanical parts, etc.
hardness 150 Br AI 10 Fe 4 Nl4
Excellent resistance to wear-and-tear
and erosion: mechanical safety parts, e.g.
propellers, gears and clutches, valve seats,
temperatures as low as -180°, bronze
greater tensile strength and elongation
at rupture than
those obtained at ordinary temperatures.
Resistance to atmospheric oxidation is perfect
at room temperature
and remains at excellent levels under higher
NB: These materials cannot be used in
the presence of nitrogen at high pressure
or temperatures. Corrosive testing carried
out on electric railway lines were conclusive
and achieved much greater results than other
non-ferrous metals. Our capacity: aluminium
bronze from 5 g to 2.5 kg and aluminium
alloys from 10 g to 6 kg.
