Name few alloys that contains non metal?

Answer 1

There are many:

• most iron alloys (e.g. cast iron, steels) contain carbon
• phosphor bronze contains phosphorus
• various hydride alloys contain hydrogen
• gallium arsenide (a binary semiconductor alloy) contains arsenic
• cadmium arsenide (a binary semiconductor alloy) contains arsenic
• some steel alloys contain silicon and/or phosphorus
• some alloys contain antimony
• etc.

Answer 2

Simple answer: Yes.

Many grades of steel contain trace amounts of Sulphur and Silicon to just name a couple. Other elements may also be introduced into alloys although their effect of the overall alloy is a different matter altogether. Typically however, non-metallic alloying elements tent to make up less than 1% of a ferrous alloy combined, put differently, non-metals tend to be present in steels but their proportion is virtually negligible (less the 0.05%)

In fact "mild steel" is an alloy of Iron - a metal - and Carbon - a non-metal. The proportion of carbon is very low but if correct will allow the steel to be hardened by heating and quenching.

Pure iron (no carbon) is quite soft and malleable so has little structural use - though in years past was "wrought iron" - but its behaviour in changing magnetic fields makes it eminently suitable for the cores of electrical inductance devices: motors, dynamos, Transformers etc.

Add too much carbon and the alloy is no longer steel but Cast Iron, in which the carbon exists as grains of graphite diffused through the metal. This makes it filthy to cut, though apart from a hard "skin" it is fairly soft; but cast-iron is an important material for machine components such as lathe beds, engine-blocks etc. It is easy to lubricate and tends to damp vibrations.
