|Had a person ask different type of balance wheel, was confuse with Glycuder wheel, it refer to material. Might help someone:D
Glucydur is a multi-metallic alloy, used in the watch industry for building different parts of the mechanism.
Glucydur is an alloy of beryllium, copper and iron. Due to such properties as hardness, resistance to deformation, damage or magnetic fields and its stability this alloy is perfect for making balance wheels for watches' mechanisms. Glucydur is also resistant to corrosion; it is rather inert chemically. Due to these qualities it is extensively used in producing antimagnetic watches.
Glucydur was developed about the same time with another non-magnetic material - Nivarox.

Nivarox (Nicht Variable Oxydfest - Not Variable Resistant to Oxidation) is a metallic alloy, which is used mainly in the watch industry. This alloy composed of iron, 40 % nickel, chromium, titanium and beryllium has properties, which are very useful in building the balances. The hairsprings made of this alloy will not wear out; they are almost non-magnetic, anti-rust and they have a very low coefficient of thermal expansion.
Nivarox stabilizes the movement of the watch and makes it more resistible to changing of the temperature. This alloy made obsolete the expensive and sophisticated compensation balance. Nivarox escape wheels are being used on different levels of production by most watchmakers worldwide.
Nivarox is produced exclusively by a single Swiss manufacturer - Nivarox-FAR.
